gravitational collapse

名詞

可算名詞 不可算名詞

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。

Astronomers observed the gravitational collapse of the massive star, which culminated in a brief but brilliant supernova.

天文学者たちは、その巨大な星が内部の圧力で支えられなくなり自らの重力で内側へ崩れ落ちる段階（重力崩壊）を観測し、それが短くも鮮烈な超新星爆発をもたらした。
