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

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 WR+O binary – Fredholm’s equations of the first kind. The unknown functions are the brightness and opacity distributions across the disc of the WR comp...
