Investigating the Magnetospheres of Rapidly Rotating B-type Stars

C. L. Fletcher, V. Petit, Y. Naze +6

Recent spectropolarimetric surveys of bright, hot stars have found that ~10% of OB-type stars contain strong (mostly dipolar) surface magnetic fields (~kG). The prominent paradigm…

Magnetic B stars observed with BRITE: Spots, magnetospheres, binarity, and pulsations

G. A. Wade, D. H. Cohen, C. Fletcher +16

Magnetic B-type stars exhibit photometric variability due to diverse causes, and consequently on a variety of timescales. In this paper we describe interpretation of BRITE photomet…

X-ray, UV and optical analysis of supergiants: Ori

Raul E. Puebla, D. John Hillier, Janos Zsargó +2

We present a multi-wavelength (X-ray to optical) analysis, based on non-local thermodynamic equilibrium photospheric+wind models, of the B0 Ia-supergiant: ~Ori. The aim is to te…

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…

Discovery of a magnetic field in the rapidly-rotating O-type secondary of the colliding-wind binary HD 47129 (Plaskett's star)

J. H. Grunhut, G. A. Wade, M. Leutenegger +14

We report the detection of a strong, organized magnetic field in the secondary component of the massive O8III/I+O7.5V/III double-lined spectroscopic binary system HD 47129 (Plasket…

Solving the Puzzle of the Massive Star System Theta 2 Orionis A

V. Petit, M. Gagne, D. H. Cohen +5

The young O9.5 V spectroscopic binary Theta 2 Ori A shows moderately hard X-ray emission and relatively narrow X-ray lines, suggesting that it may be a Magnetically Confined Wind S…

The MiMeS Project: Overview and Current Status

G. A. Wade, E. Alecian, D. A. Bohlender +18

The Magnetism in Massive Stars (MiMeS) Project is a consensus collaboration among many of the foremost international researchers of the physics of hot, massive stars, with the basi…

A Multi-Phase Suzaku Study of X-rays from tau Sco

R. Ignace, L. M. Oskinova, M. Jardine +5

We obtained relatively high signal-to-noise X-ray spectral data of the early massive star tau Sco (B0.2V) with the Suzaku XIS instrument. This source displays several unusual featu…

Discovery of Rotational Braking in the Magnetic Helium-Strong Star Sigma Orionis E

R. H. D. Townsend, M. E. Oksala, D. H. Cohen +2

We present new U-band photometry of the magnetic Helium-strong star Sigma Ori E, obtained over 2004-2009 using the SMARTS 0.9-m telescope at Cerro Tololo Inter-American Observatory…
