How do we measure stellar masses quizlet
WebFigure 1.3 Stellar Corpse. We observe the remains of a star that was seen to explode in our skies in 1054 (and was, briefly, bright enough to be visible during the daytime). Today, the remnant is called the Crab Nebula and its central region is seen here. http://hyperphysics.phy-astr.gsu.edu/hbase/Astro/startime.html
