In the first seconds after a supernova, a region rich in protons emerges around the dead star ' s core, which has most likely collapsed into a neutron star
在發生超新星爆炸后的最初幾秒內,這個死亡恆星的核心(最可能塌縮形成中子星的地方)周圍,會產生一個富含質子的區域。After the supernova sn1987a exploded for more than a decade, the surrounding gas ring gradually brightened up
超新星sn1987a爆發后十多年,周圍的氣體環反而逐漸變亮。Supernova remnants : what is left after a heavy star violently explodes
超新星遺跡:超重星體爆炸后所剩下的殘跡。The crab nebula is the remnant of the supernova explosion in 1054
蟹狀星雲是1054年超新星爆發后的遺骸What will happen to the remains of the supernova explosion
恆星在超新星爆發后又如何呢?Cas a is the 300 - year - old remnant created by the supernova explosion of a massive star
仙后座a是有著300年歷史的遺跡,成因是大質量恆星的超新星爆發。In fact, the cosmic crab is now known to be a supernova remnant, an expanding cloud of debris from the death explosion of a massive star
實際上,現在我們知道蟹狀星雲是超新星爆發的遺跡,即一個巨大恆星死亡后爆炸的殘屑雲。Therefore soon after their supernova birth, their rotational speed will become so low that they stop to emit electromagnetic pulses
因此,超新星爆發后不久,磁星的自轉速度會變得非常緩慢,因而停止發放電磁脈沖。After a supernova explosion, a small but compact star, called neutron star
超新星爆炸后可能會剩下一個細小但密度很高的星球,稱為中子星In theory, the first step toward producing a millisecond pulsar is the formation of a neutron star when a massive star goes supernova
理論上,形成一顆毫秒脈沖星的第一步,是一個大質量恆星在成為超新星而爆發后留下的中子星。Nature of the universe - chapter seventeen if the remnant of a supernova explosion is heavier than two or three solar masses, the neutron degenerate pressure is not strong enough to support the star. there does not exist stronger force up to our knowledge and we believe the remnant will collapse to a black hole
在超新星爆發后,如果恆星剩餘質量超過二或三個太陽質量,中子簡並壓力亦不足以抵抗向內的引力,這時在已知的物理理論裏面,再沒有更強的力能足以與引力一決雌雄,恆星只可以不斷塌縮,成為黑洞。If the mass of the core after a supernova explosion is more than 1. 4 but less than about 3 solar masses, then electron degenerate pressure is not strong enough to support the star. the star will contract to a size even smaller than the white dwarf. the electrons are squeezed into the nuclei and are combined with the protons to form neutrons
假若在超新星爆發后,剩餘核心質量介乎太陽質量的1 . 4至3倍,那麼核心中的電子簡並壓力便再不足以抵抗強大的引力,恆星會進一步收縮,直至電子亦被擠壓至原子核內,和質子結合成為中子。Higher mass stars will die in spectacular stellar explosions called supernovae, leaving behind even more compact objects - neutron stars for stars of mass lower than 25 solar masses and black holes for stars of mass higher than 25 solar masses
一些質量大於8個太陽質量但少於25個太陽質量的恆星在超新星爆發后會成為中子星,而質量大於25個太陽質量的恆星最終會演化成黑洞。分享友人
