J/BaltA/5/1   Classification of Population II stars  (Bartkevicius+, 1996)

Classification of population II stars in the Vilnius photometric system. I. Methods Bartkevicius A., Lazauskaite R. <Baltic Astronomy, 5, 1 (1996)> =1996BaltA...5....1B
ADC_Keywords: Stars, population II ; Photometry, Vilnius ; Abundances, [Fe/H] Keywords: photometry - stars: fundamental parameters - stars: population II Description: The astrophysical parameters compiled from literature for 809 stars of different types, mainly Population II stars, are presented. The results of classification in the Vilnius photometric system for the same stars are given. For a description of the Vilnius photometric system, see e.g. GCPD/21 File Summary:

Note (1): Identification number is on code described by Mermilliod (1978BICDS..14...32M). Coding of identification numbers is explained in General Photometric Catalogue of Stars Observed in the Vilnius System (Straizys & Kazlauskas, 1993BaltA...2....1S). Note (2): In the case of [Fe/H] derived from high-resolution spectra, the values are given to two decimal places. Note (3): In the case of MV calculated from trigonometric parallaxes, the values are given to two decimal places. Note (4): Results of classification in the Vilnius system Note (5): Brackets indicate uncertain spectral type Note (6): ":" - uncertain, "::"- very uncertain

Note (1): Abbreviations used: KAPT: Kapteyn star group (Members of moving groups of stars) GR1830: Gr 1830 star group (Members of moving groups of stars) ARCT: Arcturus star group (Members of moving groups of stars) PUP: sigma Puppis star group (Members of moving groups of stars) VB: Visual binary VB?: Suspected visual binary VB-MD: Population II visual binary, observed separate components VBP-MD: Population II visual binary with d<10-15arcsec and {DELTA}m>4mag, both components observed together VBP: Population I visual binary with d<10-15arcsec and {DELTA}m>4mag, both components observed together IDS: Number from Worley C., Douglass G. 1984, The Washington Visual Double Star Catalogue, 1984.0, See Cat. I/237. First numeral is the distance between components in arcsec, second numeral is the difference of magnitudes. When the orbit is given, the next numeral means the semi-major axis of the VB orbit in arcsec, number after P is the period in years. (Visual binaries) SB: Spectroscopic binary SB?: Suspected SB, P is the period in days, K is the semiamplitude of the radial velocity curve in km/s. CPM: Comon proper motion Var RV: Variable radial velocity Var RV?: Suspected variable radial velocity VAR: Variable star, P is the period in days, V, PG and B are the corresponding magnitudes in maximum and minimum. Data are from P. N. Kholopov (Ed.), General Catalogue of Variable Stars, 4-th ed. Cat. II/139
