Abstract
The results of analysis of new broad band U, J, K, photometric observations of WN5+06 binary V444 Cyg are presented. Comparison to the old optical data of Cherepashchuk et al. (1984) and IR data of Hartmann (1978) shows that the optical light curve is stable over more than 10 years, while the new infrared light curves are significantly different from the Hartmann’s ones. The difference between old and new infrared light curves poses a problem for clumpy structure of WR wind proposed by Cherepashchuk et al. as well as for standard smooth flow wind theory.
