Homework Statement
I have to calculate the lifetime of a star that is 300,000 times as luminous as the sun and 24 solar masses.
Homework Equations
lifetime = k * m/l
The Attempt at a Solution
lifetime = 10^10 * (24/300000)
lifetime = 800000 years
I feel as if this is almost too easy and am wondering if I have made an error along the way. In addition, I found this equation on the internet and don't really understand how it works despite knowing (or thinking I know) how to use it. I was hoping someone could explain it to me and if I am wrong, someone could point me in the right direction.
Many Thanks
John
