Information entropy applied to compact stars

 

Marcio Avellar (IAG/USP)

 

We used the statistical measurements of information entropy, disequilibrium and complexity to infer a hierarchy of equations of state for two types of compact stars from the broad class of neutron stars, namely, with hadronic composition and with strange quark composition. Our results show that, since order costs energy, Nature would favour the exotic strange stars even though the question of how to form the strange stars cannot be answered within this approach.
