> Larger stars like the Sun show a mix of radiative transfer – photons being absorbed and reabsorbed as they make their way to the surface – and convection.

> That enhances M-dwarf flare activity as their plasma is twisted and rotated, producing magnetic fields that snap open only to reconnect.

This is the first post I've seen targeted toward generic geeks that explained it that way. It makes total sense, is really cool, and I'm glad they wrote this article.
