WR22 = HD 92740 is a bright (V = 6.4 $mag$), intrinsically luminous, double-line WN7h + O9III-V binary exhibiting one sharp 8\% deep eclipse near periastron in its elliptical (e = 0.6) 80-day orbit, when the WR-star passes in front of the O star, wit

We report the discovery of a relatively bright eclipsing binary system, which consists of a white dwarf and a main sequence K7 star with clear signs of chromospheric and spot activity. The light curve of this system shows $\sim0.2$mag ellipsoidal var

Single-wall carbon carcass nanoparticles (nanohorns) (CNHs) are synthesized by two methods: electric arc and electron evaporation of graphite in the inert atmosphere. Distinctions in the structures of obtained materials are revealed using electron mi

Synthesis methods for light and radial velocity curves allow one to find the physical parameters of the components of binary systems of different types. We describe the basics of a new light curve synthesis algorithm for binaries that contain stars w

Solving light curves of WR+O binaries by Tikhonov’s regularization method

Autor: Igor I. Antokhin

Publikováno v: Monthly Notices of the Royal Astronomical Society. 420:495-504

Eclipsing Wolf–Rayet (WR)+O binaries are natural laboratories allowing one to study WR winds by analysing their light curves. We present a method of analysis based on solving the most general form of integral equations describing a light curve of a
