Binary evolution at the extremes of mass-transfer efficiency: Contact, mergers, and population signatures
Jan Henneco, Utkarsh R. Basu, Fabian R. N. Schneider
Binary star evolution remains inherently uncertain, and several physical processes are not well understood. These open questions in binary physics come in addition to major uncerta…
The symphony of pulsations and binarity among massive stars using HERMES spectroscopy and TESS photometry
K. Thomson-Paressant, D. M. Bowman, F. Nardini +16
A wide range of variability mechanisms exist among intermediate mass and massive stars, which are not yet fully understood. Using complementary data sources for a large population…
Binarity at LOw Metallicity (BLOeM): massive star variability revealed using a novel software tool for point-spread function fitting of TESS images
Pieterjan J. Van Daele, Dominic M. Bowman, Roey Ovadia +12
Massive stars, the progenitors of neutron stars and black holes, play a crucial role in shaping the chemical and radiative properties of entire galaxies through their winds and exp…
The effect of near-core mixing on rejuvenation and the asteroseismic properties of massive accretors
Jan Henneco, Dominic M. Bowman
The relatively recent revelation of the high occurrence rate of binary interactions, especially in intermediate- and high-mass systems, has prompted multiple investigations into th…
1D stellar mergers: entropy sorting and PyMMAMS
Max Heller, Fabian R. N. Schneider, Jan Henneco +2
Stellar multiple systems are the norm, not the exception, with many systems undergoing interaction phases during their lifetimes. A subset of these interactions can lead to stellar…
The physical properties of post-mass-transfer binaries
Rhys Seeburger, Hans-Walter Rix, Kareem El-Badry +4
Aims. We present and analyse the detailed physical properties of six binary stellar systems, originally proposed as possible star-black hole binaries on the basis of radial velocit…
