Discovery of the variable optical counterpart of the redback pulsar PSR J2055+1545
Marco Turchetta, Bidisha Sen, Jordan A. Simpson +5
We present the discovery of the variable optical counterpart to PSR J2055+1545, a redback millisecond pulsar, and the first radial velocity curve of its companion star. The multi-b…
A multi-wavelength study of GRS 1716-249 in outburst : constraints on its system parameters
Payaswini Saikia, David M. Russell, M. C. Baglio +27
We present a detailed study of the evolution of the Galactic black hole transient GRS 1716-249 during its 2016-2017 outburst at optical (Las Cumbres Observatory), mid-infrared (Ver…
Furiously Fast and Red: Sub-second Optical Flaring in V404 Cyg during the 2015 Outburst Peak
P. Gandhi, S. P. Littlefair, L. K. Hardy +25
We present observations of rapid (sub-second) optical flux variability in V404 Cyg during its 2015 June outburst. Simultaneous three-band observations with the ULTRACAM fast imager…
The Optical Counterpart of the Accreting Millisecond Pulsar SAX J1808.4-3658 in Outburst: Constraints on the Binary Inclination
Zhongxiang Wang, Deepto Chakrabarty, Paul Roche +6
We present multiband optical/infrared photometry of V4580 Sgr, the optical counterpart of the accretion-powered millisecond pulsar SAX J1808.4-3658, taken during the 1998 X-ray out…
The rotation speed of the companion star in Aquila X-1
T. Shahbaz, J. Casares, P. A. Charles
We have obtained medium resolution spectra of the neutron star X-ray transient Aql X-1 during quiescence. We determine the spectral type of the companion star to be K1 and also est…
