Pair-instability supernova

  • 不稳定对超新星(正负电子对产生时,会减弱超巨星核心内部的热压力,导致局部崩溃,进而引发热核爆炸,将恒星完全吹散,无需留下黑洞残骸)

Pair-instability supernova

  • abstract: This illustration explains the pair-instability supernova process that astronomers think triggered the explosion in SN 2006gy. When a star is very massive, the [[gamma-rays produced in its core can become so energetic that some of their energy is drained away into production of particle and anti-particle pairs.

  • Before the findings, most astronomers had argued that gigantic stars in nearby galaxies slough off much of their mass before dying out, precluding a pair-instability supernova.

    这些发现之前多数天文学家一直争论银河系附近巨星消亡前,抛弃了其大部分质量,这样就无法形成对不稳定超新星。

  • The cycle can repeat itself in pulses—astronomers call this case a “pulsational” pair-instability supernovauntil the star loses enough mass to end its life in an ordinary supernova.

    这个过程可能周而复始,周期性地重复--天文学家称之为"脉动"对不稳定性超新星--直至恒星失去足够的物质普通超新星的形态中走生命的尽头。

  • For decades astronomers have suspected the existence of a type of stellar explosion that is bigger still-a "pair-instability" supernova, with 100 times more energy than an ordinary supernova.

    数十年来,文学家们一度怀疑寂静恒星爆炸存在——称之为“对不稳定”超新星,其能量超过普通超新星100
