Radial velocity of gamma Cas

Dear colleagues,

maybe the majority does have not much interest anymore, to observe Be stars.

But the radial velocity of the prototype of that star family, gamma Cas, finds today as in the past still a high interest in the professional community.

That’s why I continue to collect spectra of this star in order to support the professional research.

Enclosed you can see the RV monitoring of members of the ARAS group since September 2006 until now. Many thanks to all who contributed with their spectra.
