New Insights from Revisiting the Rotation Period of the Strongly Magnetic O Star, NGC 1624-2
S. Seadrow, V. Petit, G. A. Wade +5
NGC 1624-2 hosts the strongest surface magnetic field found on an O star thus far. When applied across several epochs of observations, the star's currently accepted rotation period…
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…
A search for chemical stratification and magnetic fields in eight field blue horizontal-branch stars
Issouf Kafando, Gregg Wade, Alexandre David-Uraz +2
In this article, we present the results of an analysis of chemical abundances and a search for magnetic fields in eight field blue horizontal-branch (BHB) stars: BD\,+010…
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…
First Observation of the Complete Rotation Period of the Ultra-Slowly Rotating Magnetic O Star HD 54879
C. Erba, C. P. Folsom, A. David-Uraz +6
HD 54879 is the most recently discovered magnetic O-type star. Previous studies ruled out a rotation period shorter than 7 years, implying that HD 54879 is the second most slowly-r…
