Exotic optical variability in the black hole X-ray binary IGR J17091-3624
Payaswini Saikia, David M. Russell, D. M. Bramich +9
IGR J17091-3624 is a distinctive black hole X-ray binary exhibiting exotic variability, including complex "heartbeat" oscillations in its X-ray light curves, similar to those obser…
A Multi-wavelength Characterization of the 2023 Outburst of MAXI J1807+132: Manifestations of Disk Instability and Jet Emission
Sandeep K. Rout, M. Cristina Baglio, Andrew Hughes +19
Several phenomenological aspects of low-luminosity neutron star transients, such as atolls, remain poorly understood. One such source, MAXI J1807+132, entered its latest outburst i…
Lack of emission lines in the optical spectra of SAX J1808.4-3658 during reflaring of the 2019 outburst
L. Asquini, M. C. Baglio, S. Campana +5
We present spectroscopy of the accreting X-ray binary and millisecond pulsar SAX J1808.4-3658. These observations are the first to be obtained during a reflaring phase. We collecte…
Clockwise evolution in the hardness-intensity diagram of the black hole X-ray binary Swift J1910.2-0546
Payaswini Saikia, David M. Russell, Saarah F. Pirbhoy +5
We present a detailed study of optical data from the 2012 outburst of the candidate black hole X-ray binary Swift J1910.2-0546 using the Faulkes Telescope and Las Cumbres Observato…
A misfired outburst in the neutron star X-ray binary Centaurus X-4
M. C. Baglio, P. Saikia, D. M. Russell +12
We report on a long-term optical monitoring of the neutron star X-ray binary Centaurus X-4 performed during the last 13.5 years. This source has been in quiescence since its outbur…
Optical and ultraviolet pulsed emission from an accreting millisecond pulsar
F. Ambrosino, A. Miraval Zanon, A. Papitto +28
Millisecond spinning, low magnetic field neutron stars are believed to attain their fast rotation in a 0.1-1 Gyr-long phase during which they accrete matter endowed with angular mo…
