WebThe maximum mass that a star can end its life with and still become a white dwarf— M Sun —is called the Chandrasekhar limit.

A star’s main sequence lifetime is determined by the balance of forces acting on it. The star’s own gravity pulls it inward, while the pressure created by the star’s nuclear fusion reaction pushes outward. The heavier the star, the more gravity it has pulling inward, and the shorter its main sequence lifetime. can a jeep gladiator tow a camper
