Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a peculiar cataclysmic variable star. The newly found system, designated SDSS J134441.83+204408.3 (or J1344 for short) is a highly asynchronous, ...
Using the Southern African Large Telescope (SALT), an international team of astronomers has discovered eight new very hot white dwarf and pre-white dwarf stars with effective temperatures over 100,000 K. The finding is reported ...
A Dartmouth professor's images of the explosive aftermath from the collision of two dying stars could help scientists better understand this rare type of astronomical event—and may finally confirm the identity of a brilliant ...
