Galactic Bulge Hypervelocity (HVS) RR Lyrae Variable Stars and One High Galactic Latitude HVS HB Star

Abstract

Six Galactic Bulge Hypervelocity (HVS) RR Lyrae stars and one high galactic latitude HVS Horizontal Branch (HB) star found from the ongoing search for HVS in the Gaia DR3 and SIMBAD data are presented. Some of these stars may be unbound and may be leaving the Galaxy. The source of the hyper velocities acquired by these stars may be the influence of the massive black hole at the center of our the Milky Way or other processes such as the dynamical interaction with other stars in the densely populated Galactic bulge.
