hey,
thought i would throw this problem out there...
if you have the luminosity of a red supergiant 400,000 times more luminous than the sun and a mass of 30 times greater than the sun how would you go about answering how much longer or shorter than the sun would you expect it to liv?
i know luminosity is related to mass but i don't have any actual figures and I am contemplating looking for the circumference /radius and using that.
any smarter thoughts?!?
cheers!
