Mass ratio determination from Halpha lines in Black-Hole X-ray transients
Jorge Casares
We find that the mass ratio q in quiescent black hole (BH) X-ray transients is tightly correlated with the ratio of the double peak separation (DP) to the full-width-half maximum (…
A FWHM-K2 correlation in Black-Hole transients
Jorge Casares
We compare Halpha emission profiles of 12 dynamically confirmed black holes (BHs) and 2 neutron star X-ray transients (SXTs) in quiescence with those of a sample of 43 Cataclysmic…
HS 2325+8205 - an ideal laboratory for accretion disk physics
S. Pyrzas, B. T. Gaensicke, J. R. Thorstensen +12
We identify HS 2325+8205 as an eclipsing, frequently outbursting dwarf nova with an orbital period of 279.841731(5) min. Spectroscopic observations are used to derive the radial ve…
On the binary nature of the gamma-ray sources AGL J2241+4454 (=MWC 656) and HESS J0632+057 (=MWC 148)
J. Casares, M. Ribo, I. Ribas +3
We present optical spectroscopy of MWC 656 and MWC 148, the proposed optical counterparts of the gamma-ray sources AGL J2241+4454 and HESS J0632+0 57, respectively. The main parame…
Evidence for a black-hole in the X-ray transient XTE J1859+226
J. M. Corral-Santana, J. Casares, T. Shahbaz +3
We present the results of time-resolved optical photometry and spectroscopy of the X-ray transient XTE J1859+226 (V406 Vul). Photometric observations taken during 2000 and 2008 rev…
