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…
Interferometric Evidence for Quantum Heated Particles in the Inner Region of Protoplanetary Disks around Herbig Stars
L. Klarmann, M. Benisty, M. Min +6
To understand the chemical composition of planets, it is important to know the chemical composition of the region where they form in protoplanetary disks. Due to its fundamental ro…
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…
The temporal evolution of exposed water ice-rich areas on the surface of 67P/Churyumov-Gerasimenko: spectral analysis
A. Raponi, M. Ciarniello, F. Capaccioni +16
Water ice-rich patches have been detected on the surface of comet 67P/Churyumov-Gerasimenko by the VIRTIS hyperspectral imager on-board the Rosetta spacecraft, since the orbital in…
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…
Global simulations of protoplanetary disks with net magnetic flux: I. Non-ideal MHD case
William Béthune, Geoffroy Lesur, Jonathan Ferreira
The planet-forming region of protoplanetary disks is cold, dense, and therefore weakly ionized. For this reason, magnetohydrodynamic (MHD) turbulence is thought to be mostly absent…
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…
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…
A super-Earth orbiting the nearby M-dwarf GJ 536
A. Suárez Mascareño, J. I. González Hernández, R. Rebolo +13
We report the discovery of a super-Earth orbiting the star GJ 536 based on the analysis of the radial-velocity time series from the HARPS and HARPS-N spectrographs. GJ 536 b is a p…
ALMA observations of the Corvi debris disc: inward scattering of CO-rich exocomets by a chain of 3-30 M planets?
S. Marino, M. C. Wyatt, O. Panic +10
While most of the known debris discs present cold dust at tens of AU, a few young systems exhibit hot dust analogous to the Zodiacal dust. Corvi is particularly interesting as…
Shadows and spirals in the protoplanetary disk HD 100453
M. Benisty, T. Stolker, A. Pohl +46
Understanding the diversity of planets requires to study the morphology and the physical conditions in the protoplanetary disks in which they form. We observed and spatially resolv…
On the radial velocity detection of additional planets in transiting, slowly rotating M-dwarf systems: the case of GJ 1132
Ryan Cloutier, René Doyon, Kristen Menou +3
M-dwarfs are known to commonly host high-multiplicity planetary systems. Therefore M-dwarf planetary systems with a known transiting planet are expected to contain additional small…
Absolute densities, masses, and radii of the WASP-47 system determined dynamically
J. M. Almenara, R. F. Díaz, X. Bonfils +1
We present a self-consistent modelling of the available light curve and radial velocity data of WASP-47 that takes into account the gravitational interactions between all known bod…
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…
Spectroscopic characterisation of microlensing events Towards a new interpretation of OGLE-2011-BLG-0417
A. Santerne, J. -P. Beaulieu, B. Rojas Ayala +14
The microlensing event OGLE-2011-BLG-0417 is an exceptionally bright lens binary that was predicted to present radial velocity variation at the level of several km/s. Pioneer radia…
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…
