The MiMeS Project: First Results

J. H. Grunhut, E. Alecian, D. A. Bohlender +11

Massive stars are those stars with initial masses above about 8 times that of the sun, eventually leading to catastrophic explosions in the form of supernovae. These represent the…

Discovery of fossil magnetic fields in the intermediate-mass pre-main sequence stars

E. Alecian, G. A. Wade, C. Catala

It is now well-known that the surface magnetic fields observed in cool, lower-mass stars on the main sequence (MS) are generated by dynamos operating in their convective envelopes.…

Is the wind of the Oe star HD 155806 magnetically confined?

V. Petit, A. W. Fullerton, S. Bagnulo +1

Oe stars are a subset of the O-type stars that exhibit emission lines from a circumstellar disk. The recent detection of magnetic fields in some O-type stars suggests a possible ex…

Magnetic fields, winds and X-rays of massive stars: A spectropolarimetric survey of the Orion cluster

V. Petit, G. A. Wade, L. Drissen +2

In massive stars, magnetic fields are thought to confine the outflowing radiatively-driven wind, resulting in X-ray emission that is harder, more variable and more efficient than t…

Magnetic topologies of the Herbig Ae/Be stars

E. Alecian, G. A. Wade, C. Catala +9

Our recent discoveries of magnetic fields in a small number of Herbig Ae/Be (HAeBe) stars, the evolutionary progenitors of main sequence A/B stars, raise new questions about the or…

Magnetic fields and chemical peculiarities of the very young intermediate-mass binary system HD 72106

C. P. Folsom, G. A. Wade, O. Kochukhov +9

The recently discovered magnetic Herbig Ae and Be stars may provide qualitatively new information about the formation and evolution of magnetic Ap and Bp stars. We have performed a…

The pecular magnetic field morphology of the white dwarf WD 1953-011: evidence for a large-scale magnetic flux tube?

G. Valyavin, G. A. Wade, S. Bagnulo +4

We present and interpret new spectropolarimetric observations of the magnetic white dwarf WD 1953-011. Circular polarization and intensity spectra of the H spectral line demonst…

The effect of rotation on the abundances of the chemical elements of the A-type stars in the Praesepe cluster

L. Fossati, S. Bagnulo, J. Landstreet +5

We study how chemical abundances of late B-, A- and early F-type stars evolve with time, and we search for correlations between the abundance of chemical elements and other stellar…

Discovery of two magnetic massive stars in the Orion Nebula Cluster: a clue to the origin of neutron star magnetic fields?

V. Petit, G. A. Wade, L. Drissen +2

The origin of the magnetic fields in neutron stars, and the physical differences between magnetars and strongly magnetised radio pulsars are still under vigorous debate. It has bee…
