III/273 Radial velocities of 107 B8-A0 stars (Albitzky, 1947) ================================================================================ Radial velocities of 107 B8-A0 stars. Albitzky V.A. =1947IzKry...1...23A =2014yCat.3273....0A ================================================================================ ADC_Keywords: Radial velocities ; Stars, high-velocity Keywords: velocities: stars: optical Abstract: The observations of radial velocities of B8-A0 stars were produced in 1932-1937 with one-prism spectrograph and short camera giving a dispersion of 75{AA}/mm at H{gamma}. When reducing the observations the systematic error as described in our previous paper (I) has been taken into account. From the comparison of the radial velocities of 7 stars in common with two catalogues the systematic correction to our radial velocities was deduced, viz.+0.44+/-1.51km/s in the sense Moore-Simeis. In table XII there are given the final radial velocities for 91 stars with mean value of p.e. equal to +/-3.57km/s. In table XII are given observed velocities for 16 stars with variable radial velocities. Very large velocity of the star HD 161817 leads to the conclusion that this star belongs to the class of high-velocity stars. Description: In Table XII are given the final values of the observed radial velocities for 107 stars. For 16 of these stars the radial velocities have been admitted to be variable which makes 14% of the total number of the stars observed. This percentage is smaller than that usually accepted, viz. about 25-30%; but with so small dispersion as ours one must be more careful in announcing the variability of a radial velocity. The data of the Table XII are self-explanatory; the magnitudes are visual and the spectral types are those of H.D. in the column 8 are given the numbers of spectrograms measured. In the remarks betGC signifies Burnham's General catalogue of Double Stars, etc.; Moore - J.H. Moore, General Catalogue of the Radial Velocities of Star, etc.; D.D.O. - Publications of the David Dunlap Observatory, University of Toronto, Vol. I, Nr. 3. (2). For 91 stars with adopted constant velocities the mean value of p.e's is +/-3.57km/s and the number of spectrograms per star is 5.3. For the catalogue D.D.O. corresponding data are +/-2.85km/s and 5.8 (for stars B8-A0). The lower precision of the present catalogue may be explained by the small dispersion of our spectrograph: 75{AA}/mm instead of 33-66{AA}/mm for D.D.O.
