Analysis of the 1999 Outburst of Black Hole Candidate 4U 1630-472
Abstract
4U 1630-472 is a transient low mass x-ray binary (LMXB). The lack of type I X-ray bursts in addition to characteristics in the X-ray timing and spectrum classify the compact object as a black hole candidate (BHC). This particular transient undergoes outbursts every 550 - 690 days. We analyzed archival data of this source's 1999 outburst obtained from the RXTE and USA X-ray satellites. The behavior of the disk temperature throughout the outburst is discussed along with appearance of a low frequency, ~ 1 Hz, QPO during the onset of the outburst.
