Answer:
After its main Sequence existence a medium sized star like our sun becomes a red giant.
Explanation:
A red giant star is a large reddish star whose mass ranges from about 0.3 to 8 times the mass of our sun. Red giants are stars that are already at an advanced stage of their “life”. .
At this stage, due to the fusion of hydrogen into helium in the outer layers, these same layers eventually expand into a red giant. At this stage the star has already left the so-called main sequence.
A red giant star has a diameter of a few dozen, or even hundreds of times the diameter of our sun. However, the limits of this star are not well defined due to the low density of the outer layers.
The surface temperature of a red giant is relatively low, usually no more than 5,000 K.
Later, the red giant star eventually expels its outer layers, forming what we call the planetary nebula. Meanwhile the red giant's core remains cohesive by its own force of gravity. This nucleus that remains of the red giant becomes a white dwarf, a small but very dense star.
Examples of red giant stars: Aldebaran and Arcturus.
The layers of the sun, ranked from greatest to least distance from the sun's center, are: core, radiative zone, convective zone, photosphere, chromosphere, transition region, and corona.
