Strömgren integral

In mathematics and astrophysics, the Strömgren integral, introduced by while computing the Rosseland mean opacity, is the integral:


 * $$ \frac{15}{4\pi^4}\int_0^x \frac{t^7e^{2t}}{(e^t-1)^3} \, dt .$$

discussed applications of the Strömgren integral in astrophysics, and discussed how to compute it.
