Abstract
Excellent coverage of the 1998 outburst of the X-ray Nova XTE J1550–564 was provided by the Rossi X-ray Timing Explorer. XTE J1550–564 exhibited an intense (6.8 Crab) flare on 1998 September 19 (UT), making it the brightest new X-ray source observed with RXTE. We present a spectral analysis utilizing 60 Proportional Counter Array spectra from 2.5–20 keV spanning 71 days, and a nearly continuous All Sky Monitor light curve. The spectra were fit to a model including multicolor blackbody disk and power-law components. XTE J1550–564 is observed in the very high, high/soft, and intermediate canonical outburst states of Black Hole X-ray Novae. Subject headings: black hole physics — stars: individual (XTE J1550-564) — X-rays: stars – 3 – 1.
