Stellar polytropes and Tsallis' entropy
Abstract
It is shown that recourse to Tsallis' generalized entropy makes it possible to find sensible distribution functions for stellar polytropes, while that of Boltzmann yields unphysical distributions. Additionally, some constraints are imposed on Tsallis' entropy.
