Which of the following stars would be most likely to have the same abundance of elements heavier than helium as a red main sequence star in globular cluster M13?
A) None of these choices
B) Red giant in globular cluster M13
C) A red main sequence star in the disk of the Milky Way

Quizplus · Accepted Answer

Both red giants and red main sequence stars in globular clusters have similar abundances of elements heavier than helium due to their formation in chemically enriched environments. On the other hand, red main sequence stars in the disk of the Milky Way have a higher abundance of heavy elements due to their formation in a region with higher metallicity. Therefore, the most likely choice to have the same abundance of elements heavier than helium as a red main sequence star in globular cluster M13 would be a red giant in the same cluster.
