What is a yellow giant star?Space and Astronomy
Giant stars with intermediate temperatures (spectral class G, F, and at least some A) are called yellow giants. They are far less numerous than red giants, partly because they only form from stars with somewhat higher masses, and partly because they spend less time in that phase of their lives.
How common are yellow giant stars?
Yellow giant stars are rare
Compared to the high numbers of main sequence and red supergiant stars, yellow giant stars are exceedingly rare. This is evident from the fact that a recent study identified only 16 yellow giant stars in a region of M31 (Andromeda galaxy) that contained more than 25,000 O-type stars.

Why are yellow Hypergiants so rare?
These stars are doubly rare because they are very massive, initially hot class O-type main-sequence stars more than 15 times as massive as the Sun, but also because they spend only a few thousand years in the unstable yellow void phase of their lives.

What is the difference between a giant star and a supergiant star?
What is the difference between a giant star and a supergiant star? Giant stars have radii between 10 and 100 solar radii and luminosities between 10 and 1,000 times that of the Sun. Whereas Supergiants have radii between 30 and 1,000 solar radii and luminosities between 30,000 and 100,000 times that of the Sun.
