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…
XMM-Newton Perspective of the Unique Magnetic Binary- Lupi
Ayan Biswas, Gregg A. Wade, Poonam Chandra +3
The Lupi A (HD 136504) system stands out among magnetic massive binaries as the only short-period binary system in which both components have detectable magnetic fields. The pr…
Using ZDI maps to determine magnetic forces and torques at the photospheres of Early-type stars
James MacDonald, Tali Natan, Véronique Petit +2
We use the magnetic field components measured by Zeeman Doppler imaging (ZDI) to calculate the stellar surface force and torque due to magnetic stresses for the fast rotators O…
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…
MOBSTER -- III. HD 62658: a magnetic Bp star in an eclipsing binary with a non-magnetic 'identical twin'
M. E. Shultz, C. Johnston, J. Labadie-Bartz +9
HD 62658 (B9p V) is a little-studied chemically peculiar star. Light curves obtained by the Kilodegree Extremely Little Telescope (KELT) and Transiting Exoplanet Survey Satellite (…
X-ray emission from the giant magnetosphere of the magnetic O-type star NGC 1624-2
V. Petit, D. H. Cohen, G. A. Wade +7
We observed NGC 1624-2, the O-type star with the largest known magnetic field Bp~20 kG), in X-rays with the ACIS-S camera onboard the Chandra X-ray Observatory. Our two observation…
Rotation, spectral variability, magnetic geometry and magnetosphere of the Of?p star CPD -28 2561
G. A. Wade, R. H. Barbá, J. Grunhut +14
We report magnetic and spectroscopic observations and modeling of the Of?p star CPD -28 2561. Using more than 75 new spectra, we have measured the equivalent width variations and e…
Investigating the origin of cyclical wind variability in hot, massive stars - I. On the dipolar magnetic field hypothesis
A. David-Uraz, G. A. Wade, V. Petit +9
OB stars exhibit various types of spectral variability associated with wind structures, including the apparently ubiquitous discrete absorption components (DACs). These are propose…
Tau Sco: discovery of the clones
V. Petit, D. L. Massa, W. L. F. Marcolino +3
The B0.2 V magnetic star tau Sco stands out from the larger population of massive magnetic OB stars due to its high X-ray activity and remarkable wind, apparently related to its pe…
tau Sco: The discovery of the clones
V. Petit, D. L. Massa, W. L. F. Marcolino +3
The B0.2 V magnetic star tau Sco stands out from the larger population of massive magnetic OB stars due to its remarkable, superionized wind, apparently related to its peculiar mag…
Discovery of a magnetic field in the O9 sub-giant star HD 57682 by the MiMeS Collaboration
J. H. Grunhut, G. A. Wade, W. L. F. Marcolino +11
We report the detection of a strong, organised magnetic field in the O9IV star HD 57682, using spectropolarimetric observations obtained with ESPaDOnS at the 3.6-m Canada-France-Ha…
