Descripción
We present the results of the analysis of the first black hole confirmed
with GTC in the X-ray binary system XTE J1859+226. By combining optical
photometry taken with the INT, WHT and NOT with long-slit spectroscopy
with OSIRIS+GTC, we have obtained an orbital period of 6.58 h, a
secondary star radial velocity amplitude of K_2=541±70 km s^-1
and an upper limit to the inclination of 70°, implying a black hole
mass of at least 5.4 M⊙.
