The enhanced X-ray Timing and Polarimetry mission - eXTP
ShuangNan Zhang, Andrea Santangelo, Marco Feroci +146
In this paper we present the enhanced X-ray Timing and Polarimetry mission - eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of…
X-ray and optical monitoring of the December 2017 outburst of the Be/X-ray binary AX J0049.4-7323
L. Ducci, C. Malacaria, P. Romano +5
AX J0049.4-7323 is a Be/X-ray binary that shows an unusual and poorly understood optical variability that consists of periodic and bright optical outbursts, simultaneous with X-ray…
Spectral and timing analysis of the bursting pulsar GRO J1744-28 with RXTE observations
Long Ji, Andrea Santangelo, Shu Zhang +5
We analyzed RXTE/PCA observations of the bursting pulsar GRO J1744-28 during its two outbursts in 1995-1997. We have found a significant transition, i.e., a sharp change, of both s…
NuSTAR and NICER reveal IGR J17591-2342 as a new accreting millisecond X-ray pulsar
A. Sanna, C. Ferrigno, P. S. Ray +21
We report on the discovery by the Nuclear Spectroscopic Telescope Array (NuSTAR) and the Neutron Star Interior Composition Explorer (NICER) of the accreting millisecond X-ray pulsa…
The magnetospheric radius of an inclined rotator in the magnetically threaded disk model
E. Bozzo, S. Ascenzi, L. Ducci +3
The estimate of the magnetospheric radius in a disk-fed neutron star X-ray binary is a long standing problem in high energy Astrophysics. We review the magnetospheric radius calcul…
In-depth study of long-term variability in the X-ray emission of the Be/X-ray binary system AX J0049.4-7323
L. Ducci, P. Romano, C. Malacaria +3
AX J0049.4-7323 is a Be/X-ray binary in the Small Magellanic Cloud hosting a ~750 s pulsar which has been observed over the last ~17 years by several X-ray telescopes. Despite nume…
