Calculate the main sequence lifetime of a star of 1.7 solar masses and a luminosity 5 times that of the Sun if the Sun`s main sequence lifetime is 10^10 years and its luminosity has been constant.
Added by Michael P.
Step 1
We know that the main sequence lifetime of the Sun is 10^10 years and its luminosity is constant. This means that the Sun will remain on the main sequence for 10^10 years before evolving into a red giant. Show more…

Calculate the main-sequence lifetimes of (a) a 9 $M_{odot}$ star, and (b) a 0.25 $M_{odot}$ star. Express the lifetimes of these stars as multiples of the Sun's lifetime ($ au_{odot} = 10^{10}$ years), as well as in units of years.
