Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have a question from the Dutch Astrophysics Olympiad, which I can't solve.

" Is there mathematical proof that stars are still being formed? "

In previous questions, i had to derive the following equations, which i need to use in my answer for the question above:

L = σ * T^{4}* 4πR^{2}

(Luminosity-Temperature relation of a star, where σ is the Boltzmann constant, T is temperature and R is the radius of the star)

t = life time of sun * (M/Msun)^{-2,6}

(where t equals the life time of a type V star and M equals mass)

Can anyone help me with this?

Thanks,

Max.Planck
