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}…
Stable stratification promotes multiple zonal jets in a turbulent Jovian dynamo model
T. Gastine, J. Wicht
The ongoing NASA's Juno mission puts new constraints on the internal dynamics of Jupiter. Data gathered by its onboard magnetometer reveal a dipole-dominated surface magnetic field…
1D atmospheric study of the temperate sub-Neptune K2-18b
Doriann Blain, Benjamin Charnay, Bruno Bézard
The atmospheric composition of exoplanets with masses between 2 and 10 M is poorly understood. In that regard, the sub-Neptune K2-18b, which is subject to Earth-like stell…
Phase reddening on asteroid Bennu from visible and near-infrared spectroscopy
S. Fornasier, P. H. Hasselmann, J. D. P Deshapriya +10
The NASA mission OSIRIS-REx has been observing near-Earth asteroid (101955) Bennu in close proximity since December 2018. In this work, we investigate spectral phase reddening -- t…
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…
ARES IV: Probing the atmospheres of the two warm small planets HD 106315 c and HD 3167 c with the HST/WFC3 camera
Gloria Guilluy, Amélie Gressier, Sam Wright +27
We present an atmospheric characterization study of two medium sized planets bracketing the radius of Neptune: HD 106315 c (R=4.98 0.23 R) and HD 3167 c…
Loss and fractionation of noble gas isotopes and moderately volatile elements from planetary embryos and early Venus, Earth and Mars
H. Lammer, M. Scherf, H. Kurokawa +12
Here we discuss the current state of knowledge on how atmospheric escape processes can fractionate noble gas isotopes and moderately volatile rock-forming elements that populate pr…
Formation and dynamics of water clouds on temperate sub-Neptunes: The example of K2-18b
Benjamin Charnay, Doriann Blain, Bruno Bézard +3
Hubble (HST) spectroscopic transit observations of the temperate sub-Neptune K2-18b were interpreted as the presence of water vapour with potential water clouds. 1D modelling studi…
Methane as a dominant absorber in the habitable-zone sub-Neptune K2-18 b
Bruno Bézard, Benjamin Charnay, Doriann Blain
In their Letter, Tsiaras et al. reported the detection of water vapour in the atmosphere of K2-18 b, an exoplanet of 7 to 10 Earth masses located in the habitable zone of an M-dwar…
The detection of solid phosphorus and fluorine in the dust from the coma of comet 67P/Churyumov-Gerasimenko
Esko Gardner, Harry J. Lehto, Kirsi Lehto +7
Here, we report the detection of phosphorus and fluorine in solid particles collected from the inner coma of comet 67P/Churyumov-Gerasimenko measured with the COmetary Secondary Io…
A stringent upper limit of the PH abundance at the cloud top of Venus
T. Encrenaz, T. K. Greathouse, E. Marcq +7
Following the announcement of the detection of phosphine (PH) in the cloud deck of Venus at millimeter wavelengths, we have searched for other possible signatures of this molec…
A physical model for the magnetosphere of Uranus at solstice time
Filippo Pantellini
Uranus is the only planet in the Solar System whose rotation axis and orbital plane are nearly parallel to each other. Uranus is also the planet with the largest angle between the…
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…
Direct confirmation of the radial-velocity planet Pic c
M. Nowak, S. Lacour, A. -M. Lagrange +90
Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period,…
