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…
The Milky Way's external disc constrained by 2MASS star counts
C. Reyle, D. J. Marshall, A. C. Robin +1
Context. Thanks to recent large scale surveys in the near infrared such as 2MASS, the galactic plane that most suffers from extinction is revealed and its overall structure can be…
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 in the Orion Nebula 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…
Multifrequency study of the ring nebula SG13
J. Vasquez, C. E. Cappa, S. Pineault
We investigate the morphology and kinematics of the interstellar medium in the environs of the open cluster Mrk50, which includes the Wolf-Rayet star WR157 and a number of early B-…
Science with ASKAP - the Australian Square Kilometre Array Pathfinder
S. Johnston, R. Taylor, M. Bailes +47
[ABRIDGED VERSION] The future of cm and m-wave astronomy lies with the Square Kilometre Array (SKA), a telescope under development by a consortium of 17 countries. The SKA will be…
