Multi-mission Investigation of X-ray Superorbital Modulation in the Supergiant High Mass X-ray Binary 4U 1538-52
H. I. Cohen, N. Islam, R. H. D. Corbet +7
Superorbital modulations has been detected in the supergiant High-Mass X-ray binary 4U 1538-52 using long-term monitoring with the Neil Gehrels Swift Observatory Burst Alert Telesc…
Probing multi-band variability and mode switching in the candidate transitional millisecond pulsar 3FGL J1544.6-1125
Giulia Illiano, Francesco Coti Zelati, Arianna Miraval Zanon +20
We present the most extensive high-time resolution multi-band campaign to date on the candidate transitional millisecond pulsar (tMSP) 3FGL J1544.6-1125 in the sub-luminous disk st…
Swift/XRT monitoring of the orbital and superorbital modulations in 4U 1909+07
P. Romano, H. I. Cohen, E. Bozzo +5
We report on an observational campaign performed with Swift/XRT on the wind-fed supergiant X-ray binary 4U 1909+07 to investigate the nature of the orbital and superorbital modulat…
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…
