Debris discs in binaries: morphology and photometric signatures
Philippe Thebault, Quentin Kral, Johan Olofsson
We aim to see whether debris belts evolving in between two stars may be impacted by the presence of the companion and whether this leaves any detectable signature that could be obs…
The search for radio emission from the exoplanetary systems 55 Cancri, Andromedae, and Boötis using LOFAR beam-formed observations
Jake D. Turner, Philippe Zarka, Jean-Mathias Grießmeier +8
Observing planetary auroral radio emission is the most promising method to detect exoplanetary magnetic fields, the knowledge of which will provide valuable insights into the plane…

We predicted a stellar occultation of the bright star Gaia DR1 4332852996360346368 (UCAC4 385-75921) (m= 14.0 mag) by the centaur 2002 GZ for 2017 May 20$^{\rm th}…
A medium-resolution spectrum of the exoplanet HIP 65426 b
Simon Petrus, Mickaël Bonnefoy, Gaël Chauvin +18
Medium-resolution integral-field spectrographs (IFS) coupled with adaptive-optics such as Keck/OSIRIS, VLT/MUSE, or SINFONI are appearing as a new avenue for enhancing the detectio…
1D photochemical model of the ionosphere and the stratosphere of Neptune
M. Dobrijevic, J. C. Loison, V. Hue +2
Neptune remains a mysterious world that deserves further exploration and is a high-priority objective for a future planetary mission in order to better understand the formation and…
Euclid: Identification of asteroid streaks in simulated images using StreakDet software
M. Pöntinen, M. Granvik, A. A. Nucita +57
The ESA Euclid space telescope could observe up to 150 000 asteroids as a side product of its primary cosmological mission. Asteroids appear as trailed sources, that is streaks, in…
A Single-chord Stellar Occultation by the Extreme Trans-Neptunian Object (541132) Leleākūhonua
Marc W. Buie, Rodrigo Leiva, John M. Keller +32
A stellar occultation by the extreme large-perihelion trans-Neptunian object (541132) Leleākūhonua (also known by the provisional designation of 2015 TG387) was predicted by the Lu…
Stellar occultations enable milliarcsecond astrometry for Trans-Neptunian objects and Centaurs
F. L. Rommel, F. Braga-Ribas, J. Desmars +66
Trans-Neptunian objects (TNOs) and Centaurs are remnants of our planetary system formation, and their physical properties have invaluable information for evolutionary theories. Ste…
A single-armed spiral in the protoplanetary disk around HD34282 ?
J. de Boer, C. Ginski, G. Chauvin +17
During the evolution of protoplanetary disks into planetary systems we expect to detect signatures that trace mechanisms such as planet-disk interaction. Protoplanetary disks displ…
Solid tidal friction in multi-layer planets: Application to Earth, Venus, a Super Earth and the TRAPPIST-1 planets. Can a multi-layer planet be approximated as a homogeneous planet?
Emeline Bolmont, Sylvain N. Breton, Gabriel Tobie +3
With the discovery of TRAPPIST-1 and its seven planets within 0.06 au, the correct treatment of tidal interactions is becoming necessary. The eccentricity, rotation, and obliquity…
Potential asteroid discoveries by the ESA Gaia mission: Results from follow-up observations
B. Carry, W. Thuillot, F. Spoto +42
Since July 2014, the ESA Gaia mission has been surveying the entire sky down to magnitude 20.7 in the visible. In addition to the millions of stars, thousands of Solar System Objec…
A multi-chord stellar occultation by the large trans-Neptunian object (174567) Varda
D. Souami, F. Braga-Ribas, B. Sicardy +41
We present results from the first recorded stellar occultation by the large trans-Neptunian object (174567) Varda that was observed on September 10, 2018. Varda belongs…
Dynamical Evidence of a Spiral Arm--Driving Planet in the MWC 758 Protoplanetary Disk
Bin Ren, Ruobing Dong, Rob G. van Holstein +22
More than a dozen young stars host spiral arms in their surrounding protoplanetary disks. The excitation mechanisms of such arms are under debate. The two leading hypotheses -- com…
The search for disks or planetary objects around directly imaged companions: A candidate around DH Tau B
C. Lazzoni, A. Zurlo, S. Desidera +45
In recent decades, thousands of substellar companions have been discovered with both indirect and direct methods of detection. In this paper, we focus our attention on substellar c…
18-year long monitoring of the evolution of H2O vapor in the stratosphere of Jupiter with the Odin space telescope
B. Benmahi, T. Cavalié, M. Dobrijevic +14
Comet Shoemaker-Levy 9 impacted Jupiter in July 1994, leaving its stratosphere with several new species, among them water vapor (H2O). With the aid of a photochemical model H2O can…
Retrieving scattering clouds and disequilibrium chemistry in the atmosphere of HR 8799e
P. Mollière, T. Stolker, S. Lacour +25
Clouds are ubiquitous in exoplanet atmospheres and represent a challenge for the model interpretation of their spectra. Complex cloud models are too numerically costly for generati…
An attempt to detect transient changes in Io's SO2 and NaCl atmosphere
L. Roth, J. Boissier, A. Moullet +15
Io's atmosphere is predominately SO2 sustained by a combination of volcanic outgassing and sublimation. The loss from the atmosphere is the main mass source for Jupiter's large mag…
VLT/SPHERE survey for exoplanets around young, early-type stars including systems with multi-belt architectures
M. Lombart, G. Chauvin, P. Rojo +21
Dusty debris disks around pre- and main-sequence stars are potential signposts for the existence of planetesimals and exoplanets. Giant planet formation is therefore expected to pl…
