RXTE ASM finds the Rapid Burster (MXB1730-335) at a Nearly Constant Elevated Intensity
Abstract
Over the 13 years of monitoring of MXB1730-335 (the Rapid Burster; ASM catalog entry x1730-333) by the RXTE ASM, the source has most often been seen at low intensities, i.e., below 10 mcrab. This low intensity state is punctuated by outbursts which generally have a fast rise to a peak intensity of 100 mcrab (1.5-12 keV) or more and a roughly exponential decay over 2 to 4 weeks. The outbursts have occurred quasiperiodically at intervals of 100 to 200 or so days.
