Abstract (from CDS):

An analysis of the high-energy emission from IGRJ16393-4643 (=AXJ1639.0-4642) is presented using data from INTEGRAL and XMM-Newton. The source is persistent in the 20-40keV band at an average flux of 5.1x10–11erg/cm2/s, with variations in intensity by at least an order of magnitude. A pulse period of 912.0±0.1 s was discovered in the ISGRI and EPIC light curves. The source spectrum is a strongly-absorbed (NH=(2.5±0.2)x1023cm–2) power law that features a high-energy cutoff above 10keV. Two iron emission lines at 6.4 and 7.1keV, an iron absorption edge >7.1keV, and a soft excess emission of 7x10–15erg/cm2/s between 0.5-2keV, are detected in the EPIC spectrum. The shape of the spectrum does not change with the pulse. Its persistence, pulsation, and spectrum place IGRJ16393-4643 among the class of heavily-absorbed HMXBs. The improved position from EPIC is RA (J2000)=16h39m05.4s and Dec=-46°42'12" (4" uncertainty) which is compatible with that of 2MASSJ16390535-4642137.
