      abstract     = {Several stellar systems (white dwarfs, red giants,
                      horizontal branch stars and possibly the neutron star in the
                      supernova remnant Cassiopeia A) show a preference for a mild
                      non-standard cooling mechanism when compared with
                      theoretical models. This exotic cooling could be provided by
                      Weakly Interacting Slim Particles (WISPs), produced in the
                      hot cores and abandoning the star unimpeded, contributing
                      directly to the energy loss. Taken individually, these
                      excesses do not show a strong statistical weight. However,
                      if one mechanism could consistently explain several of them,
                      the hint could be significant. We analyze the hints in terms
                      of neutrino anomalous magnetic moments, minicharged
                      particles, hidden photons and axion-like particles (ALPs).
                      Among them, the ALP represents the best solution.
                      Interestingly, the hinted ALP parameter space is accessible
                      to the next generation proposed ALP searches, such as ALPS
                      II and IAXO.},
