University of Copenhagen astrophysicists help explain a mysterious phenomenon, whereby stars suddenly vanish from the night sky.
Stellar collapse: Why stars sometimes vanish from our skies
The findings suggest that a star's gravitational pull can be so strong that it collapses into a black hole without an explosion. “We believe ...
Gravitational collapse - Wikipedia
The star then exists in a state of dynamic equilibrium. During the star's evolution a star might collapse again and reach several new states of equilibrium.
