One question, Tan says, is how efficiently the process works for massive versus light stars, because that's likely to be the mechanism that determines stellar mass.

有个问题，谭说，在巨型与小恒星间，谁的形成机制更有效，因为那可能是确定星际物质形成机制。

The strength of the absorption features indicates that red dwarfs account for 80 percent of the number of stars in elliptical galaxies and 60 percent of the total stellar mass in those galaxies.

吸收特性的力度显示，红矮星数量约占椭圆星系星量的百分之八十，质量则是那些星系总质量的百分之六十。

This was based on the assumption that SMBHs form in a similar way to stellar-mass black holes, marking the final phase in the lifespan of massive stars that have exhausted all their fuel for fusion.

这是以大多超大质量黑洞形成过程与恒星质量的黑洞的形成过程类似的假设为基础的。 这种黑洞的形成通常在大质量恒星的生命过程的最终阶段（用尽了用于核聚变的所有燃料的时期）。

Those unseen and isolated stellar mass black holes that could lie almost as close as the nearest stars.

Black holes are known to exist in two classes: The stellar variety result from exploded massive stars and typically pack the mass of a few stars.
