The Variability of Period of Beta Lyrae
Abstract
This paper contains a comprehensive list of 1216 primary and 812 secondary minima of the eclipsing variable Beta Lyrae. A mathematical representation of the O-C curve with second and third order term is given. The obtained elements: J.D. 240 8247.953(+/-11)+12.913800(+/-8)E+3.882(+-5)x10^-6E^-2 appear to be the most adequate for computation of ephemeris of primary minima.
