Eclipses in V444 Cygni: analysis of the continuum λ 4244 Å light-curve on a class of non-negative monotonically decreasing concaved/convex functions

  • Igor I. Antokhin (a1) and Anatol M. Cherepashchuk (a1)

Abstract

A continuum λ 4244 Å light-curve of the eclipsing binary V444 Cyg (WN5+O6) is solved. The results generally agree with the previous ones obtained by Antokhin et al. (1997), with the exception that the conclusion on the slowness of the acceleration in the extended atmosphere of the WR component must be ‘softened’.
