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…

The mass of the white dwarf in YY Dra (=DO Dra): Dynamical measurement and comparative study with X-ray estimates
Ayoze Álvarez-Hernández, Manuel A. P. Torres, Tariq Shahbaz +7
We present a dynamical study of the intermediate polar cataclysmic variable YY Dra based on time-series observations in the band, where the donor star is known to be the major…

Optical and near-infrared polarization of the black hole X-ray binary A0620-00 in quiescence
Vadim Kravtsov, Alexandra Veledina, Andrei V. Berdyugin +12
We present simultaneous high-precision optical polarimetric and near-infrared (NIR) to ultraviolet (UV) photometric observations of low-mass black hole X-ray binary A0620-00 in the…
