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…

Matter ejections behind the highs and lows of the transitional millisecond pulsar PSR J1023+0038

M. C. Baglio, F. Coti Zelati, S. Campana +23

Transitional millisecond pulsars are an emerging class of sources that link low-mass X-ray binaries to millisecond radio pulsars in binary systems. These pulsars alternate between…
