- Description:
- This table contains the 4th edition of the Catalog of High-Mass X-Ray Binaries (HMXBs) in the Galaxy. The catalog contains source name(s), coordinates, finding charts, X-ray luminosities, system parameters, and stellar parameters of the components and other characteristic properties for 114 HMXBs, together with a comprehensive selection of the relevant literature. The aim of this catalog is to provide some basic information on the X-ray sources and their counterparts in other wavelength ranges (gamma-rays, UV, optical, IR, radio). About 60% of the high-mass X-ray binary candidates are known or suspected Be/X-ray binaries, while 32% are supergiant/X-ray binaries. Some sources, however, are only tentatively identified as high-mass X-ray binaries on the basis of their X-ray properties similar to the known high-mass X-ray binaries. Further identification in other wavelength bands is needed to finally determine the nature of these sources. In cases where there is some doubt about the high-mass nature of the X-ray binary this is noted. Literature published before 1 October 2005 has, as far as possible, been taken into account.

- Catalog of high proper motion stars
- Short Name:
- IV/28A
- Date:
- 21 Oct 2021
- Publisher:
- CDS
- Description:
- The database of stars with high-proper motions (more than 0.04"/year) has been compiled using original definitions from catalogue FONAK1.0, the data of catalogues Hipparcos, Tycho-2, CMC (STAR 11), PPM, NPM1, NLTT,GCVS, Lowell Proper Motion, Bruce Proper Motion as well as the data of about 725 other published sources. The list consist of 251000 such stars with limiting magnitude 16 (companions for multiple systems up to 17) in a declination zone from -2 to +90 degrees. Besides astrometric parameters (equatorial coordinates, proper motions, estimations of stars magnitudes) the database includes some astrophysical characteristics (magnitudes in UBVRI system, radial velocities, spectra, luminosity class, metallicity; flags of multiple system, of variable star and other). For convenience of usage original numbers of stars from different catalogues the author's lists of stars and basic sources are given too. At present the database includes codes of 56 catalogues and author's lists of stars. The cross index list is given by a file of 228397 stars arranged by right ascension. Star information is recorded in a digital integer form with one line. Thus maximum amount of star numbers from catalogues and author's lists does not exceed 10 (if more, the number of lines for star is increased by unit).

- Description:
- In preparation for the upcoming all-sky data releases of the Gaia mission we compiled a catalog of known hot subdwarf stars and candidates drawn from the literature and yet unpublished databases. By matching this catalog with astrometric and photometric data from the Gaia mission, we will develop selection criteria to construct a homogeneous, magnitude-limited all-sky catalog of hot subdwarf stars based on Gaia data.

- Description:
- In this paper we analyze a sample of metal-rich (>-0.8dex) main sequence stars in the extended solar neighborhood, investigating kinematic outliers from the background population. The data, which are taken from the Sloan Digital Sky Survey, are kinematically profiled as a function of distance from the Galactic plane using full six-dimensional phase space information. Each star is examined in the context of these kinematic profiles and likelihoods are assigned to quantify whether a star matches the underlying profile. Since some of these stars are likely to have been ejected from the disk, we trace back their orbits in order to determine potential ejection radii. We find that objects with low probability (i.e., "outliers") are typically more metal-poor, faster and, most importantly, have a tendency to originate from the inner Galaxy compared to the underlying population. We also compose a sample of stars with velocities exceeding the local escape velocity. Although we do not discount that our sample could be contaminated by objects with spurious proper motions, a number of stars appear to have been ejected from the disk with exceptionally high velocities. Some of these are consistent with being ejected from the spiral arms and hence are a rich resource for further study. Finally we look at objects whose orbits are consistent with them being ejected at high speeds from the Galactic center. Of these objects we find that one, J135855.65+552538.19, is inconsistent with halo, bulge and disk kinematics and could plausibly have been ejected from the Galactic nucleus via a Hills mechanism.

- Description:
- The field of computer vision has greatly matured in the past decade, and many of the methods and techniques can be useful for astronomical applications. One example is in searching large imaging surveys for objects of interest, especially when it is difficult to specify the characteristics of the objects being searched for. We have developed a method using contour finding and convolution neural networks (CNNs) to search for Infrared Dark Clouds (IRDCs) in the Spitzer Galactic plane survey data. IRDCs can vary in size, shape, orientation, and optical depth, and are often located near regions with complex emission from molecular clouds and star formation, which can make the IRDCs difficult to reliably identify. False positives can occur in regions where emission is absent, rather than from a foreground IRDC. The contour finding algorithm we implemented found most closed figures in the mosaic and we developed rules to filter out some of the false positive before allowing the CNNs to analyze them. The method was applied to the Spitzer data in the Galactic plane surveys, and we have constructed a catalog of IRDCs which includes additional parts of the Galactic plane that were not included in earlier surveys.

