Physical properties of the eclipsing binary KIC 9851944 and analysis of its tidally-perturbed p- and g-mode pulsations
Zachary Jennings, John Southworth, Kresimir Pavlovski +1
Stars that are both pulsating and eclipsing offer an important opportunity to better understand many of the physical phenomena that occur in stars, because it is possible to measur…
Asteroseismology of the young open cluster NGC 2516 I: Photometric and spectroscopic observations
Gang Li, Conny Aerts, Timothy R. Bedding +8
Asteroseismic modelling of isolated star presents significant challenges due to the difficulty in accurately determining stellar parameters, particularly the stellar age. These cha…
Age-dating the young open cluster UBC 1 with g-mode asteroseismology, gyrochronology, and isochrone fitting
D. J. Fritzewski, T. Van Reeth, C. Aerts +3
UBC 1 is an open cluster discovered in Gaia data and located near the edge of the Transiting Exoplanet Survey Satellite's (TESS) continuous viewing zone. We aim to provide age cons…
Probing the physics in the core boundary layers of the double-lined B-type binary KIC4930889 from its gravito-inertial modes
Mathias Michielsen, Timothy Van Reeth, Andrew Tkachenko +1
Stellar evolution models of B-type stars are still uncertain in terms of internal mixing properties, notably in the area between the convective core and the radiative envelope. Thi…
A massive helium star with a sufficiently strong magnetic field to form a magnetar
T. Shenar, G. A. Wade, P. Marchant +13
Magnetars are highly magnetized neutron stars; their formation mechanism is unknown. Hot helium-rich stars with spectra dominated by emission lines are known as Wolf-Rayet stars. W…
Unresolved Rossby and gravity modes in 214 A and F stars showing rotational modulation
Andreea I. Henriksen, Victoria Antoci, Hideyuki Saio +9
Here we report an ensemble study of 214 A- and F-type stars observed by \textit{Kepler}, exhibiting the so-called \textit{hump and spike} periodic signal, explained by Rossby modes…
The ESO UVES/FEROS Large Programs of TESS OB pulsators. I. Global stellar parameters from high-resolution spectroscopy
Nadya Serebriakova, Andrew Tkachenko, Sarah Gebruers +7
Modern stellar structure and evolution theory experiences a lack of observational calibrations for the interior physics of intermediate- and high-mass stars. This leads to discrepa…
Tidally perturbed g-mode pulsations in a sample of close eclipsing binaries
T. Van Reeth, C. Johnston, J. Southworth +4
Context. Thanks to the high-precision photometry from space missions such as Kepler and TESS, tidal perturbations and tilting of pulsations have been detected in more than a dozen…
High-mass eclipsing binaries: a testbed for models of interior structure and evolution -- Accurate fundamental properties and surface chemical composition for V1034 Sco, GL Car, V573 Car and V346 Cen
K. Pavlovski, J. Southworth, A. Tkachenko +2
The surface chemical compositions of stars are affected by physical processes which bring the products of thermonuclear burning to the surface. Despite their potential in understan…
