Exo-Milankovitch Cycles I: Orbits and Rotation States
Russell Deitrick, Rory Barnes, Thomas R. Quinn +3
The obliquity of the Earth, which controls our seasons, varies by only ~2.5 degrees over ~40,000 years, and its eccentricity varies by only ~0.05 over 100,000 years. Nonetheless, t…
Rotationally-resolved spectroscopy of Jupiter Trojans (624) Hektor and (911) Agamemnon
Davide Perna, Nicolas Bott, Tetiana Hromakina +3
We present the first-ever rotationally resolved spectroscopic investigation of (624) Hektor and (911) Agamemnon, the two largest Jupiter Trojans. The visible and near-infrared spec…
Photometric observations of nine Transneptunian objects and Centaurs
T. Hromakina, D. Perna, I. Belskaya +3
We present the results of photometric observations of six Transneptunian objects and three Centaurs, estimations of their rotational periods and corresponding amplitudes. For six o…
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…
Toward the analysis of JWST exoplanet spectra: Identifying troublesome model parameters
Jean-Loup Baudino, Paul Molliere, Olivia Venot +3
Given the forthcoming launch of the James Webb Space Telescope (JWST) which will allow observ- ing exoplanet atmospheres with unprecedented signal-over-noise ratio, spectral covera…
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…
Three years of SPHERE: the latest view of the morphology and evolution of protoplanetary discs
Antonio Garufi, Myriam Benisty, Tomas Stolker +11
Spatially resolving the immediate surroundings of young stars is a key challenge for the planet formation community. SPHERE on the VLT represents an important step forward by incre…
Asteroid (21) Lutetia: Disk-resolved Photometric Analysis of Baetica Region
P. H. Hasselmann, M. A. Barucci, S. Fornasier +4
(21) Lutetia has been visited by Rosetta mission on July 2010 and observed with a phase angle ranging from 0.15 to 156.8 degrees. The Baetica region, located at the north pole has…
Characterizing spectral continuity in SDSS u'g'r'i'z' asteroid photometry
P. H. Hasselmann, M. Fulchignoni, J. M. Carvano +2
Context. The 4th release of the SDSS Moving Object Catalog (SDSSMOC) is presently the largest photometric dataset of asteroids. Up to this point, the release of large asteroid data…
Seasonal evolution of , , and abundances in Titan's lower stratosphere
M. Sylvestre, N. A. Teanby, S. Vinatier +2
We study the seasonal evolution of Titan's lower stratosphere (around 15~mbar) in order to better understand the atmospheric dynamics and chemistry in this part of the atmosphere.…
Atmospheric tides and their consequences on the rotational dynamics of terrestrial planets
Pierre Auclair-Desrotour, Jacques Laskar, Stéphane Mathis
Atmospheric tides can have a strong impact on the rotational dynamics of planets. They are of most importance for terrestrial planets located in the habitable zone of their host st…
The thermal emission of Centaurs and Trans-Neptunian objects at millimeter wavelengths from ALMA observations
E. Lellouch, R. Moreno, T. Müller +9
The sensitivity of ALMA makes it possible to detect thermal mm/submm emission from small/distant Solar System bodies at the sub-mJy level. Measured fluxes are primarily sensitive t…
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…
Investigation of the inner structures around HD169142 with VLT/SPHERE
R. Ligi, A. Vigan, R. Gratton +47
We present observations of the Herbig Ae star HD169142 with VLT/SPHERE instruments InfraRed Dual-band Imager and Spectrograph (IRDIS) ( and bands) and the Integral Fie…
Size and shape of Chariklo from multi-epoch stellar occultations
R Leiva, B Sicardy, J I B Camargo +28
We use data from five stellar occultations observed between 2013 and 2016 to constrain Chariklo's size and shape, and the ring reflectivity. We consider four possible models for Ch…
Mid-Infrared Polarization of Herbig Ae/Be Discs
Dan Li, Charles M. Telesco, Han Zhang +4
We measured mid-infrared polarization of protoplanetary discs to gain new insight into their magnetic fields. Using CanariCam at the 10.4 m Gran Telescopio Canarias, we detected li…
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…
