New Observations of the Strongly Magnetic O-star NGC 1624-2 Reveal Its Magnetic South Pole
S. Seadrow, V. Petit, D. Bohlender +6
NCG 1624-2 has the strongest detected magnetic field of all known main-sequence O-type stars. It was originally found that its magnetospheric emission lines followed a 5 mont…
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…
New Frontiers in the Study of Magnetic Massive Stars with the Habitable Worlds Observatory
Alexandre David-Uraz, Véronique Petit, Coralie Neiner +10
High-mass stars are notable for several reasons: they are characterized by strong winds, which inject momentum and enriched material into their surroundings, and die spectacularly…
SpecpolFlow: a new software package for spectropolarimetry using Python
Colin P. Folsom, Christiana Erba, Veronique Petit +8
Spectropolarimetry, the observation of polarization and intensity as a function of wavelength, is a powerful tool in stellar astrophysics. It is particularly useful for characteriz…
Stellar Magnetism
Veronique Petit, Mary E. Oksala
Stellar Magnetism affects all spectral types and exists and varies throughout the evolution of stars. Magnetic fields can affect not only the interior of stars, but also their circ…
