Here is a state-of-the-art review of our current knowledge of brown dwarfs and very low-mass stars. The hunt for, and study of, these elusive objects is currently one of the most dynamic areas of ...

This rare stellar speedster is the first "hypervelocity" very low mass star found ... low-mass companion of a white dwarf.

Radio pulsars —rapidly spinning neutron stars —are well-studied objects. They typically spin many times a second to a few ...

The Hubble Space Telescope has been used to determine the mass of white dwarf star LAWD 37. It is "56 percent the mass of our Sun," according to NASA/ESA. Credit: NASA, ESA, P. McGill (Univ.

White dwarfs typically have a radius just .01 times that of our own sun, but their mass is about the same. Stars like our sun fuse hydrogen in their cores into helium. White dwarfs are stars that ...

Astronomers have tracked a mysterious, record-breaking blast of energy to a binary star system containing a red dwarf star ...

Astronomers have discovered the first pairs of white dwarf ... massive stars tend to live shorter lives and go through the stages of stellar evolution much faster than their lower mass companions.

It is the result of a pair of stars sharing a common outer layer during their last moments. Astronomers at the University of Toronto (U of T) have discovered the first pairs of white dwarf and ...
