Detection of the optical counterpart of the transient ULX NGC300 ULX-1: a nascent black hole - neutron star binary?
André-Nicolas Chené, Georgios Vasilopoulos, Lidia M. Oskinova +1
The end points of massive star evolution are poorly known, especially those in interacting binary systems containing compact objects, such as neutron stars or black holes. Such sys…

The long-period spectroscopic orbit and dust creation in the Wolf-Rayet binary system WR 125
Noel D. Richardson, Andrea R. Daly, Peredur M. Williams +8
Several long-period binaries with a carbon-rich Wolf-Rayet star and an O star produce dust in their wind collisions. In eccentric binaries, this is seen most strongly near periastr…
