A model for the enhanced production rate of early-type hypervelocity stars in the Galactic halo

Kavli Affiliate: Fukun Liu| Summary: About twenty late B-type hypervelocity stars (HVSs) traveling faster than the Galactic escape velocity have been discovered in the Galactic halo, many of which were ejected from the Galactic center (GC). Recently, we have advocated that these HVSs most likely formed in the nuclear star cluster (NSC) $150$–$500, rmMyr$ ago […]
