The Nature of the Giant Outbursts in the Bursting Pulsar GRO J1744−28
We investigate the possible role of an accretion disk instability in producing the giant outbursts seen in GRO J1744-28. Specifically, we study the global, time dependent evolution of the Lightman-Eardley instability which can develop near the inner edge of an accretion disk when the radiation pressure becomes comparable to the gas pressure. Broadly speaking, our results are compatible with earlier works by Taam \& Lin and by Lasota \& Pelat. The uniqueness of GRO J1744-28 appears to bedoi:10.1086/310167 fatcat:7o4ieaci4fffbarq7sok3hv7nm
