exotic stellar atmospheres

AA stars, kaon stars and black holes.

Of course, black holes don't have a surface so they cannot have an
"atmosphere" as one usually thinks of it. As for neutron stars, there
is an extensive literature. For instance, typing in "neutron star
atmosphere" at the ADS finds over 350 hits.

Indeed, it looks like there are claims of direct detection of a
neutron star atmosphere in 1E 1207.4-5209 via X-ray absorption
features (Sanwal et al. 2002ApJ...574L..61S, URL:
