2151. Catalog of Earth-Like Exoplanet Survey Targets
ID:

Title:
Catalog of Earth-Like Exoplanet Survey Targets
Short Name:
J/AJ/151/59
Date:
21 Oct 2021
Publisher:
CDS
Description:
Locating planets in circumstellar habitable zones (HZs) is a priority for many exoplanet surveys. Space-based and ground-based surveys alike require robust toolsets to aid in target selection and mission planning. We present the Catalog of Earth-Like Exoplanet Survey Targets (CELESTA), a database of HZs around 37000 nearby stars. We calculated stellar parameters, including effective temperatures, masses, and radii, and we quantified the orbital distances and periods corresponding to the circumstellar HZs. We gauged the accuracy of our predictions by contrasting CELESTA's computed parameters to observational data. We ascertain a potential return on investment by computing the number of HZs probed for a given survey duration. A versatile framework for extending the functionality of CELESTA into the future enables ongoing comparisons to new observations, and recalculations when updates to HZ models, stellar temperatures, or parallax data become available. We expect to upgrade and expand CELESTA using data from the Gaia mission as the data become available.

Title:
Catalog of Eq.Widths of Interstellar 217nm Band
Short Name:
III/164
Date:

Publisher:
CDS
Description:
(from CDS Inf. Bull. 40, 31) The main task of the catalogue consists in a comprehensive collection of equivalent widths of the 217nm band derived from both spectrophotometric and filterphotometric measurements obtained with TD-1, OAO-2 and ANS satellites. These data concern reddened O, B stars with color excesses E(B-V) >= 0.02 mag. The extinction curve is approximated by the empirical formula introduced by Guertler et al. (1982AN....303..105G) e({lambda}) = A(i/{lambda} - 1/{lambda}o)^n^ + B + C {kappa}({lambda}) The relative errors amount to about {delta}A/A = +/- 0.10, {delta}B/B = +/- 0.02 and {delta}C/C = +/- 0.03.
2154. Catalog of extended extragalactic radio sources

Title:
Catalog of extended extragalactic radio sources
Short Name:
VIII/94
Date:

Publisher:
CDS
Description:
A catalog of extended extragalactic radio sources consisting of 10460 objects is compiled based on the list of radio sources of the FIRST survey. A total of 2339 objects are identified with galaxies and quasars of the SDSS survey and the Veron-Veron catalog. The distribution of position angles of the axes of radio sources from the catalog is determined, and the probability that this distribution is equiprobable is shown to be less than 10^-7^. This result implies that at Z equal to or smaller than 0.5, the spatial orientation of the axes of radio sources is anisotropic at a statistically significant level.
2155. Catalog of Extremely Red Objects

Publisher:
CDS
Description:
We use a serendipitously discovered overdensity of extremely red objects (EROs) to study the morphologies and cumulative surface number density of EROs in a dense environment. Our extremely deep imaging allows us to select very faint EROs, reaching K_S_=21, or ~2mag fainter than the L* of passively evolving ellipticals at z=1.5.
2156. Catalog of 3356 Faint Stars, 1950
ID:

Title:
Catalog of 3356 Faint Stars, 1950
Short Name:
I/16
Date:
21 Oct 2021
Publisher:
CDS
Description:
This catalog of 3356 faint stars was derived from meridian circle observations at the Bergedorf and Heidelberg Observatories. The positions are given for the equinox 1950 on the FK3 system. The stars are mainly between 8.0 and 10.0 visual magnitude. A few are brighter than 8.0 mag. The lower limit in brightness resulted from the visibility of the stars.
2157. Catalog of FHB stars aligned with HVCs
ID:

Title:
Catalog of FHB stars aligned with HVCs
Short Name:

Publisher:
CDS
Description:
We present a catalog of 430 field horizontal branch (FHB) stars, selected from the Hamburg/ESO Survey (HES), which fortuitously align with high column density neutral hydrogen (HI) high-velocity cloud (HVC) gas. These stars are ideal candidates for absorption-line studies of HVCs, attempts at which have been made for almost 40 years with little success. A parent sample of 8321 HES FHB stars (Christlieb et al., 2005, Cat. <J/A+A/431/143>) was used to extract HI spectra along each line of sight, using the HI Parkes All-Sky Survey (Putman et al., 2002, Cat. <J/AJ/123/873>). All lines of sight aligned with high-velocity HI emission with peak brightness temperatures greater than 120mK were examined. The HI spectra of these 430 probes were visually screened and cross-referenced with several HVC catalogs.
2158. Catalog of Galactic {beta} Cephei stars
ID:

Title:
Catalog of Galactic {beta} Cephei stars
Short Name:

Publisher:
CDS
Description:
We present an extensive and up-to-date catalog of Galactic {beta} Cephei stars. This catalog is intended to give a comprehensive overview of observational characteristics of all known {beta} Cephei stars, covering information until 2004 June. Ninety-three stars could be confirmed to be {beta} Cephei stars. We use data from more than 250 papers published over the last nearly 100 years, and we provide over 45 notes on individual stars. For some stars we reanalyzed published data or conducted our own analyses. Sixty-one stars were rejected from the final {beta} Cephei list, and 77 stars are suspected to be {beta} Cephei stars. A list of critically selected pulsation frequencies for confirmed {beta} Cephei stars is also presented.
2159. Catalog of Galactic OB Stars

