当它（膨胀成红巨星、行星状星云并最后变成白矮星）死亡时，它的温度将比其他质量相近的年老白矮星，要高上许多。 - The helium will burn steadily and the higher energy production rate will heat up the star . the star will swell to a size even larger than a red giant and we have a
在恒星强大质量的约束下，核心氦聚变成碳的过程能稳定地进行，在核心高热的煎熬下，恒星外壳会极度膨胀成为比红巨星更巨大的 - Five billion years later , it will evolve along the curve to become a red giant . it will be unstable and eject the shell forming a planetary nebula , then move quickly along the curve to become white dwarf at the lower left
五十亿年之后，太阳将会演化为一颗红巨星，这个阶段的恒星十分不稳定，最终将会把外壳抛掉，形成行星状星云。 - A typical red supergiant could be about 100 times larger than the red giant . its surface temperature is low while the total luminosity remains high , with absolute magnitude up to - 10 comparing to 4 . 8 of our sun
典型的超红巨星比普通红巨星大上100倍，虽然表面温度低，但整体光度仍然非常高，绝对星等可达- 10太阳的绝对星等只有4 . 8 。 - Systems as diverse as the early universe , the interstellar medium , red giant stars , and supernova explosions are currently the focus of intense studies utilizing sophisticated computer models - models which require large quantities of nuclear data as input

当红巨星的表面引力比白矮星弱时，部分物质会盘旋流进白矮星内，当足够的物质积聚在白矮星表面，便会燃点起热核反应，产生出巨大的能量，这种爆发会维持下去，直至所有氢气耗尽。
