Compare and contrast the life of a star that has a mass the of a star that has a mass similar to our Sun with the life of a star more massive than our Sun.

Helloyo!

Massive Star

They are typically greater then 8 molar masses. They typically have a quick main sequence phase, a short red supergiant phase and a death of a spectacular Cosmic event: Supernova. From there they can either become Neutron Stars or Black Holes

Medium-Sized Star

They usually have a Normal Main Sequence phase (Billions of years). From there they bevome Red Giants and expell their mass in a planetary nebula. From there they shrink and become white dwarfs first, then black dwarfs.

Hope it helps ya

...though astronomy is actually physics btw...
