This illustration depicts a binary star system consisting of a dense neutron ... the neutron star is dormant—it is not actively stealing mass from its companion and is thus very faint.

It was discovered that V2787 Ori is a shallow-contact, total-eclipsing binary with a factor of f = 0.181(±0.077) and an extremely low mass ratio of q = 0.120(±0.002). The primary contributes about 95% ...

The binary star system discovered in the new study is the heaviest of its kind that's ever been confirmed, with a combined mass that's 1.56 times that of the sun. At this magnitude, the two stars ...
