increases so as to maintain pressure equilibrium. This results in an increasing rate of energy production, which in turn causes the luminosity of the star to increase. The lifetime of the core hydrogen-fusing phase decreases with increasing stellar mass. For a star with the mass of the Sun, this period is around ten billion years. At the lifetime is 65 million years while at the core hydrogen-fusing period is only six million years. The longest-lived stars are fully convective red dwarfs, which can stay on the main sequence for hundreds
