We present the catalogue of averaged quadratic effective magnetic fields <B_e_> for 596 main sequence and giant stars. The catalogue is derived from measurements of the stellar effective magnetic field strengths B_e_, which were compiled from the existing literature.
2322. Catalogue of Stellar Spectral Classifications
ID:
ivo://CDS.VizieR/B/mk
Title:
Catalogue of Stellar Spectral Classifications
Short Name:
B/mk
Date:
21 Oct 2021
Publisher:
CDS
Description:
This file contains spectral classifications for stars collected from the literature, serving as a continuation of the compilations produced by the Jascheks, by Kennedy, and by Buscombe. The source of each spectral type is indicated by a standard 19-digit bibcode citation. These papers of course should be cited in publication, not this compilation. The stars are identified either by the name used in each publication or by a valid SIMBAD identifier. Some effort has been made to determine accurate (~1" or better) coordinates for equinox J2000 (and epoch 2000 if possible), and these serve as a secondary identifier. To the extent possible with current astrometric sources, the components of double stars and stars with composite spectra are shown as separate entries. Magnitudes are provided as an indication of brightness, but these data are not necessarily accurate, as they often derive from photographic photometry or rough estimates. The file includes only spectral types determined from spectra (viz. line and band strengths or ratios), omitting those determined from photometry (e.g. DDO, Vilnius) or inferred from broadband colors or spectral energy distributions. The classifications include MK types as well as types not strictly on the MK system (white dwarfs, Wolf-Rayet, etc), and in addition simple HD-style temperature types. Luminosity classes in the early Mount Wilson style (e.g. 'd' for dwarf, 'g' for giant) and other similar schemes have been converted to modern notation. Since a citation is provided for each entry, the source paper should be consulted for details about classification schemes, spectral dispersion, and instrumentation used. System-defining primary MK standard stars are included from the last lists by Morgan and Keenan, and are flagged by a + sign in column 83. The early-type standards comprise the 1973 "dagger standards" (1973ARA&A..11...29M) and stars from the Morgan, Abt, and Tapscott atlas (1978rmsa.book.....M). Standards from Table I of the Morgan & Abt 'MKA' paper (1972AJ.....77...35M) not appearing in the two later lists are added. Keenan made continual adjustments to the standards lists up to the time of his death. Thus the late-type standards comprise those marked as high-weight standards in the 1989 Perkins catalogue (1989ApJS...71..245K = III/150); the revised S-type standards in collaboration with Boeshaar (1980ApJS...43..379K); plus the carbon standards and class IIIb 'clump giants' in collaboration with Barnbaum (1996ApJS..105..419B and 1999ApJ...518..859K). In addition, I have made use of the final types by Keenan up to January 2000 shown at the Ohio State Web site (http://www.astronomy.ohio-state.edu/MKCool), accessed in autumn 2003. Though the present file contains all the stars in these lists, only those marked as standards are flagged as such. Garrison's list of MK 'anchor points' might also be consulted in this regard (1994mpyp.conf....3G, and http://www.astro.utoronto.ca/~garrison/mkstds.html). The catalogue includes for the first time results from many large-scale objective-prism spectral surveys done at Case, Stockholm, Crimea, Abastumani, and elsewhere. The stars in these surveys were usually identified only on charts or by other indirect means, and have been overlooked heretofore because of the difficulty in recovering the stars. More complete results from these separate publications, including notes and identifications, have been made available to the CDS, and are kept at the Lowell Observatory ftp area (ftp://ftp.lowell.edu/pub/bas/starcats). Not all of these stars are present in SIMBAD. As a 'living catalogue', an attempt will be made to keep up with current literature, and to extend the indexing of citations back in time.

ivo://CDS.VizieR/V/53A
Title:
Catalogue of the Brightest Stars
Short Name:
V/53A
Date:
21 Oct 2021
Publisher:
CDS
Description:
This catalogue provides data on the 1628 stars brighter than magnitude 5.01 contained in the "catalogue des etoiles les plus brillantes" by Ochsenbein et al. (1984), compiled from the fourth edition of The Bright Star Catalogue (Hoffleit 1982). It differs from the original printed version by the following points: - the star designations in Hipparcos catalogue were added, as well as the positions expressed in the International Celestial Reference System (ICRS) (A) - the parallax and proper motion data were replaced by the Hipparcos values for almost all the bright stars (A) - the distances (expressed in light-years) were computed (A) - ecliptic coordinates were added to astrometric data - UBVRI photometry was taken from Lanz (1986); for that reason, three stars (HR 3229, HR 4392 and HR 6161) are fainter than 5 mag. Moreover, the blanks due to unknown indices were filled with the value 99.99 (or 99.999 for the uvbyHbeta photometry). - the greek letter "delta" that appears in some spectral types is now written in latin letters instead of the code "<04>". - the luminosity classes are coded as integer numbers in an additional column. - the number of components of visual double stars is given. (A) indicates data added for version 'A'
2326. Catalogue of UVBGRI measurements

