Calibrating angular momentum transport in intermediate-mass stars from gravity-mode asteroseismology. II. Modelling 2937 BAF-type stars
J. S. G. Mombarg, S. Mathis
Asteroseismology of gravity (g)-mode pulsators covering BAF-type stars have shown that angular momentum is redistributed during the main sequence. The efficiency of the transport,…
Gravity-mode main-sequence pulsators in the open clusters NGC 3532 and NGC 2516: Instability strip, near-core rotation, and internal structure
Gang Li, Chenyu He, Joey S. G. Mombarg +2
Context. Studying pulsating stars in clusters opens a new window onto stellar physics. Gravity-mode (g-mode) pulsators in open clusters allow us to measure their near-core rotation…
Populations of tidal and pulsating variables in eclipsing binaries
Alex Kemp, Jasmine Vrancken, Joey S. G. Mombarg +4
In this work, we seek to characterise a large sample of 14377 main sequence eclipsing binaries in terms of their stellar, asteroseismic, and orbital properties. We conduct manual v…
Is a 1D perturbative method sufficient for asteroseismic modelling of Cephei pulsators? Implications for measurements of rotation and internal magnetic fields
J. S. G. Mombarg, V. Vanlaer, S. B. Das +6
Asymmetries in the observed rotational splittings of a multiplet contain information about the star's rotation profile and internal magnetic field. However, to exploit this informa…
The inertial dip as a window on the convective core dynamics
Lucas Barrault, Lisa Bugnet, Stéphane Mathis +1
Gamma Dor stars are ideal targets for studies of the innermost dynamical properties of stars, due to their rich frequency spectrum of gravito-inertial modes propagating in the radi…
HR6819: a puffed-up stripped star system challenging stable mass transfer theory
A. Picco, P. Marchant, H. Sana +8
HR6819 is the first system with a puffed-up low mass stripped star and a classical Be star whose nature has been confirmed by optical interferometry. It shows the most extreme mass…
