  Axion physics has received a boost with the recent claim of the PVLAS
collaboration. Their results can be interpreted as due to a new axionlike
particle but the CAST collaboration has not found trace of it. While the
axionlike particle interpretation of the PVLAS signal is going to be probed by
dedicated laboratory experiments, it is mandatory to find either alternatives
to it or models in which the astrophysical bounds could be evaded. In this
communication one of such models is presented. The new physics involved appears
at a low energy scale $<$ eV.
