Is anyone here familiar with the Vaidya/Lemaitre-Tolman metrics? Wiki claims that they're both used to model radiating spherically symmetric dust, but I'm not so sure after grinding out the curvature tensors, etc.
tl;dr a spherical star is ejecting a spherical shell of dust - what metric do I use (short of brute forcing a new solution)?
Let's see if you can still do this. \bbox["><span id="xyzzy" onmouseover="
