The VLT-FLAMES survey of massive stars: constraints on stellar evolution from the chemical compositions of rapidly rotating Galactic and Magellanic Cloud B-type stars
I. Hunter, I. Brott, N. Langer +8
We have previously analysed the spectra of 135 early B-type stars in the LMC and found several groups of stars that have chemical compositions that conflict with the theory of rota…
A Three-Decade Outburst of the LMC Luminous Blue Variable R127 Draws to a Close
Nolan R. Walborn, Otmar Stahl, Roberto C. Gamen +7
The paradigmatic Luminous Blue Variable R127 in the Large Magellanic Cloud has been found in the intermediate, peculiar early-B state, and substantially fainter in visual light, si…
The weak magnetic field of the O9.7 supergiant zeta Orionis A
J. -C. Bouret, J. -F. Donati, F. Martins +4
We report here the detection of a weak magnetic field of 50 - 100 G on the O9.7 supergiant zeta Ori A, using spectropolarimetric observations obtained with NARVAL at the 2m Telesco…
Towards an understanding of the Of?p star HD191612: Phase-resolved multiwavelength observations
Yael Naze, Gregor Rauw, A. M. T. Pollock +2
We present the analysis of phase-resolved X-ray and optical observations of the peculiar hot star HD191612 (Of?p). This star is known to display line-profile variations that are re…
The surprising magnetic topology of tauSco: fossil remnant or dynamo output?
JF Donati, ID Howarth, MM Jardine +9
We report the discovery of a medium-strength (~0.5kG) magnetic field on the young, massive star tauSco (B0.2V), which becomes the third-hottest magnetic star known. Circularly pola…
Bright OB stars in the Galaxy - III. Constraints on the radial stratification of the clumping factor in hot star winds from a combined Halpha, IR and radio analysis
J. Puls, N. Markova, S. Scuderi +4
Recent results strongly challenge the canonical picture of massive star winds: various evidence indicates that currently accepted mass-loss rates, Mdot, may need to be revised down…
