solar mass

Astronomers tried to estimate what solar mass could produce the required luminosity to explain liquid water on these planets.

天文学家试图通过估计太阳质量能产生多少必需的光来解释这些行星上的液态水。

All the mass measurements that have been done to date of these neutron stars where you see the pulsations... all of them are very close to 1.4 solar mass.

对于这些中子星的，质量测量，你看到脉冲，所有的都很接近于。，1。4倍的太阳质量，对此有个很好的解释。

So, by not collapsing into denser regions, these massive nebulae, like the 100,000 solar mass California Nebula shown above, don't necessarily start making baby stars and planets.

所以如果不被压缩到很致密，这些大质量星云，比如有太阳质量100，000倍的California星云，则不一定会形成新生恒星和行星。
