Abstract

V444 Cyg is a short-period (4 d) binary composed of two massive objects, a WN star and an O star. The winds of the two massive components collide, generating X-ray emission. A monitoring campaign in the high-energy domain was performed using Swift and XMM-Newton, with surprising results on the collision geometry (wide shock opening angle, clear Coriolis deflection). Polarimetric data further help to understand the system properties. This new information places strong constraints on the physical parameters of the two stars.
