Description
We present 5 yr of optical and infrared data of the black hole candidate
MAXI J1659-152 covering its 2010 outburst, decay, and quiescence.
Combining optical data taken during the outburst decay, we obtain an
orbital period of 2.414 ± 0.005 h, in perfect agreement with the
value previously measured from X-ray dips. In addition, we detect a
clear H α excess in MAXI J1659-152 with data taken during the
outburst decay. We also detect a single hump modulation most likely
produced by irradiation. Assuming that the maximum occurs at orbital
phase 0.5, we constrain the phase of the X-ray dips to be ˜0.65.
We also detect the quiescent optical counterpart at r΄ =
24.20 ± 0.08, I = 23.32 ± 0.02, and H = 20.7 ± 0.1.
These magnitudes provide colour indices implying an M2-M5 donor star
assuming 60 per cent contribution from a disc component in the
r΄ band.

Accreting black-holes and neutron stars in X-ray binaries provide an ideal laboratory for exploring the physics of compact objects, yielding not only confirmation of the existence of stellar mass black holes via dynamical mass measurements, but also the best opportunity for probing high-gravity environments and the physics of accretion; the most
