exotic stellar atmospheres

I'm under the impression that all stars have stellar atmospheres,
although in the case of dense objects like neutron stars the thickness
of the atmosphere might be very small. What I would like to know is
what the composition of the stellar atmosphere is in the case of various
kinds of collapsed stars, such as neutron stars, kaon stars and black holes.
Naturally, I don't expect anyone really to know in some of these cases where
there is no experimental evidence, but in those cases I'd like to know what
theory predicts for the composition of the stellar atmosphere.

If you know of literature on this topic, please let me know.

Ignorantly,
Allan Adler
