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…
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…
Expanding stellar horizons with polarized light
J. Vandersnickt, R. Ochoa Armenta, V. Vanlaer +16
The polarization of light is a critically under-utilized, rich source of information in astronomy. For stars in particular, surface magnetism polarization that can be detected and…
Asteroseismic detection of an internal magnetic field in the B0.5V pulsator HD 192575
Jelle Vandersnickt, Vincent Vanlaer, Mathijs Vanrespaille +1
Internal magnetic fields are an elusive component of stellar structure. However, they can play an important role in stellar structure and evolution models through efficient angular…
Asteroseismology of HD 23734, HD 68703, and HD 73345 using K2-TESS Space-based Photometry and High-resolution Spectroscopy
Santosh Joshi, Athul Dileep, Eugene Semenko +14
In this paper, we present a comprehensive study of three stars, HD 23734, HD 68703, and HD 73345, which were previously observed as chemically peculiar candidates within the Nainit…
Learning novel representations of variable sources from multi-modal data via autoencoders
P. Huijse, J. De Ridder, L. Eyer +18
Gaia Data Release 3 (DR3) published for the first time epoch photometry, BP/RP (XP) low-resolution mean spectra, and supervised classification results for millions of variable sour…
