A refined dynamical mass for the black hole in the X-ray transient XTE J1859+226
I. V. Yanes Rizo, M. A. P. Torres, J. Casares +8
We present two contiguous nights of simultaneous time-resolved GTC spectroscopy and WHT photometry of the black hole X-ray transient XTE J1859+226, obtained in 2017 July during qui…
A persistent ultraviolet outflow from an accreting neutron star binary transient
N. Castro Segura, C. Knigge, K. S. Long +31
All disc-accreting astrophysical objects produce powerful outflows. In binaries containing neutron stars (NS) or black holes, accretion often takes place during violent outbursts.…
Optical nebular emission following the most luminous outburst of Aquila X-1
G. Panizo-Espinar, T. Muñoz-Darias, M. Armas Padilla +3
Aquila X-1 is a prototypical neutron star low mass X-ray binary and one of the most studied X-ray transients. We present optical spectroscopy obtained with the Gran Telescopio Cana…
Optical spectroscopy of 4U 1812-12: an ultra-compact X-ray binary seen through an H II region
M. Armas Padilla, T. Muñoz-Darias, F. Jiménez-Ibarra +6
The persistent, low-luminosity neutron star X-ray binary 4U 1812-12 is a potential member of the scarce family of ultra-compact systems. We performed deep photometric and spectrosc…
Discovery of optical outflows and inflows in the black hole candidate GRS 1716-249
V. A. Cúneo, T. Muñoz-Darias, J. Sánchez-Sierras +12
We present optical spectroscopy obtained with the GTC, VLT and SALT telescopes during the decline of the 2016-2017 outburst of the black hole candidate GRS 1716-249 (Nova Oph 1993)…
The binary mass ratio in the black hole transient MAXI J1820+070
M. A. P. Torres, J. Casares, F. Jiménez-Ibarra +5
We present intermediate resolution spectroscopy of the optical counterpart to the black hole X-ray transient MAXI J1820+070 (=ASASSN-18ey) obtained with the OSIRIS spectrograph on…
