Glossary term: 中子星

Description: 中子星是一個非常密集和緊湊的恆星殘骸,形成於大質量恆星核心的坍塌。質量約為八倍太陽質量或更多的恆星在其恆星演化的最後,核心會坍塌,觸發超新星爆炸。坍塌的核心密度大於大多數原子核,並主要由中子組成。這一點的原因是,在大質量恆星極熱和極密的坍塌核心中,質子和電子結合形成中子。中子星的下限質量為1.4倍太陽質量,上限約為3倍太陽質量——超過這個質量,物體將坍塌為黑洞。高度磁化的中子星被稱為磁星。已知的絕大多數中子星以射電脈衝星的形式被觀測到。

Death of a massive star

Caption: A multi-wavelength image taken with telescopes on the Earth and in space of a neutron star within our neighbouring Small Magellanic Cloud galaxy. A neutron star (seen here as the blue spot surrounded by a red ring) is the final product of gravitational collapse, compression and explosion of a massive star, left embedded in its supernova remnant (in green).