- Catalog of Infrared Observations (CIO), Edition 5
- Short Name:
- CIO
- Date:
- 25 Apr 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Fifth Edition of the Catalog of Infrared Observations (CIO) comprises a summary of infrared astronomical observations published in the scientific literature from 1965 through 1997 in the wavelength range 1 micrometer (= 1 micron = 1 um) to 1 millimeter (= 1 mm). This catalog contains infrared observational data for sources outside the Solar System, constructed through a search of the most active scientific journals, IR surveys and catalogs. To date, about 6200 journal articles and 10 major survey catalogs have been included in the database from which this catalog was constructed. The catalog in its original form contains 374,653 individual observations of about 62,000 different infrared sources. More than 8000 of these sources are identifiable with visible objects. For sources with no published IR source position, a nominal position may have been given based on other sources. Nominal positions are usually the best available, but not necessarily the true IR positions. The HEASARC has removed 1136 of the 374,653 entries in the catalog in its original form for which there was no positional information, leaving 373,517 remaining entries in this HEASARC-realized version. The 1136 entries that were removed are listed in the file: <a href="https://heasarc.gsfc.nasa.gov/FTP/heasarc/dbase/misc_files/infrared/deleted_entries.txt">https://heasarc.gsfc.nasa.gov/FTP/heasarc/dbase/misc_files/infrared/deleted_entries.txt</a> In addition to the main catalog, the creators of CIO also generated other files, e.g., bibliographical files, an index file, etc., which are available via the web (in the form of gzipped ASCII files) in the directory: <a href="https://heasarc.gsfc.nasa.gov/FTP/heasarc/dbase/misc_files/infrared/">https://heasarc.gsfc.nasa.gov/FTP/heasarc/dbase/misc_files/infrared/</a>. The bibliographical files (refauth.data.gz refchron.dat.gz, and refs.dat.gz) link observations in the catalog with references to the original articles published in the literature (these references give the standard information plus the full titles). The Index of Infrared Source Positions is contained in the file names.dat.gz and is ordered alphabetically by source name: for sources with no published IR source position, a nominal position (usually the best available, but not necessarily the true IR position) may have been given based on other sources. Nominal position references are indicated in the index. This version of the 5th Edition of the Catalog of Infrared Observations was created by the HEASARC in April 2001 based on ADC/<a href="https://cdsarc.cds.unistra.fr/ftp/cats/II/225">CDS catalog <II/225></a>. Duplicate entries were removed in June 2019. This is a service provided by NASA HEASARC .

- Catalog of Kepler flare stars
- Short Name:
- J/ApJS/232/26
- Date:

- Publisher:
- CDS
- Description:
- We aim to perform a statistical study of stellar flares observed by Kepler. We want to study the flare amplitude, duration, energy, and occurrence rates, and how they are related to the spectral type and rotation period. To that end, we have developed an automated flare detection and characterization algorithm. We have harvested the stellar parameters from the Kepler input catalog and the rotation periods from McQuillan et al. (2014, Cat. J/ApJS/211/24). We find several new candidate A stars showing flaring activity. Moreover, we find 653 giants with flares. From the statistical distribution of flare properties, we find that the flare amplitude distribution has a similar behavior between F+G types and K+M types. The flare duration and flare energy seem to be grouped between G+K+M types versus F types and giants. We also detect a tail of stars with high flare occurrence rates across all spectral types (but most prominent in the late spectral types), and this is compatible with the existence of "flare stars." Finally, we have found a strong correlation of the flare occurrence rate and the flare amplitude with the stellar rotation period: a quickly rotating star is more likely to flare often and has a higher chance of generating large flares.

- Description:
- Infrared (IR) excesses around K-type red giants (RGs) have previously been discovered using Infrared Astronomy Satellite (IRAS) data, and past studies have suggested a link between RGs with overabundant Li and IR excesses, implying the ejection of circumstellar shells or disks. We revisit the question of IR excesses around RGs using higher spatial resolution IR data, primarily from the Wide-field Infrared Survey Explorer. Our goal was to elucidate the link between three unusual RG properties: fast rotation, enriched Li, and IR excess. Our sample of RGs includes those with previous IR detections, a sample with well-defined rotation and Li abundance measurements with no previous IR measurements, and a large sample of RGs asserted to be Li-rich in the literature; we have 316 targets thought to be K giants, about 40% of which we take to be Li-rich. In 24 cases with previous detections of IR excess at low spatial resolution, we believe that source confusion is playing a role, in that either (a) the source that is bright in the optical is not responsible for the IR flux, or (b) there is more than one source responsible for the IR flux as measured in IRAS. We looked for IR excesses in the remaining sources, identifying 28 that have significant IR excesses by ~20{mu}m (with possible excesses for 2 additional sources). There appears to be an intriguing correlation in that the largest IR excesses are all in Li-rich K giants, though very few Li-rich K giants have IR excesses (large or small). These largest IR excesses also tend to be found in the fastest rotators. There is no correlation of IR excess with the carbon isotopic ratio, ^12^C/^13^C. IR excesses by 20{mu}m, though relatively rare, are at least twice as common among our sample of Li-rich K giants. If dust shell production is a common by-product of Li enrichment mechanisms, these observations suggest that the IR excess stage is very short-lived, which is supported by theoretical calculations. Conversely, the Li-enrichment mechanism may only occasionally produce dust, and an additional parameter (e.g., rotation) may control whether or not a shell is ejected.
