Explanation:
Detailed explanation-1: -How long a main sequence star lives depends on how massive it is. A higher-mass star may have more material, but it burns through it faster due to higher core temperatures caused by greater gravitational forces.
Detailed explanation-2: -Mass limits of Main Seqence stars—At the low end, this is set by the amount of mass whose gravitational collapse will heat up the core to a sufficiently high temperature to begin nuclear “burning". This is theoretically known to be 0.08 solar masses, or about 80 times the mass of Jupiter.
