Publications of the Astronomical Society of the Pacific Vol. 131, No. 995, 2019 January Angular Momentum of Stars and their Plan... To understand the distribution of angular momenta between host stars ...

When they are formed, neutron stars rotate in space. As they compress and shrink, this spinning speeds up because of the conservation of angular momentum—the same principle that causes a ...

The fastest-spinning white dwarf ever discovered is a shrinking cosmic vampire feasting on a stellar companion. A feeding process is pushing the dead star toward an imminent supernova explosion.

surrounded by a ring of hot matter in fast rotation that contains a small fraction of the mass but a large fraction of the angular momentum. Unlike most stars, the inner remnant has a higher ...

At first the circumstellar disk is in a phase called an accretion disk, where mass is transported inward toward the star and angular momentum is transported outward. Planet formation likely occurs ...

The white dwarf, or dead star, in question is the compact companion ... This is difficult to explain, given the low rate of accreted mass and angular momentum," Mereghetti told Space.com.
