Interstellar chemistry of nitrogen hydrides in dark clouds
Romane Le Gal, Pierre Hily-Blant, Alexandre Faure +3
The aim of the present work is to perform a comprehensive analysis of the interstellar chemistry of nitrogen, focussing on the gas-phase formation of the smallest polyatomic specie…
The Origin and Universality of the Stellar Initial Mass Function
Stella S. R. Offner, Paul C. Clark, Patrick Hennebelle +5
We review current theories for the origin of the Stellar Initial Mass Function (IMF) with particular focus on the extent to which the IMF can be considered universal across various…
Evidence of a discontinuous disk structure around the Herbig Ae star HD 139 614
Alexis Matter, Lucas Labadie, Alexander Kreplin +6
A new class of pre-main sequence objects has been recently identified as pre-transitional disks. They present near-infrared excess coupled to a flux deficit at about 10 microns and…
An independent determination of Fomalhaut b's orbit and the dynamical effects on the outer dust belt
Hervé Beust, Jean-Charles Augereau, Amy Bonsor +7
The nearby star Fomalhaut harbours a cold, moderately eccentric dust belt with a sharp inner edge near 133 au. A low-mass, common proper motion companion (Fom b), was discovered ne…
Searching for companions down to 2 AU from beta Pictoris using the L'-band AGPM coronagraph on VLT/NACO
Olivier Absil, Julien Milli, Dimitri Mawet +6
Context. The orbit of the giant planet discovered around beta Pic is slightly inclined with respect to the outer parts of the debris disc, which creates a warp in the inner debris…
The close environment of high-mass X-ray binaries at high angular resolution I. VLTI/AMBER and VLTI/PIONIER near-infrared interferometric observations of Vela X-1
E. Choquet, P. Kervella, J. -B. Le Bouquin +7
Recent improvements on the sensitivity and spectral resolution of X-ray observations have led to a better understanding of the properties of matter in the vicinity of High Mass X-r…
CoRoT 223992193: A new, low-mass, pre-main sequence eclipsing binary with evidence of a circumbinary disk
Edward Gillen, Suzanne Aigrain, Amy McQuillan +12
We present the discovery of CoRoT 223992193, a double-lined, detached eclipsing binary, comprising two pre-main sequence M dwarfs, discovered by the CoRoT space mission during a 23…
A Bcool magnetic snapshot survey of solar-type stars
S. C. Marsden, P. Petit, S. V. Jeffers +20
Stellar magnetic field measurements obtained from spectropolarimetry offer key data for activity and dynamo studies, and we present the results of a major high-resolution spectropo…
Roadmap on the theoretical work of BinaMIcS
S. Mathis, C. Neiner, E. Alecian +2
We review the different theoretical challenges concerning magnetism in interacting binary or multiple stars that will be studied in the BinaMIcS (Binarity and Magnetic Interactions…
The BinaMIcS project: binarity and magnetism
C. Neiner, E. Alecian, the BinaMIcS collaboration
We present the BinaMIcS project, its goals and the first BinaMIcS spectropolarimetric observations obtained with Narval at TBL and ESPaDOnS at CFHT: dedicated time-series for targe…
Molecules in the transition disk orbiting T Cha
G. G. Sacco, J. H. Kastner, T. Forveille +4
We seek to establish the presence and properties of gas in the circumstellar disk orbiting T Cha, a nearby (d~110 pc), relatively evolved (age ~5-7 Myr) yet actively accreting 1.5…
Alignment in star-debris disc systems seen by Herschel
J. S. Greaves, G. M. Kennedy, N. Thureau +28
Many nearby main-sequence stars have been searched for debris using the far-infrared Herschel satellite, within the DEBRIS, DUNES and Guaranteed-Time Key Projects. We discuss here…
The magnetospheric accretion/ejection process in young stellar objects: open issues and perspectives
J. Bouvier
This summary talk aims at highlighting some of the remaining open issues regarding the physics of the magnetospheric accretion/ejection process in young stellar objects (YSOs). It…
Braking down an accreting protostar: disc-locking, disc winds, stellar winds, X-winds and Magnetospheric Ejecta
Jonathan Ferreira
Classical T Tauri stars are low mass young forming stars that are surrounded by a circumstellar accretion disc from which they gain mass. Despite this accretion and their own contr…
The magnetic characteristics of Galactic OB stars from the MiMeS survey of magnetism in massive stars
G. A. Wade, J. Grunhut, E. Alecian +11
The Magnetism in Massive Stars (MiMeS) project represents the largest systematic survey of stellar magnetism ever undertaken. Based on a sample of over 550 Galactic B and O-type st…
Testing excitation models of rapidly oscillating Ap stars with interferometry
M. S. Cunha, D. Alentiev, I. M. Brandão +1
