We analyze phase-resolved spectra of two compact mass-transferring hot subdwarf binaries and constrain their accretion disk luminosities.

We model the future evolution of the 70-min hot subdwarf-white dwarf binary CD-3011223 using MESA, predicting initiation of mass transfer in a few Myr and thermonuclear explosion of the white dwarf around 55 Myr from now.

We present a VLTI/GRAVITY interferometric survey of Southern Galactic Wolf-Rayet stars in search of elusive wide companions predicted by evolutionary models. Despite probing a large and uncharted period range, we find the wide binaries to be largely missing. We also discuss serendipetous by-products of our GRAVITY survey, beyond our search for companions.

We confirm the wide binary status of the highly magnetic quasi Wolf-Rayet star HD 45166. With a single snapshot observation with VLTI/GRAVITY, the two binary components are spatially resolved, allowing for preliminary dynamical mass measurements and motivating follow-up observations to determine the full 3D orbit.

We present a massive O+BH binary candidate in the Tarantula nebula identified using VLT/FLAMES spectroscopic observations. We also discuss the challenges we face when searching for black hole companions to massive stars in the Tarantula nebula and the way forward to find more O+BH binaries.
