Question

Distinguish between spiral and elliptical galaxies in terms of the presence or absence of a disk component and halo component. How does this difference explain the lack of hot, young stars in elliptical galaxies?

Answer 1

Answer:

lack a significant disk component, although both types have the halo component.

Explanation:

• The absence of the disk components in the elliptical galaxies is a major difference that occurs in the spiral and the elliptical as the elliptical galaxies lacks disk components they would not have an active star formation taking place.

• As the halo does not have that star formation properties and are small in nature and thus have much older stars than in spiral galaxies.
