PKS 2005-489 at VHE: Four Years of Monitoring with HESS and Simultaneous Multi-wavelength Observations
The HESS Collaboration, F. Acero
VHE observations of PKS 2005-489 were made with HESS from 2004 through 2007, together with three simultaneous multi-wavelength campaigns performed with XMM-Newton and RXTE in 2004…
The origin of the prompt GRB spectrum
F. Daigne, Z. Bosnjak, G. Dubus
Using a detailed model of the internal shock phase, we discuss the origin of the prompt emission in gamma-ray bursts. We focus on the identification of the dominant radiative proce…
A super-Earth transiting a nearby low-mass star
David Charbonneau, Zachory K. Berta, Jonathan Irwin +16
A decade ago, the detection of the first transiting extrasolar planet provided a direct constraint on its composition and opened the door to spectroscopic investigations of extraso…
The HARPS search for southern extra-solar planets. XX. Planets around the active star BD-08:2823
G. Hebrard, S. Udry, G. Lo Curto +13
We report the detection of a planetary system around BD-08:2823, that includes at least one Uranus-mass planet and one Saturn-mass planet. This discovery serendipitously originates…
Strong near-infrared emission in the sub-AU disk of the Herbig Ae star HD163296: evidence for refractory dust?
M. Benisty, A. Natta, A. Isella +12
We present new long-baseline spectro-interferometric observations of the HerbigAe star HD163296 obtained in the H and K bands with the AMBER instrument at VLTI. The observations co…
The Canada-France High-z Quasar Survey: nine new quasars and the luminosity function at redshift 6
Chris J. Willott, Philippe Delorme, Celine Reyle +9
We present discovery imaging and spectroscopy for nine new z ~ 6 quasars found in the Canada-France High-z Quasar Survey (CFHQS) bringing the total number of CFHQS quasars to 19. B…
Localising the VHE gamma-ray source at the Galactic Centre
The HESS Collaboration, F. Acero
The inner 10 pc of our galaxy contains many counterpart candidates of the very high energy (VHE; > 100 GeV) gamma-ray point source HESS J1745-290. Within the point spread function…
Revealing the sub-AU asymmetries of the inner dust rim in the disk around the Herbig Ae star R CrA
S. Kraus, K. -H. Hofmann, F. Malbet +5
Models predict that in the innermost AU of the disk around Herbig Ae/Be star, the dust disk forms a "puffed-up" inner rim, which should result in a strongly asymmetric brightness d…
Panchromatic observations and modeling of the HV Tau C edge-on disk
G. Duchene, C. McCabe, C. Pinte +12
We present new high spatial resolution (<~ 0.1") 1-5 micron adaptive optics images, interferometric 1.3 mm continuum and 12CO 2-1 maps, and 350 micron, 2.8 and 3.3 mm fluxes measur…
The Taurus Spitzer Survey: New Candidate Taurus Members Selected Using Sensitive Mid-Infrared Photometry
L. M. Rebull, D. L. Padgett, C. -E. McCabe +31
We report on the properties of pre-main-sequence objects in the Taurus molecular clouds as observed in 7 mid- and far-infrared bands with the Spitzer Space Telescope. There are 215…
An estimate of the chemical composition of Titan's lakes
D. Cordier, O. Mousis, J. -I. Lunine +2
Hundreds of radar-dark patches interpreted as lakes have been discovered in the north and south polar regions of Titan. We have estimated the composition of these lakes by using th…
The Case of AB Aurigae's Disk in Polarized Light: Is There Truly a Gap?
Marshall D. Perrin, Glenn Schneider, Gaspard Duchene +4
Using the NICMOS coronagraph, we have obtained high-contrast 2.0 micron imaging polarimetry and 1.1 micron imaging of the circumstellar disk around AB Aurigae on angular scales of…
Complex magnetic topology and strong differential rotation on the low-mass T Tauri star V2247 Oph
J. -F. Donati, M. B. Skelly, J. Bouvier +7
From observations collected with the ESPaDOnS spectropolarimeter at the Canada-France-Hawaii Telescope, we report the detection of Zeeman signatures on the low-mass classical TTaur…
On the power spectrum of solar surface flows
M. Rieutord, T. Roudier, F. Rincon +4
The aim of this work is to give new observational constraints on solar surface flows by determining the horizontal scale dependence of the velocity and intensity fields, as represe…
High resolution X-ray spectroscopy of the Seyfert 1 Mrk841: insights into the warm absorber and warm emitter
A. L. Longinotti, E. Costantini, P. O. Petrucci +6
The Seyfert 1 galaxy Mrk841 was observed five times between 2001 and 2005 by the XMM-Newton X-ray observatory. The source is well known for showing spectral complexity in the varia…

Detection and Characterization of Planets in Binary and Multiple Systems
A. Eggenberger
Moderately close binaries are a special class of targets for planet searches. From a theoretical standpoint, their hospitality to giant planets is uncertain and debated. From an ob…

Intermittency of interstellar turbulence: extreme velocity-shears and CO emission on milliparsec scale
E. Falgarone, J. Pety, P. Hily-Blant
The condensation of diffuse gas into molecular clouds occurs at a rate driven largely by turbulent dissipation. This process still has to be caught in action and characterized. A m…
