Stars exploding as supernovae lose their mass to companion stars during their lives
Stars over eight times more massive than the sun end their lives in supernovae explosions. The composition of the star influences what happens during the explosion.

A new study published February 28 on arXiv.org suggests that a millisecond pulsar known as PSR J0740+6620 has a stellar companion. The research provides evidence indicating that this object is most likely accompanied by an ...
(Phys.org)—In 1604, a new star appeared in the night sky that was much brighter than Jupiter and dimmed over several weeks. This event was witnessed by sky watchers including the famous astronomer Johannes Kepler. Centuries ...
