The unusual hard x-ray burster GRO J1744-28 recently discovered by the
Compton Gamma-Ray Observatory can be modeled as a strange star with a
dipolar magnetic field of less than or equal to 10(11) gauss. Accordi
ng to this model, when the accreted mass of the star exceeds some crit
ical mass, its crust breaks, resulting in the conversion of the accret
ed matter into strange matter and a release of energy. Subsequently, a
fireball forms and expands relativistically outward. The expanding fi
reball interacts with the surrounding interstellar medium, causing its
kinetic energy to be radiated in shock waves and producing a burst of
x-ray radiation. The burst energy, duration, interval, and spectrum d
erived from such a model are consistent with the observations of GRO J
1744-28.
