Chandra Observations of the M31 X-Ray Transient SWIFT J004320.5+411528
Abstract
As part of our ongoing Chandra/HST M31 transient program we report on a Chandra ACIS observation of M31 containing the new transient source reported by Pietsch et al. (2008, ATel #1674). A single 5ks observation was performed on 2008-09-01.32 UT. The Chandra coordinates for this source (subject to the boresight correction) are RA(J2000) 00:43:20.710, Dec(J2000) +41:15:31.31. Although we cannot rule out an absorbed power law, an absorbed disk black body with nH = 8.4e20 atoms/cm2 and Tin = 0.7 keV represents the best physically motivated model that fits the data.
