How to calculate a phase shift in the process of deriving Baade-Wesselinke distance?
The above is the equation used in the Baade-Wesselink method to independently get distances to Cepheid variables (in the process of deriving Period-Luminosity relation).
According to the paper New ...

Are black holes solely responsible for hyper velocity stars?
I read that the stars orbiting around Sagittarius A* (a.k.a the supermassive black hole located at the heart of the Milky Way) move very fast (many times faster than our Sun moves across the galaxy), ...
