We generate constant rest-mass sequences of differentially rotating and uniformly rotating stars. The nucleonic matter relevant to the star interior is described within the framework of …
Web16 nov. 2024 · In 1988, J.G. Hills proposed a mechanism in which hyper-velocity stars (+1,000km/s) could obtain their massive speeds by being part of a binary system that interacts with a supermassive black hole. In this scenario, the energy of the binary pair is unleashed when one of the stars becomes bound to the supermassive black hole, … Web300 A.
