Hi everyone,
I am currently looking to calculate the amount of stars that die within a certain time-frame. I am trying to go about this using the Salpeter IMF to figure the distribution of star masses...
∫M⋅Φ(M)dM
From here I would need to use star mass to calculate the lifetime of stars as a function of mass...t(M). Then using this I would apply it somehow to the distribution to find out how many of those stars die for a given time (t +Δt).
Is this the right train of thought?
Thanks in advance!
Edit:
Thinking about this more, I could also find the mass turnoff point at that time. From this can't I calculate how many stars are above that mass? That would give me how many stars have died up to that time? If this is all true, it must be difficult to make this a generalized formula...thoughts?
