Superorbital variability in the quiescent black hole X-ray transient A0620-00
Enzo A. Saavedra, Roi Alonso, Teo Muñoz-Darias +10
Quiescent black hole low-mass X-ray binaries provide a key setting for probing accretion physics at low luminosities. A0620-00, the archetypal system in this class, has remained in…

Revisiting the fundamental parameters for the black hole X-ray transient Swift J1753.5-0127
I. V. Yanes-Rizo, M. A. P. Torres, J. Casares +4
We present time-resolved Gran Telescopio Canarias optical spectroscopy and William Herschel Telescope -band photometry of the X-ray transient SWIFT J1753.5-0127 in quiescence. T…
