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…
The Changing-look Optical Wind of the Flaring X-ray Transient Swift J1858.6-0814
T. Muñoz-Darias, M. Armas Padilla, F. Jiménez-Ibarra +15
We present the discovery of an optical accretion disk wind in the X-ray transient Swift J1858.6-0814. Our 90-spectrum data set, taken with the 10.4m GTC telescope over 8 different…