Title:
Catalog of Galactic OB Stars
Short Name:
GALOBSTARS
Date:

Publisher:
NASA/GSFC HEASARC
Description:
An all-sky catalog of Galactic OB stars has been created by extending the Case-Hamburg Galactic Plane Luminous Stars surveys to include 5,500 additional objects drawn from the literature. This work brings the total number of known or reasonably suspected OB stars to over 16,000. This catalog contains UBV photometry and MK spectral type classifications for these objects as well as radial velocities. This project originated in the summer of 1991 when the author began compiling a cross-reference catalog and tabulation of published UBVbeta photometry for stars listed in Stephenson and Sanduleak&#39;s Luminous Stars (LS) in the Southern Milky Way Catalog (&lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/III/43"&gt;CDS Cat. III/43&lt;/a&gt;). This database was published in July 1993 (Reed 1993, ApJS, 87, 367) and was subsequently expanded to include compilations of published MK classifications (Reed &amp; Beatty 1995, ApJS, 97, 189), 4-color photometry (Read 1996, A&amp;AS, 117, 313), and radial velocities (Reed &amp; Kuhna 1997, AJ, 113, 823) for these objects. In mid-1997 the project was again expanded to include UBVbeta photometry for stars listed in the Northern-hemisphere volumes of the &quot;Case-Hamburg&quot; (&lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/III/76"&gt;CDS Cat. III/76&lt;/a&gt;) surveys (Reed 1998, ApJS, 115, 271); MK classifications for the Northern stars were similarly compiled and made electronically available to interested parties, though they were not formally published. Most of the LS objects are OB stars, but there are as well a number of A, F, and G supergiants and a few white dwarfs and Wolf Rayet stars. These surveys reached a limiting photographic magnitude of ~13.5, and were based on objective-prism surveys of dispersion 580 Angstrom/mm at H-gamma. OB stars is here taken to mean main-sequence stars down to temperature class B2 and more luminous ones down to temperature class B9. The original Case-Hamburg surveys (about 12,000 stars) also include some 2,000 evolved A-G stars, along with some white dwarfs, planetary nebulae, and Wolf-Rayet stars. It is worth noting that the definition of an OB star is not universal; for example, Vanbeveren et al. (1998, in &quot;The Brightest Stars&quot;) define them as O-B2 V-IV, O-B3 III, O-B4 II, and all OBA Ib, Iab, Ia, and IaO stars. This table was created by the HEASARC in September 2017 based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/V/125"&gt;CDS Catalog V/125&lt;/a&gt; files obcat.dat, obmk.dat, obubvbet.dat and radvel.dat.

2160. Catalog of galaxies around PKS 0405-123
ID:

Title:
Catalog of galaxies around PKS 0405-123
Short Name:
J/MNRAS/434/1765
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present new absorption-line analysis and new galaxy survey data obtained for the field around PKS 0405-123 at z_QSO_=0.57. Combining previously known OVI absorbers with new identifications in the higher S/N ultraviolet (UV) spectra obtained with the Cosmic Origins Spectrograph, we have established a sample of 7 OVI absorbers and 12 individual components at z=0.0918-0.495 along the sightline towards PKS 0405-123. We complement the available UV absorption spectra with galaxy survey data that reach 100 percent completeness at projected distances {rho}<200kpc of the quasar sightline for galaxies as faint as 0.1L* (0.2L*) out to redshifts of z~0.35 (z~0.5). The high level of completeness achieved at faint magnitudes by our survey reveals that OVI absorbers are closely associated with gas-rich environments containing at least one low-mass, emission-line galaxy. An intriguing exception is a strong OVI system at z~0.183 that does not have a galaxy found at {rho}<4Mpc, and our survey rules out the presence of any galaxies of L>0.04L* at {rho}<250kpc and any galaxies of L>0.3L* at {rho}<1Mpc. We further examine the galactic environments of OVI absorbers and those 'Ly{alpha}-only' absorbers with neutral hydrogen column density log N(HI)<13.6 and no detectable OVI absorption features. The Ly{alpha}-only absorbers serve as a control sample in seeking the discriminating galactic features that result in the observed Ovi absorbing gas at large galactic radii. We find a clear distinction in the radial profiles of mean galaxy surface brightness around different absorbers. Specifically, Ovi absorbers are found to reside in regions of higher mean surface brightness at {rho}<~500kpc ({Delta}{mu}_R_~+5magMpc^-2^ relative to the background at {rho}>500kpc), while only a mild increase in galaxy surface brightness is seen at small {rho} around Ly{alpha}-only absorbers ({Delta}{mu}_R_~+2magMpc^-2^). The additional insights gained from our deep galaxy survey demonstrate the need to probe the galaxy populations to low luminosities in order to better understand the nature of the absorbing systems.
