Abstract
Oe stars are thought to represent an extension of the Be phenomenon to higher temperatures. Dedicated XMM observations of HD155806 revealed a surprising X-ray spectrum: soft character, absence of overluminosity, broad X-ray lines. These properties are fully compatible with the wind-shock model, which usually explains the X-rays from “normal”, single O-type stars. In contrast, some other Oe/Be stars display a completely different behaviour at high energies.
