Young planets under extreme UV irradiation. I. Upper atmosphere modelling of the young exoplanet K2-33b
D. Kubyshkina, M. Lendl, L. Fossati +4
The K2-33 planetary system hosts one transiting ~5 R_E planet orbiting the young M-type host star. The planet's mass is still unknown, with an estimated upper limit of 5.4 M_J. The…
Distinguishing the albedo of exoplanets from stellar activity
L. M. Serrano, S. C. C. Barros, M. Oshagh +5
Light curves show the flux variation from the target star and its orbiting planets as a function of time. In addition to the transit features created by the planets, the flux also…
A Comparison of Simulated JWST Observations Derived from Equilibrium and Non-Equilibrium Chemistry Models of Giant Exoplanets
Sarah D. Blumenthal, Avi M. Mandell, Eric Hébrard +4
We aim to see if the difference between equilibrium and disequilibrium chemistry is observable in the atmospheres of transiting planets by the James Webb Space Telescope (JWST). We…
Lyα Absorption at Transits of HD 209458b: A Comparative Study of Various Mechanisms Under Different Conditions
M. L. Khodachenko, I. F. Shaikhislamov, H. Lammer +7
To shed more light on the nature of the observed Lyα absorption during transits of HD 209458b and to quantify the major mechanisms responsible for the production of fast hydrogen a…

An Impacting Descent Probe for Europa and the other Galilean Moons of Jupiter
P. Wurz, D. Lasi, N. Thomas +10
We present a study of an impacting descent probe that increases the science return of spacecraft orbiting or passing an atmosphere-less planetary body of the solar system, such as…
Exocomets in the Proxima Centauri system and their importance for water transport
Richard Schwarz, Akos Bazso, Nikolaos Georgakarakos +7
The scenario and efficiency of water transport by icy asteroids and comets are still amongst the most important unresolved questions of planetary systems. A better understanding of…
- A tool for multiband light curve modeling of planetary transits and stellar spots
Ines G. Juvan, M. Lendl, P. E. Cubillos +5
Several studies have shown that stellar activity features, such as occulted and non-occulted starspots, can affect the measurement of transit parameters biasing studies of transit…
Magma oceans and enhanced volcanism on TRAPPIST-1 planets due to induction heating
K. G. Kislyakova, L. Noack, C. P. Johnstone +6
Low-mass M stars are plentiful in the Universe and often host small, rocky planets detectable with the current instrumentation. Recently, seven small planets have been discovered o…
Evidence for the formation of comet 67P/Churyumov-Gerasimenko through gravitational collapse of a bound clump of pebbles
Jürgen Blum, Bastian Gundlach, Maya Krause +19
The processes that led to the formation of the planetary bodies in the Solar System are still not fully understood. Using the results obtained with the comprehensive suite of instr…
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…
An Algorithm to Compress Line-transition Data for Radiative-transfer Calculations
Patricio Cubillos
Molecular line-transition lists are an essential ingredient for radiative-transfer calculations. With recent databases now surpassing the billion-lines mark, handling them has beco…
Aerosol Constraints on the Atmosphere of the Hot Saturn-mass planet WASP-49b
Patricio Cubillos, Luca Fossati, Nikolai Erkaev +6
The strong, nearly wavelength-independent absorption cross section of aerosols produces featureless exoplanet transmission spectra, limiting our ability to characterize their atmos…
Catalog of fine-structured electron velocity distribution functions Part 1: Antiparallel magnetic-field reconnection (Geospace Environmental Modeling case)
Philippe-A. Bourdin
To understand the essential physics needed to reproduce magnetic reconnection events in 2.5-D particle-in-cell (PIC) simulations, we revisit the Geospace Environmental Modeling (GE…
Rosetta photoelectron emission and solar ultraviolet flux at comet 67P
Fredrik L. Johansson, E. Odelstad, J. J. P. Paulsson +10
The Langmuir Probe instrument on Rosetta monitored the photoelectron emission cur- rent of the probes during the Rosetta mission at comet 67P/Churyumov-Gerasimenko, in essence acti…
The Castalia Mission to Main Belt Comet 133P/Elst-Pizarro
C. Snodgrass, G. H. Jones, H. Boehnhardt +41
We describe Castalia, a proposed mission to rendezvous with a Main Belt Comet (MBC), 133P/Elst-Pizarro. MBCs are a recently discovered population of apparently icy bodies within th…
