0.8 to 8 Times the Sun’s Mass

Stars of intermediate mass have lifetimes that range between 50 million and 20 billion years.  Nuclear reactions in these stars make most of the carbon and nitrogen in the universe.  When intermediate-mass stars die, they blow off their atmospheres, dispersing such elements across space.
