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…
Evidence for a black hole in the historical X-ray transient A 1524-61 (=KY TrA)
I. V. Yanes-Rizo, M. A. P. Torres, J. Casares +5
We present VLT spectroscopy, high-resolution imaging and time-resolved photometry of KY TrA, the optical counterpart to the X-ray binary A 1524-61. We perform a refined astrometry…
The orbital period, black hole mass and distance to the X-ray transient GRS 1716-249 (=N Oph 93)
J. Casares, I. V. Yanes-Rizo, M. A. P. Torres +7
We present evidence for a 0.278(8) d (=6.7 h) orbital period in the X-ray transient GRS 1716-249 (=N Oph 93), based on a superhump modulation detected during the 1995 mini-outburst…
Delimiting the black hole mass in the X-ray transient MAXI J1659-152 with H spectroscopy
M. A. P. Torres, P. G. Jonker, J. Casares +2
MAXI J1659-152 is a 2.4 h orbital period X-ray dipping transient black hole candidate. We present spectroscopy of its quiescent counterpart where we detect H emissi…
The Formation of a 70 Msun Black Hole at High Metallicity
K. Belczynski, R. Hirschi, E. A. Kaiser +7
A 70Msun BH was discovered in Milky Way disk in a long period and almost circular detached binary system (LB-1) with a high metallicity 8Msun B star companion. Current consensus on…
