Searching for orbital period modulation in X-ray observations of the symbiotic X-ray binary GX 1+4
Moritz Klawin, Lorenzo Ducci, M. Mirac Serim +3
The symbiotic X-ray binary GX 1+4 possesses a number of peculiar properties that have been studied since the early 1970s. In particular, the orbital period has been a point of deba…
The high-energy cyclotron line in 2S 1417-624 discovered with Insight-HXMT during the 2018 outburst
Q. Liu, A. Santangelo, L. D. Kong +7
We report a detailed timing and spectral analysis of the X-ray pulsar 2S~1417-624 using the data from Insight-HXMT during the 2018 outburst. The pulse profiles are highly variable…
Temporal and spectral variations of the X-ray pulsar Cen X-3 observed by NuSTAR
Qi Liu, Wei Wang, Andrea Santangelo +3
We report a time-resolved analysis of the accreting X-ray pulsar Cen X-3 using observations carried out by NuSTAR, which cover approximately two binary orbits in different intensit…
XMM-Newton observations of the peculiar Be X-ray binary A0538-66
Michela Rigoselli, Caterina Tresoldi, Lorenzo Ducci +1
A0538-66 is a neutron star/Be X-ray binary located in the Large Magellanic Cloud and, since its discovery in the seventies, it showed a peculiar behavior which makes it a unique ob…
Soft X-ray emission from the classical nova AT 2018bej
A. Tavleev, L. Ducci, V. F. Suleimanov +4
Classical novae are known to demonstrate a supersoft X-ray source (SSS) state following outbursts, which is associated with residual thermonuclear burning on the white dwarf (WD) s…
Discovery of the first anti-glitch event in the rotation-powered pulsar PSR B0540-69
Youli Tuo, M. M. Serim, Marco Antonelli +5
Using data from the Neutron star Interior Composition ExploreR (NICER) observatory, we identified a permanent spin frequency decrease of $Δν=-(1.04\pm0.07)\times 10^{-7}\,\mathrm{H…
