The stage in the evolution of a star in which the pressure of the star is insufficient to maintain it at a stable size, and its material falls inward under its own gravitational attraction, eventually forming a black hole or a neutron star, and sometimes accompanied by a supernova explosion.

日本語の意味

天体（主に星）の進化過程において、内部の圧力が自分自身の重力に対抗できなくなり、物質が内向きに崩壊する現象。これにより、最終的にはブラックホールや中性子星が形成され、時には超新星爆発を伴う。

英語の意味
