WebStars larger than red dwarfs do this by increasing their size and becoming red giants with larger surface areas. Rather than expanding, however, red dwarfs with less than 0.25 solar masses are predicted to increase their radiative rate by increasing their surface temperatures and becoming "bluer". This is because the surface layers of red ... WebVery low-mass stars never become red giants. Once they have depleted their supply of hydrogen, they become helium white dwarfs and gradually cool. Low-mass stars do evolve into red giants when they exhaust the hydrogen in their cores. They end their lives by ejecting their outer shells as planetary nebulae, leaving behind white dwarfs.

After a red giant has shed all its atmosphere, only the core remains. Scientists call this kind of stellar remnant a white dwarf. A white dwarf is usually Earth-size but hundreds of thousands of times more massive. A teaspoon of its material would weigh more than a pickup truck.

"WebThe track for a 1-solar-mass star shows that the Sun is still in the main-sequence phase of evolution, since it is only about 4.5 billion years old. It will be billions of years before the Sun begins its own “climb” away from the main sequence—the expansion of its outer layers that will make it a red giant. " - Do red giants become white dwarfs
