Flashing fast: characterising the 2025 outburst of MAXI J1957+032
A. Sanna, G. Illiano, M. C. Baglio +13
MAXI J1957+032 is an accreting millisecond X-ray pulsar that shows brief, recurrent outbursts in an ultra-compact ~1 h orbit. We characterise the 2025 outburst using X-ray timing a…
Disentangling the stellar atmosphere and the focused wind in different accretion states of Cygnus X-1
M. Brigitte, P. Hadrava, B. Kubátová +8
In high-mass X-ray binaries (HMXBs), the compact object accretes the strong stellar wind of an O-B supergiant companion star. X-ray flux variations alter the stellar wind's ionizat…
Multi-band study of the flaring mode emission in the transitional millisecond pulsar PSR J1023+0038
M. C. Baglio, F. Coti Zelati, A. K. Hughes +17
We present a comprehensive study of the flaring mode of the transitional millisecond pulsar (tMSP) PSR J1023+0038 during its X-ray sub-luminous state, using strictly simultaneous X…
Determining the nature of IC 10 X-2: A comprehensive study of the Optical/Infrared emission from an extragalactic BeHMXB
Jwaher Alnaqbi, Joseph D. Gelfand, Payaswini Saikia +7
We present a comprehensive analysis of the optical and infrared (IR) properties of high-mass X-ray binary (HMXB) IC 10 X-2, classified as a super-giant HMXB and super-fast X-ray tr…
Long term optical variations in Swift J1858.6-0814: evidence for ablation and comparisons to radio properties
L. Rhodes, D. M. Russell, P. Saikia +5
We present optical monitoring of the neutron star low-mass X-ray binary Swift J1858.6-0814 during its 2018-2020 outburst and subsequent quiescence. We find that there was strong op…
