Results from the first spectropolarimetric survey of Dor pulsators
J. Labadie-Bartz, R. Ouazzani, C. Neiner +8
Context. Magnetic fields can have an important influence on stellar structure and evolution. In intermediate-mass (A- and F-type) stars, there are many known stars with directly me…
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…
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…
Discovery of new magnetic δ Scuti stars and impact of magnetism on pulsation excitation
K. Thomson-Paressant, C. Neiner, J. Labadie-Bartz +3
Context. At this time, the list of known magnetic δ Scuti stars is extremely limited, with only a handful of well-studied examples. Aims. We seek to expand this list, by retrievin…
