Sentence examples for collapse of a star from inspiring English sources

I've read that the final core collapse of a star happens within less than a second.

It was that pulsars are rotating neutron stars, the super-dense last stage of collapse of a star not quite heavy enough to form a black hole.

A neutron star – small but extremely dense – is formed by the gravitational collapse of a star not quite massive enough to produce a black hole when it explodes.

At the time of the final core collapse of a star, the core itself is only about the size of Earth, and it contracts to something approximately sixteen kilometers across (diameter).

It has been deduced that so-called black holes in space may occur in places where extraordinarily massive or dense aggregates of matter exist, as in the gravitational collapse of a star.

This solution is however completely unphysical in many ways and in a real Black Hole (formed from the collapse of a star for example) we cannot use the vacuum solution as there is matter present, and the White Hole singularity disappears.

Gamma-ray bursts (GRB) are brief intense flashes of gamma-rays that are produced when a relativistic jet is launched after the collapse of a massive star or after a neutron star-neutron star merger or neutron star-black hole merger.

Numerous other models have also been proposed to explain short gamma-ray bursts, including the merger of a neutron star and a black hole, the accretion-induced collapse of a neutron star, or the evaporation of primordial black holes.

Long bursts are believed to be related to the collapse of a massive star, while short bursts are believed to be related to the collision of two neutron stars or a neutron star and a black hole.

No one is certain what causes them, but the leading theories are a hypernova the sudden collapse of a massive star to form a black hole or a collision between two neutron stars, the ultra-dense remnants of supernovas (slightly less massive collapsed stars).

Type II supernovas arise from the collapse of a single star more massive than about eight solar masses, resulting in either a neutron star or black hole.
