V/101               Nearest stars until 10pc     (Zakhozhaj, 1979-1996)

Catalogue of nearest stars until 10pc Zakhozhaj V.A. <Vestnik Khar'kovskogo Universiteta 190, 52 (1979)> =1979VKha..190...52Z
ADC_Keywords: Stars, nearby ; Stars, masses ; Stars, diameters ; Proper motions ; Parallaxes, spectroscopic ; Parallaxes, trigonometric Keywords: Stars, nearby, masses, radii - Astrometric data - Spectral types - Magnitudes, absolute Description: The given catalogue is a revised version of the catalogue (Zakhozhaj, 1987). The previous numeration is preserved, and the stars, with trigonometric, photometric and spectral parallaxes >0.100" are presented. The catalogue contains data on new components of multiple visual systems, on the components of spectral-binary systems, on invisible components with masses >0.08 solar mass. New data are obtained in 90s and contained in the articles [2-6]. The catalogue contains the main characteristics of stars such as the positions, proper motions, radial velocities, parallaxes, photometrical data and also new data of masses and radii of stars. The completeness of the catalogue is about 70%. File Summary:

Note (1): Coordinates of multiple system components are calculated on the basis of the angular separation and position of observation epoch. Note (2): *: pmRA and pmDE for multiple system components are calculated by the common proper motion and the position angle. Note (3): t: trigonometric parallax p: photometric parallax s: spectral parallax r: average value of t, p and s parallaxes a: average value of p and s parallaxes o: photometric or spectral parallax Note (4): *: The values of parallaxes with error of 10% and more. Note (5): v: variable star S: summarized magnitude of components, n: author' estimation of Vmag and Mv are made for visible component or for component for which it is possible to estimate component spectrum. Note (6): e: emission lines p: peculiar spectra w: weak spectra lines c: evaluation of spectral class on the basis of known index of colour m: spectra of multiple system component l: luminosity class is estimated by the diagram "colour-luminosity"Note (7): t: estimated by the relation of 'mass-effective temperature' Note (7): t: estimated by the relation of 'mass-effective temperature' c: calculated by the analysis of the line-of-sight curve of spectral binary stars S: summarized mass of seen and unseen components d: calculated by direct methods of mass measurement. w: calculated for white dwarfs by mass-radii relation Note (8): t: estimated by the radii-effective temperature relation w: calculated for white dwarfs by mass-radii relation r: calculated by (V-R)-radii relation d: calculated by direct methods of radii measurement
