Three-dimensional distribution of high-velocity stars

Numerical calculations support the conjecture that high velocity stars born in or near the rotating disk are not distributed spherically throughout the galaxy. Instead an empty funnel region forms around the rotation axis of the galaxy, where no stars reside. The funnel appears only for high velocity stars, such as old pulsars. Within about 50 kpc distance from the galactic center the funnel shape is almost not dependent on the existence of a massive corona.     

Absolute proper motions of blue objects in the vicinity of M33

36 objects with mainly negative (U—B) indices were investigated for variability and proper motions. 10 objects with significant or suspected proper motions and 8 variable objects were detected. Using these criteria, it was possible to separate white dwarfs from quasi-stellar objects to some extent.
