		| Abstract: | 
		Regarding quantitative theory, this object is surprisingly unexplored despite a wealth of modern observations; we do not truly understand its behavior on any timescale from a week to a millennium. The rotational and thermal structures may be far from equilibrium. Here I sketch a number of unsolved problems, potentially significant for stellar astrophysics in general, concerning its interior structure. |
