Fusion of Stars: Time Difference for 0.50 & 1.5 Msolar Stars

[blumfeld0]

How many times longer does a 0.50 Msolar star fuse hydrogen at it’s core than dose a 1.5 Msolar star?

i just need the equation and i can figure it out. i can't find anything on google

thank you

I take it that you're on some sort of astronomy course and this is homework? The equation you are looking for can be easily derived by cosidering the fractions of mass that a star converts to energy and the luminocity of the star then comparing that with the values for our own star.
