I need to figure out the solar masses! Thank you!
According to stellar theories & observations the average lifetime of main-sequence stars has usual lifetime of upto few billion years.
the characteristic time scale for main sequence (MS) stars:
the main sequence stars usually have lifetime of few Billion years.
we can compute the main sequence time scale by comparing it will solar time scales.
