Time-average Broadband Spectra of Dipping LMXB Sources Observed with INTEGRAL
Abstract
The X-ray observations have revealed that many microquasars and low-mass X-ray binaries LMXBs exhibit narrow absorption features identified with resonant absorption from and iron and other abundant ions XMM-Newton observations have shown that at moderate spectral resolution these features blend together modifying the observed 1--10 keV continuum We present the time-averaged INTEGRAL broadband spectra of the LMXB dipping sources 4U 1916-053 4U 1323-62 4U 1624-49 and 4U 1746-37 We discuss the nature of the comptonizing regions in these systems We find that the broadband spectra can be well modeled if the effects of a highly photo-ionized plasma are also included
