A Detailed Spectral Study of Intermittent-Accreting Millisecond X-ray Pulsar Aql X-1 during Pulse-on and Pulse-off Stages
T. Kocabıyık, C. Güngör, M. T. Sağlam +2
We present a detailed spectral study of an intermittent-AMXP Aql X-1 during the pulse-on and pulse-off stages by using the archival RXTE data. We first perform temporal analysis by…
The evolution of the broadband temporal features observed in the black-hole transient MAXI J1820+070 with Insight-HXMT
Yanan Wang, Long Ji, S. N. Zhang +117
We study the evolution of the temporal properties of MAXI 1820+070 during the 2018 outburst in its hard state from MJD 58190 to 58289 with Insight-HXMT in a broad energy band 1-150…
Diagnostic of the spectral properties of Aquila X-1 by Insight-HXMT snapshots during the early propeller phase
C. Güngör, M. Y. Ge, S. Zhang +108
We study the 2018 outburst of Aql X-1 via the monitor of all sky X-ray image (MAXI) data. We show that the outburst starting in February 2018 is a member of short-low class in the…
Timing analysis of 2S 1417-624 observed with NICER and Insight-HXMT
L. Ji, V. Doroshenko, A. Santangelo +112
We present a study of timing properties of the accreting pulsar 2S 1417-624 observed during its 2018 outburst, based on Swift/BAT, Fermi/GBM, Insight-HXMT and NICER observations. W…
Insight-HXMT observations of Swift J0243.6+6124 during its 2017-2018 outburst
Yue Zhang, Mingyu Ge, Liming Song +107
The recently discovered neutron star transient Swift J0243.6+6124 has been monitored by {\it the Hard X-ray Modulation Telescope} ({\it Insight-\rm HXMT). Based on the obtained dat…
X-Ray spectral evolution of PSR~J2032+4127 during the 2017 periastron passage
Partha Sarathi Pal, P. H. Thomas Tam, Yudong Cui +3
We report X-ray data analysis results obtained from Chandra, XMM-Newton, NuSTAR and Swift observations of PSR J2032+4127 taken before, during, and after the periastron on 2017 Nove…
Physics and astrophysics of strong magnetic field systems with eXTP
Andrea Santangelo, Silvia Zane, Hua Feng +38
In this paper we present the science potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission for studies of strongly magnetized objects. We will focus on the physics…
On the morphology of outbursts of accreting millisecond X-ray pulsar Aquila X-1
Can Güngör, Kazım Yavuz Ekşi, Ersin Göğüş
We present the X-ray light curves of the last two outbursts --2014 & 2016-- of the well known accreting millisecond X-ray pulsar (AMXP) Aquila X-1 using the monitor of all sky X-ra…
The ultra luminous X-ray source NuSTAR J095551+6940.8: A magnetar in a high mass X-ray binary
K. Y. Ekşi, İ. C. Andaç, S. Çıkıntoğlu +3
The recent detection of pulsations from the ultra luminous X-ray source (ULX) NuSTAR J095551+6940.8 in M82 by Bachetti et al. indicates that the object is an accreting neutron star…
Classification and Spectral Evolution of Outbursts of Aql X-1
Can Güngör, Tolga Güver, K. Yavuz Ekşi
We present a broad classification of all outbursts detected with the All-Sky Monitor (ASM) on the Rossi X-Ray Timing Explorer (RXTE) and the Monitor of All Sky X-Ray Image (MAXI) o…
Neutron stars in a perturbative gravity model with strong magnetic fields
Myung-Ki Cheoun, Cemsinan Deliduman, Can Güngör +4
We investigate the effect of a strong magnetic field on the structure of neutron stars in a model with perturbative gravity. The effect of an interior strong magnetic field…
