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…
Two decades of optical variability of Small Magellanic Cloud high-mass X-ray binaries
Helena Treiber, Georgios Vasilopoulos, Charles Bailyn +2
We present an analysis of the long-term optical/IR behavior of 111 high-mass X-ray binaries (HMXBs) in the Small Magellanic Cloud based on data from the OGLE collaboration. Most sy…
Broadband study of the Be X-ray binary RX J0520.5-6932 during its outburst in 2024
H. N. Yang, C. Maitra, G. Vasilopoulos +18
A new giant outburst of the Be X-ray binary RX J0520.5-6932 was detected and subsequently observed with several space-borne and ground-based instruments. This study presents a comp…
eRASSUJ060839.5-704014: A double degenerate ultra-compact binary in the direction of the LMC
C. Maitra, F. Haberl, G. Vasilopoulos +7
Context. During four all-sky surveys (eRASS1--4), eROSITA, the soft X-ray instrument aboard Spektrum-Roentgen-Gamma (SRG) detected a new supersoft X-ray source, eRASSU J060839.5-70…
Detection of a cyclotron line in SXP 15.3 during its 2017 outburst
Chandreyee Maitra, Biswajit Paul, Frank Haberl +1
We report the results of AstroSat and NuSTAR observations of the Be/X-ray binary pulsar SXP 15.3 in the Small Magellanic Cloud during its outburst in late 2017, when the source rea…
Discovery of SXP265, a Be/X-ray binary pulsar in the Wing of the Small Magellanic Cloud
R. Sturm, F. Haberl, G. Vasilopoulos +5
We identify a new candidate for a Be/X-ray binary in the XMM-Newton slew survey and archival Swift observations that is located in the transition region of the Wing of the Small Ma…
