Toward 3D orbits of wide sdO/B binaries I. Six composite systems spatially resolved with VLTI/GRAVITY
K. Deshmukh, S. Geier, H. Sana +7
The authors use VLTI/GRAVITY long‑baseline interferometry to spatially resolve six wide hot subdwarf (sdO/B) + main‑sequence binary systems, providing precise separations that will…

The massive hot subdwarf binary LAMOST J065816.72+094343.1
F. Mattig, B. N. Barlow, D. Liu +9
Massive short-period binaries involving hot subdwarf stars (sdO/Bs) are rare but important to constraining pathways for binary star evolution. Moreover, some of the most promising…

Experiments in binary evolution
Stephan Geier, Thomas Kupfer, Pierre Maxted +1
The majority of stars more massive than the Sun is found in binary or multiple star systems and many of them will interact during their evolution. Specific interactions, where prog…
