The formation of Cataclysmic Variables: the influence of nova eruptions
G. Nelemans, L. Siess, S. Repetto +2
The theoretical and observed populations of pre-cataclysmic variables (pre-CVs) are dominated by systems with low-mass white dwarfs (WDs), while the WD masses in CVs are typically…
Compact Binary Merger Rates: Comparison with LIGO/Virgo Upper Limits
Krzysztof Belczynski, Serena Repetto, Daniel E. Holz +5
We compare evolutionary predictions of double compact object merger rate densities with initial and forthcoming LIGO/Virgo upper limits. We find that: (i) Due to the cosmological r…
Discovery of a red supergiant counterpart to RX~J004722.4-252051, a ULX in NGC 253
M. Heida, M. A. P. Torres, P. G. Jonker +6
We present two epochs of near-infrared spectroscopy of the candidate red supergiant counterpart to RX~J004722.4-252051, a ULX in NGC 253. We measure radial velocities of the object…
Constraining the formation of black-holes in short-period Black-Hole Low-Mass X-ray Binaries
Serena Repetto, Gijs Nelemans
The formation of stellar mass black holes is still very uncertain. Two main uncertainties are the amount of mass ejected in the supernova event (if any) and the magnitude of the na…
VLT spectroscopy of the Black Hole Candidate Swift J1357.2-0933 in Quiescence
M. A. P. Torres, P. G. Jonker, J. C. A. Miller-Jones +3
We present time-resolved optical spectroscopy of the counterpart to the high-inclination black hole low-mass X-ray binary Swift J1357.2-0933 in quiescence. Absorption features from…
