Há 5 dias · After astronomers pinpoint a rapidly brightening point of light in a distant galaxy — a new supernova! — they hunt through archival data to learn more about the star that exploded. Using this method, researchers have tracked down dozens of supernova progenitor stars and have learned that core-collapse supernovae usually arise from red supergiant stars with masses in the range of 8 to 18 ...
Há 2 dias · Many of the thousands of neutron stars known in the Milky Way are alone. But in a new analysis of data from the European Space Agency’s Gaia mission, Kareem El-Badry (Caltech) and colleagues have found 21 survivors: “dark” neutron stars in mutual orbit with Sun-like stars. The results are published in the Open Journal of Astrophysics.
