Detection of warm water vapour in Taurus protoplanetary discs by Herschel
P. Riviere-Marichalar, F. Ménard, W. F. Thi +12
Line spectra of 68 Taurus T Tauri stars were obtained with the Herschel-PACS (Photodetector Array Camera & Spectrometer) instrument as part of the GASPS (Gas Evolution in Protoplan…
Detection of HF emission from the Orion Bar
F. F. S. van der Tak, V. Ossenkopf, Z. Nagy +3
The clumpy density structure of photon-dominated regions is well established, but the physical properties of the clumps and of the surrounding interclump medium are only approximat…
An icy Kuiper-Belt around the young solar-type star HD 181327
J. Lebreton, J. -C. Augereau, W. -F. Thi +18
HD 181327 is a young F5/F6V star belonging to the Beta Pictoris moving group (12 Myr). It harbors an optically thin belt of circumstellar material at 90 AU. We aim to study the dus…
Molecule survival in magnetized protostellar disk winds. I. Chemical model and first results
D. Panoglou, S. Cabrit, G. Pineau des Forets +3
Molecular counterparts to atomic jets have been detected within 1000 AU of young stars. Reproducing them is a challenge for proposed ejection models. We explore whether molecules m…
High resolution imaging of young M-type stars of the solar neighborhood: Probing the existence of companions down to the mass of Jupiter
P. Delorme, A. M. Lagrange, G. Chauvin +5
Context. High contrast imaging is a powerful technique to search for gas giant planets and brown dwarfs orbiting at separation larger than several AU. Around solar-type stars, gian…
Three-dimensional mid-infrared photonic circuits in chalcogenide glass
Airan Rodenas, Guillermo Martin, Brahim Arezki +7
We report the fabrication of single mode buried channel waveguides for the whole mid-infrared transparency range of chalcogenide sulphide glasses by means of direct laser writing.…
First spectro-interferometric survey of Be stars I. Observations and constraints on the disks geometry and kinematics
Anthony Meilland, Florentin Millour, Samer Kanaan +5
Context. Classical Be stars are hot non-supergiant stars surrounded by a gaseous circumstellar disk that is responsible for the observed infrared-excess and emission lines. The phe…
Stellar jitter from variable gravitational redshift: implications for RV confirmation of habitable exoplanets
H. M. Cegla, C. A. Watson, T. R. Marsh +6
A variation of gravitational redshift, arising from stellar radius fluctuations, will introduce astrophysical noise into radial velocity measurements by shifting the centroid of th…
An incisive look at the symbiotic star SS Leporis -- Milli-arcsecond imaging with PIONIER/VLTI
N. Blind, H. M. J. Boffin, J. -P. Berger +4
Context. Determining the mass transfer in a close binary system is of prime importance for understanding its evolution. SS Leporis, a symbiotic star showing the Algol paradox and p…
A Surprising Dynamical Mass for V773~Tau~B
A. Boden, G. Torres, G. Duchene +4
We report on new high-resolution imaging and spectroscopy on the multiple T Tauri star system V773 Tau over the 2003 -- 2009 period. With these data we derive relative astrometry,…
Transmission spectrum of Venus as a transiting exoplanet
David Ehrenreich, Alfred Vidal-Madjar, Thomas Widemann +6
On 5-6 June 2012, Venus will be transiting the Sun for the last time before 2117. This event is an unique opportunity to assess the feasibility of the atmospheric characterisation…
Multilayer modeling of porous grain surface chemistry I. The GRAINOBLE model
Vianney Taquet, Cecilia Ceccarelli, Claudine Kahane
Mantles of iced water, mixed with CO, H2CO, and CH3OH are formed during the so called prestellar core phase. In addition, radicals are also thought to be formed on the grain surfac…
Particle acceleration at relativistic shock waves
Martin Lemoine, Guy Pelletier
Relativistic sources, e.g. gamma-ray bursts, pulsar wind nebulae and powerful active galactic nuclei produce relativistic outflows that lead to the formation of collisionless shock…
Tracing colliding winds in the UV line orbital variability of gamma-ray binaries
A. Szostek, G. Dubus, M. V. McSwain
Gamma-ray binaries emit most of their radiated power beyond ~10 MeV. The non-thermal emission is thought to arise from the interaction of the relativistic wind of a rotation-powere…
Band-Limited Coronagraphs using a halftone-dot process: II. Advances and laboratory results for arbitrary telescope apertures
P. Martinez, C. Dorrer, M. Kasper
The band-limited coronagraph is a nearly ideal concept that theoretically enables perfect cancellation of all the light of an on-axis source. Over the past years, several prototype…
Spatially resolving the outer atmosphere of the M giant BK Vir in the CO first overtone lines with VLTI/AMBER
K. Ohnaka, K. -H. Hofmann, D. Schertl +5
The mass-loss mechanism in normal K--M giant stars with small variability amplitudes is not yet understood, although they are the majority among red giant stars. We present high-sp…
The HARPS search for southern extra-solar planets XXXI. The M-dwarf sample
X. Bonfils, X. Delfosse, S. Udry +11
(Abridged) Searching for planets around stars with different masses probes the outcome of planetary formation for different initial conditions. This drives observations of a sample…
Metallicity of M dwarfs II. A comparative study of photometric metallicity scales
V. Neves, X. Bonfils, N. C. Santos +6
Stellar parameters are not easily derived from M dwarf spectra, which are dominated by complex bands of diatomic and triatomic molecules and not well described at the line by line…
