First scattered-light images of the gas-rich debris disk around 49 Ceti
É. Choquet, J. Milli, Z. Wahhaj +31
We present the first scattered-light images of the debris disk around 49 ceti, a ~40 Myr A1 main sequence star at 59 pc, famous for hosting two massive dust belts as well as large…
Chromium isotope evidence in ejecta deposits for the nature of Paleoproterozoic impactors
Berengere Mougel, Frederic Moynier, Christa Gopel +1
Non-mass dependent chromium isotopic signatures have been successfully used to determine the presence and identification of extra-terrestrial materials in terrestrial impact rocks.…
3D Radiation Non-ideal Magnetohydrodynamical Simulations Of The Inner Rim In Protoplanetary Disks
M. Flock, S. Fromang, N. J. Turner +1
Many planets orbit within an AU of their stars, raising questions about their origins. Particularly puzzling are the planets found near the silicate sublimation front. We investiga…
Discovery of a low-mass companion inside the debris ring surrounding the F5V star HD206893
Julien Milli, Pascale Hibon, Valentin Christiaens +30
Uncovering the ingredients and the architecture of planetary systems is a very active field of research that has fuelled many new theories on giant planet formation, migration, com…
Upper limits for Mass and Radius of objects around Proxima Cen from SPHERE/VLT
D. Mesa, A. Zurlo, J. Milli +36
The recent discovery of an earth-like planet around Proxima Centauri has drawn much attention to this star and its environment. We performed a series of observations of Proxima Cen…
Observing transiting planets with JWST -- Prime targets and their synthetic spectral observations
Paul Mollière, Roy van Boekel, Jeroen Bouwman +3
The James Webb Space Telescope will enable astronomers to obtain exoplanet spectra of unprecedented precision. Especially the MIRI instrument may shed light on the nature of the cl…
The SHARDDS survey: first resolved image of the HD114082 debris disk in Lower Centaurus Crux with SPHERE
Zahed Wahhaj, Julien Milli, Grant Kennedy +17
We present the first resolved image of the debris disk around the 16+/-8 Myr old star, HD 114082. The observation was made in the H-band using the SPHERE instrument. The star is at…
Decimetre-scaled spectrophotometric properties of the nucleus of comet 67P/Churyumov-Gerasimenko from OSIRIS observations
C. Feller, S. Fornasier, P. H. Hasselmann +43
We present the results of the photometric and spectrophotometric properties of the 67P/Churyumov-Gerasimenko nucleus derived with the OSIRIS instrument during the closest fly-by ov…
Three radial gaps in the disk of TW Hydrae imaged with SPHERE
Roy van Boekel, Thomas Henning, Jonathan Menu +24
We present scattered light images of the TW Hya disk performed with SPHERE in PDI mode at 0.63, 0.79, 1.24 and 1.62 micron. We also present H2/H3-band ADI observations. Three disti…
Assessing magnetic torques and energy fluxes in close-in star-planet systems
A Strugarek
Planets in close-in orbit interact with the magnetized wind of their hosting star. This magnetic interaction was proposed to be a source for enhanced emissions in the chromosphere…
Elemental partitioning and isotopic fractionation of Zn between metal and silicate and geochemical estimation of the S content of the Earth's core
B. Mahan, J. Siebert, E. A. Pringle +1
Zinc metal-silicate fractionation provides experimental access to the conditions of core formation and Zn has been used to estimate the S contents of the Earth's core and of the bu…
Multiple rings in the transition disk and companion candidates around RXJ1615.3-3255. High contrast imaging with VLT/SPHERE
J. de Boer, G. Salter, M. Benisty +36
We search for signs of ongoing planet-disk interaction and study the distribution of small grains at the surface of the transition disk around RXJ1615.3-3255 (RX J1615). We observe…
Exploring Biases of Atmospheric Retrievals in Simulated JWST Transmission Spectra of Hot Jupiters
M. Rocchetto, I. P. Waldmann, O. Venot +2
With a scheduled launch in October 2018, the James Webb Space Telescope (JWST) is expected to revolutionise the field of atmospheric characterization of exoplanets. The broad wavel…
An investigation of the low-DeltaV near-Earth asteroids (341843) 2008 EV5 and (52381) 1993 HA. Two suitable targets for the ARM and MarcoPolo-M5 space missions
D. Perna, M. Popescu, F. Monteiro +3
The Asteroid Redirect Mission (ARM) under development by NASA is being planned to collect a multi-meter boulder from a near-Earth asteroid (NEA), and to bring it to the cis-lunar s…
Summer fireworks on comet 67P
J. -B. Vincent, M. F. A'Hearn, Z. -Y. Lin +52
During its two years mission around comet 67P/Churyumov-Gerasimenko, ESA's Rosetta spacecraft had the unique opportunity to follow closely a comet in the most active part of its or…
Evolution of CO, CH, and OCS abundances relative to HO in the coma of comet 67P around perihelion from Rosetta/VIRTIS-H observations
D. Bockelée-Morvan, J. Crovisier, S. Erard +19
Infrared observations of the coma of 67P/Churyumov-Gerasimenko were carried out from July to September 2015, i.e., around perihelion (13 August 2015), with the high-resolution chan…
Belt(s) of debris resolved around the Sco-Cen star HIP 67497
M. Bonnefoy, J. Milli, F. Ménard +15
In 2015, we initiated a survey of Scorpius-Centaurus A-F stars that are predicted to host warm-inner and cold-outer belts of debris similar to the case of the system HR~8799. The s…
Inferring the interplanetary dust properties from remote observations and simulations
Jeremie Lasue, Anny-Chantal Levasseur-Regourd, Nicolas Fray +1
Since in situ studies and interplanetary dust collections only provide a spatially limited amount of information about the interplanetary dust properties, it is of major importance…
