Asteroseismic forward modelling of 36 Cep pulsators and inferences on their internal differential rotation
Mathijs Vanrespaille, Dario J. Fritzewski, Vincent Vanlaer +1
Asteroseismic observations of the interior rotation of main sequence stars have shown that angular momentum transport is much more efficient than expected. Which transport mechanis…
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…
Variability classification of TESS targets in LOPS2, the first long-term pointing field of PLATO. Version 1 of the public variability catalogue
Mykyta Kliapets, Pablo Huijse, Jeroen Audenaert +28
The PLAnetary Transits and Oscillations of stars (PLATO) mission is expected to launch in January 2027. A total of 8\% of its data rate will be dedicated to complementary science t…
Isochrone-cloud fitting and asteroseismology of the Kepler open cluster NGC6866
Haotian Wang, Gang Li, Dario J. Fritzewski +2
We investigate how isochrones computed with different input physics and initial conditions affect the age dating of the open cluster NGC 6866, and compare the results with asterose…
Large-scale time-series spectroscopy for stellar ages
David Gruner, Sydney A. Barnes, Ansgar Reiners +16
To date, Galactic Astronomy has largely concerned itself with astrophysical processes, and with the locations, space motions and compositions of objects. Consider, for example, the…
Exploiting tidal asteroseismology in binary populations from combined space photometry and time-resolved high-resolution spectroscopy
Ema Šipková, Alex Kemp, Dario Fritzewski +4
Space-based photometry has substantially increased the number of pulsating stars found in binary systems by more than four orders of magnitude. Combined with high-resolution spectr…
