THE EVOLUTIONARY STATE OF THE MASSIVE INTERACTING BINARY BD+36°4063
We present a spectroscopic and photometric analysis of the remarkable massive binary system, BD+36°4063. We argue that the visible ON star is undergoing a rapid mass transfer episode that results in a thick and opaque disk that surrounds and renders invisible its massive companion. A comparison of the projected rotational …
