Most medium mass stars such as our Sun DO become red giants.
Smaller stars do not have enough mass to initiate helium fusion when the hydrogen supply begins to run low, and do not become red giants.
i dont know
No. Only massive stars can become supergiants.
Not exactly. Red giants become white dwarf stars. It is the red supergiants that can become supernovas.
Stars become red giants when they have exhausted their hydrogen fuel in the core and start burning helium, causing the outer layers to expand and cool. This expansion turns the star into a large, cool, and luminous red giant.
No, red giant stars are not the largest stars in the universe. There are stars known as supergiant and hypergiant stars that are even larger than red giants. These stars can be hundreds to thousands of times larger than our Sun.
No. Intermediate mass stars will evolve into Red Giants and then to White Dwarfs. See related questions for more information.
Stars expand in size to become red giants, when they start running low on Hydrogen fuel.
No, they are mostly red dwarf stars.
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
If they have red stars including giants in, they can't be all that featureless.
All stars eventually turn into Red Giants or Super Giants
Red Giants are stars that have become larger throughout millions of years and are about to blast and become tiny white drawfs. Our sun after millions of years will become a red giant it self and when it does we won't be alive because it will be so hot and much more closer to the Earth then it is right now.
