Predictions of planet detections with near infrared radial velocities in the up-coming SPIRou Legacy Survey-Planet Search
Ryan Cloutier, Étienne Artigau, Xavier Delfosse +8
The SPIRou near infrared spectro-polarimeter is destined to begin science operations at the Canada-France-Hawaii Telescope in mid-2018. One of the instrument's primary science goal…
Thermal fracturing on comets. Applications to 67P/Churyumov-Gerasimenko
N. Attree, O. Groussin, L. Jorda +12
We simulate the stresses induced by temperature changes in a putative hard layer near the surface of comet 67P/Churyumov--Gerasimenko with a thermo-viscoelastic model. Such a layer…
Dust concentration and emission in protoplanetary disks vortices

We study the dust concentration and emission in protoplanetary disks vortices. We extend the Lyra-Lin solution for the dust concentration of a single grain size to a power-law dist…
Evidence of sub-surface energy storage in comet 67P from the outburst of 2016 July 3
J. Agarwal, V. Della Corte, P. D. Feldman +67
On 3 July 2016, several instruments on board ESA's Rosetta spacecraft detected signs of an outburst event on comet 67P, at a heliocentric distance of 3.32 AU from the sun, outbound…
The circumstellar disk HD169142: gas, dust and planets acting in concert?
A. Pohl, M. Benisty, P. Pinilla +33
HD169142 is an excellent target to investigate signs of planet-disk interaction due to the previous evidence of gap structures. We performed J-band (~1.2μm) polarized intensity…
The discovery of WASP-151b, WASP-153b, WASP-156b: Insights on giant planet migration and the upper boundary of the Neptunian desert
Olivier. D. S. Demangeon, F. Faedi, G. Hébrard +31
To investigate the origin of the features discovered in the exoplanet population, the knowledge of exoplanets' mass and radius with a good precision is essential. In this paper, we…
Dynamical models to explain observations with SPHERE in planetary systems with double debris belts
C. Lazzoni, S. Desidera, F. Marzari +66
A large number of systems harboring a debris disk show evidence for a double belt architecture. One hypothesis for explaining the gap between the belts is the presence of one or mo…
The HIP 79977 debris disk in polarized light
N. Engler, H. M. Schmid, Ch. Thalmann +40
We present observations of the known edge-on debris disk around HIP 79977 (HD 146897, F star in Upper Sco, 123 pc), taken with the ZIMPOL differential polarimeter of the SPHERE ins…
Detection of a repeated transit signature in the light curve of the enigma star KIC 8462852: a 928-day period?
Flavien Kiefer, Alain Lecavelier des Etangs, Alfred Vidal-Madjar +3
As revealed by its peculiar Kepler light curve, the enigmatic star KIC 8462852 undergoes short and deep flux dimmings at a priori unrelated epochs. It presents nonetheless all othe…
Precise masses for the transiting planetary system HD 106315 with HARPS
S. C. C. Barros, H. Gosselin, J. Lillo-Box +45
The multi-planetary system HD 106315 was recently found in K2 data . The planets have periods of and days, and radii of a…
Seeds of Life in Space (SOLIS) III. Formamide in protostellar shocks: evidence for gas-phase formation
C. Codella, C. Ceccarelli, P. Caselli +47
Context: Modern versions of the Miller-Urey experiment claim that formamide (NHCHO) could be the starting point for the formation of metabolic and genetic macromolecules. Intri…
Scientific rationale for Uranus and Neptune in situ explorations
O. Mousis, D. H. Atkinson, T. Cavalié +53
The ice giants Uranus and Neptune are the least understood class of planets in our solar system but the most frequently observed type of exoplanets. Presumed to have a small rocky…
Constraints on cometary surface evolution derived from a statistical analysis of 67P's topography
J. -B. Vincent, S. F. Hviid, S. Mottola +51
We present a statistical analysis of the distribution of large scale topographic features on comet 67P/Churyumov-Gerasimenko. We observe that the cumulative cliff height distributi…
Seasonal Mass Transfer on the Nucleus of Comet 67P/Chuyumov-Gerasimenko
H. U. Keller, S. Mottola, S. F. Hviid +47
We collect observational evidence that supports the scheme of mass transfer on the nucleus of comet 67P/Churyumov-Gerasimenko. The obliquity of the rotation axis of 67P causes stro…
