Query: Finite Temperature Effects and Axion Cosmology   We investigate the impact of finite temperature effects on axions in the
context of cosmology. The temperature dependence of the decay constant is
modeled analogous to pions. For the two interesting cases considered here, we
find that the temperature effects do lead to changes relevant for detailed and
precise abundance and rate calculations. We also find that the axion decoupling
temperature starts showing large deviations for larger values of the axion
decay constant.
