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…
Asteroseismic predictions for a massive main-sequence merger product
J. Henneco, F. R. N. Schneider, M. Heller +2
The products of stellar mergers between two massive main-sequence (MS) stars appear as seemingly normal MS stars after a phase of thermal relaxation, if not for certain peculiariti…
A Low Metallicity Massive Contact Binary Star System Candidate in WLM identified by Hubble and James Webb Space Telescope imaging
Maude Gull, Daniel R. Weisz, Kareem El-Badry +15
We present archival HST and JWST ultraviolet through near infrared time series photometric observations of a massive minimal-contact binary candidate in the metal-poor galaxy WLM (…
Merger seismology: distinguishing massive merger products from genuine single stars using asteroseismology
Jan Henneco, Fabian R. N. Schneider, Saskia Hekker +1
Products of stellar mergers are predicted to be common in stellar populations and can potentially explain stars with peculiar properties. When the merger occurs after the initially…
Contact tracing of binary stars: Pathways to stellar mergers
Jan Henneco, Fabian R. N. Schneider, Eva Laplace
Stellar mergers lead to diverse phenomena: rejuvenated blue stragglers, magnetised and peculiar stars, transients and nebulae. Using a grid of about 6000 detailed 1D binary evoluti…
Evolution and final fate of massive post-common-envelope binaries
Dandan Wei, Fabian R. N. Schneider, Philipp Podsiadlowski +3
Mergers of neutron stars (NSs) and black holes (BHs) are nowadays observed routinely thanks to gravitational-wave (GW) astronomy. In the isolated binary-evolution channel, a common…
The effect of the centrifugal acceleration on period spacings of gravito-inertial modes in intermediate-mass stars
Jan Henneco, Timothy Van Reeth, Vincent Prat +3
The Kepler and TESS missions delivered high-precision, long-duration photometric time series for hundreds of main-sequence stars with gravito-inertial (g) pulsation modes. This hig…
