Rapid Orbital Decay in the Ultracompact Double-degenerate Binary eRASSU J060839.5704014
Rahul Sharma, Chandreyee Maitra, Frank Haberl +9
We present timing and spectral analysis of the recently identified ultracompact double-degenerate (DD) white dwarf binary eRASSU J060839.5704014 using observations from NICER an…
A comprehensive catalogue of high-mass X-ray binaries in the Large Magellanic Cloud detected during the first eROSITA all-sky survey
D. Kaltenbrunner, C. Maitra, F. Haberl +9
The Magellanic Clouds, the closest star-forming galaxies to the Milky Way, offer an excellent environment to study high-mass X-ray binaries. While the Small Magellanic Cloud has be…
Broadband study of the Be/X-ray binary pulsar eRASSU J012422.9-724248 in the Magellanic Bridge, near the Eastern Wing of the Small Magellanic Cloud
Haonan Yang, Chandreyee Maitra, Frank Haberl +4
The first four all-sky surveys with eROSITA the soft X-ray instrument on board the Spektrum-Roentgen-Gamma (SRG) satellite revealed a new X-ray source, eRASSU J012422.9-724248, in…
Don't torque like that. Measuring compact object magnetic fields with analytic torque models
J. J. R. Stierhof, E. Sokolova-Lapa, K. Berger +10
Context. Changes of the rotational period observed in various magnetized accreting sources are generally attributed to the interaction between the in-falling plasma and the large-s…
Optical flares due to X-ray irradiation during BeXRB major outbursts
G. Vasilopoulos
Be X-ray binaries (BeXRBs) may show strong X-ray and optical variability, and can exhibit some of the brightest outbursts that break through the Eddington limit. Major X-ray outbur…
Detection of the optical counterpart of the transient ULX NGC300 ULX-1: a nascent black hole - neutron star binary?
André-Nicolas Chené, Georgios Vasilopoulos, Lidia M. Oskinova +1
The end points of massive star evolution are poorly known, especially those in interacting binary systems containing compact objects, such as neutron stars or black holes. Such sys…
