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…
eRASSt J040515.6-745202, an X-ray burster in the Magellanic Bridge
F. Haberl, G. Vasilopoulos, C. Maitra +13
During the third all-sky survey (eRASS3), eROSITA, the soft X-ray instrument aboard Spectrum-Roentgen-Gamma, detected a new hard X-ray transient, eRASSt J040515.6-745202, in the di…
TESS Shines Light on the Origin of the Ambiguous Nuclear Transient ASASSN-18el
Jason T. Hinkle, Christopher S. Kochanek, Benjamin J. Shappee +11
We analyze high-cadence data from the Transiting Exoplanet Survey Satellite (TESS) of the ambiguous nuclear transient (ANT) ASASSN-18el. The optical changing-look phenomenon in ASA…
RX J0529.8-6556: a BeXRB pulsar with an evolving optical period and out of phase X-ray outbursts
H. Treiber, G. Vasilopoulos, C. D. Bailyn +12
We report the results of eROSITA and NICER observations of the June 2020 outburst of the Be/X-ray binary pulsar RX J0529.8-6556 in the Large Magellanic Cloud, along with the analys…
Chandra probes the X-ray variability of M51 ULX-7: evidence of propeller transition and X-ray dips on orbital periods
G. Vasilopoulos, F. Koliopanos, F. Haberl +4
We report on the temporal properties of the ULX pulsar M51 ULX-7 inferred from the analysis of the 2018-2020 Swift/XRT monitoring data and archival Chandra data obtained over a per…
