Phase Modeling of the TRAPPIST-1 Planetary Atmospheres
Stephen R. Kane, Tiffany Jansen, Thomas Fauchez +2
Transiting compact multi-planet systems provide many unique opportunities to characterize the planets, including studies of size distributions, mean densities, orbital dynamics, an…
Spectral binning of precomputed correlated-k coefficients
Jérémy Leconte
With the major increase in the volume of the spectroscopic line lists needed to perform accurate radiative transfer calculations, disseminating accurate radiative data has become a…
Influence of planetary gas accretion on the shape and depth of gaps in protoplanetary discs
C. Bergez-Casalou, B. Bitsch, A. Pierens +2
It is widely known that giant planets have the capacity to open deep gaps in their natal gaseous protoplanetary discs. It is unclear, however, how gas accretion onto growing planet…
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…
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…
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…
Survivor bias: divergent fates of the Solar System's ejected vs. persisting planetesimals
Sean N. Raymond, Nathan A. Kaib, Philip J. Armitage +1
The orbital architecture of the Solar System is thought to have been sculpted by a dynamical instability among the giant planets. During the instability a primordial outer disk of…
The nature and origins of sub-Neptune size planets
Jacob L. Bean, Sean N. Raymond, James E. Owen
Planets intermediate in size between the Earth and Neptune, and orbiting closer to their host stars than Mercury does the Sun, are the most common type of planet revealed by exopla…
Dry Late Accretion inferred from Venus' coupled atmosphere and internal evolution
C. Gillmann, G. J. Golabek, S. N. Raymond +4
The composition of meteoritic material delivered to the terrestrial planets after the end of core formation as late accretion remains contentious. Because the evolution of Venus' a…
Influence of the ice structure on the soft UV photochemistry of PAHs embedded in solid water
J. A. Noble, E. Michoulier, C. Aupetit +1
The UV photoreactivity of polycyclic aromatic hydrocarbons (PAHs) in porous amorphous solid water has long been known to form both oxygenated photoproducts and photofragments. The…
ALMA and VLA Observations of EX Lupi in its Quiescent State
Jacob Aaron White, Á. Kóspál, A. G. Hughes +15
Extreme outbursts in young stars may be a common stage of pre-main-sequence stellar evolution. These outbursts, caused by enhanced accretion and accompanied by increased luminosity…
Born eccentric: constraints on Jupiter and Saturn's pre-instability orbits
Mattthew S. Clement, Sean N. Raymond, Nathan A. Kaib +3
An episode of dynamical instability is thought to have sculpted the orbital structure of the outer solar system. When modeling this instability, a key constraint comes from Jupiter…
MOA-2009-BLG-319Lb: A Sub-Saturn Planet Inside the Predicted Mass Desert
Sean K. Terry, Aparna Bhattacharya, David P. Bennett +10
We present an adaptive optics (AO) analysis of images from the Keck-II telescope NIRC2 instrument of the planetary microlensing event MOA-2009-BLG-319. The 10 year baseline b…
The origins of nearly coplanar, non-resonant systems of close-in super-Earths
Leandro Esteves, André Izidoro, Sean N. Raymond +1
Some systems of close-in "super-Earths" contain five or more planets on non-resonant but compact and nearly coplanar orbits. The Kepler-11 system is an iconic representative of thi…
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…
A review of possible planetary atmospheres in the TRAPPIST-1 system
Martin Turbet, Emeline Bolmont, Vincent Bourrier +4
TRAPPIST-1 is a fantastic nearby (~39.14 light years) planetary system made of at least seven transiting terrestrial-size, terrestrial-mass planets all receiving a moderate amount…
TRAPPIST-1: Global Results of the Spitzer Exploration Science Program {\it Red Worlds}
Elsa Ducrot, M. Gillon, L. Delrez +18
With more than 1000 hours of observation from Feb 2016 to Oct 2019, the Spitzer Exploration Program Red Worlds (ID: 13067, 13175 and 14223) exclusively targeted TRAPPIST-1, a nearb…
Obliquity of an Earth-like planet from frequency modulation of its direct imaged lightcurve: mock analysis from general circulation model simulation
Yuta Nakagawa, Takanori Kodama, Masaki Ishiwatari +8
Direct-imaging techniques of exoplanets have made significant progress recently, and will eventually enable to monitor photometric and spectroscopic signals of earth-like habitable…
Atmospheric chemistry on Uranus and Neptune
J. I. Moses, T. Cavalie, L. N. Fletcher +1
Comparatively little is known about atmospheric chemistry on Uranus and Neptune, because remote spectral observations of these cold, distant ``Ice Giants'' are challenging, and eac…
No evidence for interstellar planetesimals trapped in the Solar System
A. Morbidelli, K. Batygin, R. Brasser +1
In two recent papers published in MNRAS, Namouni and Morais (2018, 2020) claimed evidence for the interstellar origin of some small Solar System bodies, including i) objects in ret…
