Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected a new low-mass, pre-main-sequence binary system. The newfound binary, designated 2M1222−57, contains two stars the size of the sun but ...
A team of researchers from Friedrich-Schiller-Universität Jena, Università di Torino and INFN sezione di Torino, has found evidence that the black hole collision that led to an odd gravitational wave detection in 2019 was ...
Researchers led by Ph.D. candidate Guo Yanjun from Yunnan Observatories of the Chinese Academy of Sciences (CAS) have explored the dependency of the intrinsic binary fraction on derived stellar effective temperature, metallicity ...

Indian astronomers have employed NASA's NuSTAR spacecraft to inspect an X-ray pulsar known as 1E 1145.1-6141. Results of the observations deliver important insights into the properties and nature of this pulsar. The study ...
Astronomers have observed directly for the first time how intense light from stars can 'push' matter. Researchers from the universities of Cambridge and Sydney made the observation when tracking a giant plume of dust generated ...
