Scientists have proposed a new class of star, one with an exotic stellar engine that would emit mostly hard-to-detect neutrinos instead of photons of light like regular stars. These objects, dubbed ...

When small stars die, they collapse to form neutron stars in which the Pauli exclusion principle prevents further collapse. Anything more massive eventually becomes a black hole (with the cut off at ...

Physicists propose there may be a new stage for some dying stars. Dubbed electroweak stars, they are fueled by the conversion of quarks to leptons, which prevents or staves off collapse into a black ...
