Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new massive brown dwarf. The newfound object is nearly 80 times more massive than Jupiter and orbits an M-dwarf star known as TOI-5375. ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new, warm Jupiter-sized exoplanet orbiting a dwarf star. The newfound alien world, designated TOI-4127 b, is more ...
A white dwarf star can explode as a supernova when its mass exceeds the limit of about 1.4 solar masses. A team led by the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching and involving the University of ...
