A characterization of the diffuse Galactic emissions in the anti-center of the Galaxy
L. Fauvet, J. F. Macias-Perez, S. R. Hildebrandt +1
Using the Archeops and WMAP data we perform a study of the anti-center Galactic diffuse emissions - thermal dust, synchrotron, free-free and anomalous emission - at degree scales.…

We present design results of the 2nd generation VLTI instrument GRAVITY beam stabilization and light injection subsystems. Designed to deliver micro-arcsecond astrometry, GRAVITY r…
The outflow history of two Herbig-Haro jets in RCW 36: HH 1042 and HH 1043
L. E. Ellerbroek, L. Podio, L. Kaper +4
Jets around low- and intermediate-mass young stellar objects (YSOs) contain a fossil record of the recent accretion and outflow activity of their parent star-forming systems. We ai…
Colliding wind binaries and gamma-ray binaries : relativistic version of the RAMSES code
Astrid Lamberts, Guillaume Dubus, Sebastien Fromang +1
Gamma-ray binaries are colliding wind binaries (CWB) composed of a massive star a non-accreting pulsar with a highly relativistic wind. Particle acceleration at the shocks results…
Centauri A in the far infrared
R. Liseau, B. Montesinos, G. Olofsson +15
Chromospheres and coronae are common phenomena on solar-type stars. Understanding the energy transfer to these heated atmospheric layers requires direct access to the relevant empi…
Measurement of the extragalactic background light imprint on the spectra of the brightest blazars observed with H.E.S.S
H. E. S. S. Collaboration, :, A. Abramowski +195
The extragalactic background light (EBL) is the diffuse radiation with the second highest energy density in the Universe after the cosmic microwave background. The aim of this stud…
Metallicity of M dwarfs III. Planet-metallicity and planet-stellar mass correlations of the HARPS GTO M dwarf sample
V. Neves, X. Bonfils, N. C. Santos +4
Aims. The aim of this work is the study of the planet-metallicity and the planet-stellar mass correlations for M dwarfs from the HARPS GTO M dwarf subsample Methods. We use a new m…
Water ice deuteration: a tracer of the chemical history of protostars
Vianney Taquet, Phillip Peters, Claudine Kahane +5
Context. Millimetric observations have measured high degrees of molecular deuteration in several species seen around low-mass protostars. The Herschel Space Telescope, launched in…
Spiral Arms in the Asymmetrically Illuminated Disk of MWC 758 and Constraints on Giant Planets
C. A. Grady, T. Muto, J. Hashimoto +71
We present the first near-IR scattered light detection of the transitional disk associated with the Herbig Ae star MWC 758 using data obtained as part of the Strategic Exploration…
On the function describing the stellar initial mass function
Thomas Maschberger
We propose a functional form for the IMF, the L_3 IMF, which is a natural heavy-tailed approximation to the log-normal distribution. It is composed of a low-mass power law and a hi…
SiO collimated outflows driven by high-mass YSOs in G24.78+0.08
C. Codella, M. T. Beltran, R. Cesaroni +4
We imaged the molecular outflows towards the cluster of high-mass young stellar objects G24.78+0.08 at high-angular resolution using SiO emission, which is considered the classical…
An interferometric study of the Fomalhaut inner debris disk II. Keck Nuller mid-infrared observations
B. Mennesson, O. Absil, J. Lebreton +7
We report on high contrast mid-infrared observations of Fomalhaut obtained with the Keck Interferometer Nuller (KIN) showing a small resolved excess over the level expected from th…
Herschel CHESS discovery of the fossil cloud that gave birth to the Trapezium and Orion KL
Ana López-Sepulcre, Mihkel Kama, Cecilia Ceccarelli +4
As part of the Herschel Guaranteed Time Key Programme CHESS, we present the discovery of a diffuse gas component in the foreground of the intermediate-mass protostar OMC-2 FIR 4, l…
A DEBRIS Disk Around The Planet Hosting M-star GJ581 Spatially Resolved with Herschel
J. -F. Lestrade, B. C. Matthews, B. Sibthorpe +17
Debris disks have been found primarily around intermediate and solar mass stars (spectral types A-K) but rarely around low mass M-type stars. We have spatially resolved a debris di…
MHD simulations of accretion onto a dipolar magnetosphere. II. Magnetospheric ejections and stellar spin-down
Claudio Zanni, Jonathan Ferreira
This paper examines the outflows associated with the interaction of a stellar magnetosphere with an accretion disk. In particular, we investigate the magnetospheric ejections (MEs)…
SOPHIE+: First results of an octagonal-section fiber for high-precision radial velocity measurements
F. Bouchy, R. F. Diaz, G. Hébrard +5
High-precision spectrographs play a key role in exoplanet searches and Doppler asteroseismology using the radial velocity technique. The 1 m/s level of precision requires very high…
