Constraining the overcontact phase in massive binary evolution -- III. Period stability of known B+B and O+B overcontact systems

Jasmine Vrancken, Michael Abdul-Masih, Ana Escorza +3

Binary systems play a crucial role in massive star evolution. Systems composed of B-type and O-type stars are of particular interest due to their potential to lead to very energeti…

Low-mass stellar and substellar candidate companions around massive stars in Sco OB1 and M17

Tinne Pauwels, Maddalena Reggiani, Hugues Sana +1

Massive stars are recognized for their high degree of multiplicity, yet the mass ratio regime below 0.1 remains insufficiently explored. It is therefore unknown whether extremely l…

The VLT-FLAMES Tarantula Survey: Observational evidence for two distinct populations of massive runaway stars in 30 Doradus

H. Sana, O. H. Ramírez-Agudelo, V. Hénault-Brunet +17

Two main scenarios have been proposed for origin of massive runaway stars -- dynamical ejection or release from a binary at the first core collapse -- but their relative contributi…

The Nature of Unseen Companions in Massive Single-Line Spectroscopic Binaries

Hugues Sana, Michael Abdul-Masih, Gareth Banyard +14

Massive stars are predominantly found in binaries and higher order multiples. While the period and eccentricity distributions of OB stars are now well established across different…

HR 6819 is a binary system with no black hole -- revisiting the source with infrared interferometry and optical integral field spectroscopy

A. J. Frost, J. Bodensteiner, Th. Rivinius +16

Two scenarios have been proposed to match the existing observational constraints of the object HR 6819. The system could consist of a close inner B-type giant plus a black hole (BH…

The Gaia-ESO Survey: The analysis of the hot-star spectra

R. Blomme, S. Daflon, M. Gebran +44

The Gaia-ESO Survey (GES) is a large public spectroscopic survey that has collected, over a period of 6 years, spectra of ~ 10^5 stars. This survey provides not only the reduced sp…
