What is the life expectance of a 16-solar mass star?

Question

please help, and show me where it can be found for future reference please. thanks!

Answer 1

Massive stars in the10 to 20 solar mass range burn up all their fuel and explode in about 10 million years.

  A1 solar mass star will never explode and it has a life expectancy of about 10 billion years.

Answer 2

9 million years if I did my math right-->

Answer 3

A 16.0 solar mass star would spend about 11.7 million years on the main sequence (depending on the metallicity).  After approximately 13.0 million years it would become a 1.5 solar mass (approx.) neutron star.  This was calculated using metallicity z=0.02 (solar)

For those of you who don't know...

The amount of metal in a star determines its metallicity.  Stars that were formed closer to the big bang will not have as high of metal content as stars that have formed more recently (since metals are created in stars and supernova explosions)
