### How can the upper limit for a star's mass be calculated?

I know there is a theoretical mass limit for stars around $300 M_\odot$. But I cannot find a way to calculate that number. I tried to use the "Eddington Limit", but I don't know if I'm on ...

### What is an actual value for the Eddington pulsation constant?

What numerical value does the pulsation constant $Q$ take in the formula that Eddington derived for variable stars: $$P\sqrt{\rho} = Q,$$ where $\rho$ — average star density, $P$ — period?

### How does the Eddington limit make the gravitational field of stars asymmetric?

This answer to Is the gravitational field of the sun uniform? says: Very large stars are asymmetric due to being close to the Eddington limit. The Sun is too small of a star to have the kind of ...

### Formation of the First Stars

I've got a few questions about the first stars to form in the universe. First off how might metalicity have impacted the formation of the first stars and also what effect would the absence of metals ...

We know Eddington Limit (Eddington Luminosity) is calculated with this formula: $$L_{Ed} \approx 3 * 10^4 * L_{sun} * \frac{M}{M_{sun}}$$ Example: For a black hole with $10^4 M_{sun}$, we get L_{...