Title:
Catalogue of UVBGRI measurements
Short Name:
II/8
Date:

Publisher:
CDS
Description:
This compilation contains the published results and the weighted means of the observations in the photoelectric photometric system described by Stebbins and Withford (1943). The six filters were selected to give nearly the same response in each of the six spectral regions for a solar-type star. The mean wavelengths or the filters are: ---------------------------------------------------- Filter U B V G R I Wavelength (nm) 353 422 488 570 719 1030 ---------------------------------------------------- The reduction of this system is made in order that (B+G+R) = 0.

2328. Catalogue of white dwarfs in Gaia EDR3
ID:

Title:
Catalogue of white dwarfs in Gaia EDR3
Short Name:
J/MNRAS/508/3877
Date:
06 Dec 2021 19:56:36
Publisher:
CDS
Description:
We present a catalogue of white dwarf candidates selected from Gaia Early Data Release 3 (EDR3). We applied several selection criteria in absolute magnitude, colour, and Gaia quality flags to remove objects with unreliable measurements while preserving most stars compatible with the white dwarf locus in the Hertzsprung-Russell diagram. We then used a sample of over 30000 spectroscopically confirmed white dwarfs and contaminants from the Sloan Digital Sky Survey (SDSS) to map the distribution of these objects in the Gaia absolute magnitude-colour space. Finally, we adopt the same method presented in our previous work on Gaia Data Release 2 (DR2) to calculate a probability of being a white dwarf (P_WD_) for ~=1.3 million sources that passed our quality selection. The P_WD_ values can be used to select a sample of \simeq 359000 high-confidence white dwarf candidates. We calculated stellar parameters (effective temperature, surface gravity, and mass) for all these stars by fitting Gaia astrometry and photometry with synthetic pure-H, pure-He, and mixed H-He atmospheric models. We estimate an upper limit of 93 per cent for the overall completeness of our catalogue for white dwarfs with G>=20mag and effective temperature (T_eff_)>7000K, at high Galactic latitudes (|b|>20{deg}). Alongside the main catalogue we include a reduced proper motion extension containing ~=10200 white dwarf candidates with unreliable parallax measurements that could, however, be identified on the basis of their proper motion. We also performed a cross-match of our catalogues with SDSS Data Release 16 (DR16) spectroscopy and provide spectral classification based on visual inspection for all resulting matches.
2329. Catalogue of X-ray binaries
ID:
ivo://CDS.VizieR/V/106
Title:
Catalogue of X-ray binaries
Short Name:
V/106
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a catalogue of high-mass X-ray binaries. The catalogue is an updated version of the catalogue of van Paradijs (1995, Cat. <V/90>). The new high-mass catalogue contains 130 sources, 61 new high-mass X-ray binaries in addition to the 69 sources listed in van Paradijs' catalogue. Most of the new sources are identified to be Be/X-ray binaries. Some sources, however, are only tentatively identified as high-mass X-ray binaries on the basis of a transient character and/or a hard X-ray spectrum. Further identification in other wavelength bands is needed to finally determine the features of these sources. The new low-mass catalogue contains 150 sources, 31 new low-mass X-ray binaries in addition to the 119 sources listed in van Paradijs' catalogue. The aim of this catalogue is to provide the reader with some basic information on the X-ray sources and their counterparts in other wavelength ranges (UV, optical, IR, radio). In cases where there is some doubt about the high or low-mass nature of the X-ray binary this is mentioned. Some doubtful cases have not been included in the catalogue although they had been suggested by some authors to be high-mass X-ray binaries, for example GRS 1915+105 and 1WGA J1958.2+3232.
2330. Catalogue of X-Ray Binaries
ID:
ivo://CDS.VizieR/V/90
Title:
Catalogue of X-Ray Binaries
Short Name:
V/90
Date:
21 Oct 2021
Publisher:
CDS
Description:
The objects described in this catalog are X-Ray binaries, i.e., semi-detached binary stars in which matter is transferred from a usually more or less normal star to a neutron star or black hole. Thus, cataclysmic variables are not included. The tables provide basic information of the systems as well as selected references. The tables contain 124 low-mass and 69 high mass X-ray binaries.
