Tsih (Gamma Cassiopeiae)

Tsih is the Chinese name of the middle star in the big W of Cassiopeia. Oddly it doesn't have a western name.

It is a triple system, whereas the B star could be a white dwarf or even a neutron star. This would explain the strong X-radiation coming from Tsih.
The blue A, an emission star, is rotating extremely fast and therefore stripping ist hull out into space.
