Abstract

IGR J19140+0951 (formerly known as IGR J19140+098) was discovered with the INTEGRALsatellite in March 2003. We report the details of the discovery, using an improved position for the analysis. We have performed a simultaneous study of the 5–100 keV JEM-X and ISGRI spectra from which we can distinguish two different states. From the results of our analysis we propose that IGR J19140+0951 is a persistent Galactic X-ray binary, probably hosting a neutron star although a black hole cannot be completely ruled out.
