J/PAZh/24/443       Cepheid radii                            (Sachkov+, 1998)

The radii of 62 classical Cepheids. Sachkov M.E., Rastorguev A.S., Samus N.N., Gorynya N.A. <Pis'ma Astron. Zh. 24, 443 (1998)> =1998PAZh...24..443S =1998AstL...24..377S
ADC_Keywords: Stars, variable; Stars, diameters Abstract: Based on dense series of photoelectric observations and on our radial-velocity measurements, the radii of 62 northern Cepheids are calculated by Balona's method. For each star there are five radius calculations. Two color indices, (B-V) and (V-R), were used as the effective temperature indicators. All light curves in V, B-V and V-R magnitudes together with the descending part light curves were used to exclude shock-wave influence. For calculations of radii of spectroscopic binaries (=sb) were used pulsational radial velocity curves. File Summary:
