The behavior of pions is studied in systems where their normal leptonic decay
is forbidden. When thermal fluctuations are present, a low decay rate is
generated, and as a consequence of lepton recombination, the amount of pions
remains almost unaltered. Compact stars conditions are favorable for the
formation of such intermediate state of charged pions: near condensation and
almost stable, leading to a continuum source of anti-neutrinos. In particular,
protoneutron stars could be an scenario where this state of matter is relevant.
