Spectral analysis of the low-mass X-ray pulsar 4U 1822-371: Reflection component in a high-inclination system
A. Anitra, T. Di Salvo, R. Iaria +6
The X-ray source 4U 1822-371 is an eclipsing low-mass X-ray binary and X-ray pulsar, hosting a NS that shows periodic pulsations in the X-ray band. The inclination angle of the sys…
Fe K and Fe K line detection in the NuSTAR spectrum of the ultra-bright Z-source Scorpius X-1
S. M. Mazzola, R. Iaria, T. Di Salvo +8
Low-mass X-ray binaries hosting a low-magnetised neutron star, which accretes matter via Roche-lobe overflow, are generally grouped in two classes, named Atoll and Z sources after…
Evidence of a non-conservative mass transfer in the ultra-compact X-ray source XB 1916-053
R. Iaria, A. Sanna, T. Di Salvo +5
The dipping source XB 1916-053 is a compact binary system with an orbital period of 50 min harboring a neutron star. Using ten new {\it Chandra} observations and one {\it Swift/XRT…
Reflection component in the Bright Atoll Source GX 9+9
R. Iaria, S. M. Mazzola, T. Di Salvo +5
GX 9+9 (4U 1728-16) is a low mass X-ray binary (LMXB) source harboring a neutron star. Although it belongs to the subclass of the bright Atoll sources together with GX 9+1, GX 3+1,…
