How are red giants formed
WebPlanetary nebulae seem to mark the transition of a medium mass star from red giant to white dwarf. Stars that are comparable in mass to our Sun will become white dwarfs within 75,000 years of blowing off their envelopes. Eventually they, like our Sun, will cool down, radiating heat into space and fading into black lumps of carbon. WebSupergiants have the largest radius of all known stars. They evolve from large main-sequence stars. Supergiants can contain 8 - 200 times the mass of the Sun! They also …
