Question

In the context of astrophysics, what significance does the notation "M < 0.5 < 4 solar mass" have?

A) It represents a political ideology.
B) It indicates a social class in the solar system.
C) It defines the mass range for stars where fusion reactions can occur.
D) It describes a historical event related to space exploration.

Answer 1

The notation 'M < 0.5 < 4 solar mass' represents the mass range for stars where fusion reactions can occur.

Step-by-step explanation:

In the context of astrophysics, the notation 'M < 0.5 < 4 solar mass' refers to the mass range for stars where fusion reactions can occur. This notation indicates that the mass of a star should be less than 0.5 times the mass of the Sun, but greater than 4 times the mass of the Sun, in order for fusion reactions to take place.
