Astronomers have strengthened long-standing predictions that massive runaway stars could have originated in binary pairs, and were dramatically ejected into space when their companion stars underwent supernova explosions. ...
Researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), in collaboration with the Institute of Astrophysics of the Canary Islands (IAC), ...
