n. (context star English) The black hole thought to form following the gravitational collapse of a massive star
Wikipedia
Collapsar is the shortened form to describe a collapsed star. When an old star no longer has enough fuel for significant fusion reactions there can be three possible outcomes depending on the star's mass. If the star’s mass is less than 1.4 solar masses, known as the Chandrasekhar limit, it will stabilize and shrink, becoming a white dwarf. Above the said limit the star will either become a neutron star or a black hole.
Collapsar may also refer to:
- Collapsar model for a Hypernova
Usage examples of "collapsar".
The collapsar, vibrating, behaved not like a perfectly elastic ball but, rather, like a nonuniformly distorting balloon on a bounce, due to the magnification of relativistic effects.

The astrophysicists ignored this rumor: no kind of radar could have detected the ship near the collapsar.
But any noncatastrophic passage past the collapsar had low probability.
Even such a globe the collapsar would pull out into a spindle shape, and would tear and swallow it in an instant, leaving behind only the death-throe flares of X rays escaping into space.

Ejected previously into space far from the collapsar, cameras took pictures of the planet, using no little aperture: two astronomical units.
The Hermes, having climbed above the ecliptic, plummeted like a stone toward Hades, initially retreating from the star of its destination in order to reach it more easily, at the gravitational cost of the collapsar: circling the collapsar, it received from its field a hefty push.
