Question

Compared with our sun, how would you describe stars in the galactic halo?group of answer choices

O young, blue, bright, and metal-rich
O old, red, dim, and metal-poor

Answer 1

Stars in the galactic halo are old, red, dim, and metal-poor, known as Population II stars, whereas our Sun is a younger, metal-rich Population I star.

Step-by-step explanation:

Compared with our Sun, stars in the galactic halo are described as old, red, dim, and metal-poor. These characteristics align with what is known as Population II stars, which are typically found in the halo and in globular clusters.

Our Sun, in contrast, is a Population I star, being younger, found in the disk of the galaxy, particularly concentrated in the spiral arms, and richer in metals. Population I stars are formed from the interstellar medium that has been enriched with heavy elements by previous generations of stars. The stars in the galactic halo, with highly elliptical orbits, spend most of their time far away from the galactic plane, contrasting with the sun which resides relatively close within the galactic disk.
