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…
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…
PIMMS: Pulsation-Informed Magnetic Mapping of Stars with Zeeman-Doppler Imaging I. Formalism and numerical tests
C. Gutteridge, C. Neiner, C. Catala +1
Context. Magneto-asteroseismology is a novel technique allowing for more precise determinations of internal properties of magnetic pulsating stars, but requires an accurate charact…
Detecting and characterising the magnetic field of exoplanets
A. Strugarek, S. V. Berdyugina, V. Bourrier +25
Magnetic fields play a crucial role in planetary evolution and habitability. While the intrinsic magnetic fields of solar system planets are relatively well understood, the magneti…
Discovery of the binary nature of the magnetospheric B-type star Oph A
M. E. Shultz, I. Berry, D. Bohlender +11
The nearby B-type star Oph A was recently identified as a rapidly rotating magnetic B-type star with variable radio and X-ray emission consistent with a magnetospheric origin.…
