Title:Observational evidence for the interaction between the neutron star and the equatorial disk in BeX
Abstract:Be stars may have a lonely, boring and isolated life or a lively, exciting life if they are part of a binary system. In the latter case great fun happens when the companion is a neutron star. In principle, the physical properties of an isolated Be star are the same as that in a BeX. However, it is obvious that the presence of a second body (the neutron star) must have some effect on the observational properties of the system. As the equatorial disc is more exposed to the action of the neutron star, we would expect to see different properties in the discs of isolated Be compared to those of BeX. I will present the observational evidence that supports the existence of an interaction between the neutron star and the circumstellar disc, the most prominent consequence of this interaction being the truncation of the disc.
