  We re-examine the possibility of an astrophysically allowed KSVZ-type axion
that has a strongly suppressed coupling to photons. We then investigate the
impact of such ''hadronic axions'' on two classes of astrophysical objects:
black hole accretion disc (BHAD) based gamma-ray bursts and isolated
neutron-stars. Although our results are sensitive to details of the underlying
models, we show that hadronic axions could in principle play an important role
in the evolution of gamma-ray bursts and in the cooling behaviour of neutron
stars.
