Recent studies of photon-generation mechanisms in the color-superconductingColor-Flavor Locked (CFL) phase of dense quark matter have found gamma-rayemissivities in excess of ~ 10^{50} erg cm^{-3} s^{-1} for temperatures in the10-30 MeV range. We suggest that this property can trigger gamma-ray bursts(GRBs) and associated fireballs at the surface of hypothetical hot (newly born)quark stars with an energy release of up to 10^{48}-10^{50} erg within afraction of a millisecond. If surrounded by an accretion disk following itsformation, the star's bursting activity can last from tens of milliseconds tohundreds of seconds releasing up to 10^{52} erg in total energy. We discusstypical features of observed GRBs within our model and explain how quark starsin the CFL phase might constitute natural candidates for corresponding innerengines.Comment: 8 journal pages, 6 figures.
