supernova star的意思|示意

The cycle can repeat itself in pulses—astronomers call this case a “pulsational” pair-instability supernova—until 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，在普通超新星的形态中走到生命的尽头。

For the first time ever, a black hole has been seen being born out of a supernova of a star perhaps 20 times the mass of our sun.

有史以来，人类第一次观察到了一个黑洞的诞生，它生成自一颗约是太阳质量20倍恒星的超新星爆炸中。

At this point the pressure at its center will become so great that runaway fusion occurs and the star will detonate in a thermonuclear supernova.

在这个极限点上，其中心压力将变得如此巨大，以至于爆发失控的核聚变，而恒星则爆炸成为热核爆炸型超新星。
