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…
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…
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…
New observations of NGC 1624-2 reveal a complex magnetospheric structure and underlying surface magnetic geometry
A. David-Uraz, V. Petit, M. E. Shultz +5
NGC 1624-2 is the most strongly magnetized O-type star known. Previous spectroscopic observations of this object in the ultraviolet provided evidence that it hosts a large and dens…
