Explanation:

Question 7

Main - sequence stars do span a large range of luminosities (from very low - luminosity red dwarfs to high - luminosity blue giants) and colors (related to their surface temperatures). They are classified based on these characteristics (e.g., using the Hertzsprung - Russell diagram).

Main - sequence stars with a mass of more than about 8 solar masses are massive enough to undergo the core - collapse supernova process at the end of their lives.

According to the Oppenheimer - Volkoff limit, if the collapsed stellar core (after a supernova explosion for a massive star) has a mass greater than approximately 3 solar masses, it will collapse completely to form a black hole.

Answer:

True
