L = 4\pi R^2 \sigma T^4

Luminosity of a star from radius and temperature.

b = \frac{L}{4\pi d^2}

Observed brightness from luminosity and distance.

\frac{L}{L_\odot} \approx \left(\frac{M}{M_\odot}\right)^{3.5}

How a main-sequence star's brightness scales with its mass.

L_{Edd} = \frac{4\pi G M m_p c}{\sigma_T}

The maximum steady luminosity before radiation blows a star apart.
