JWST-SUPER I: New insights into irradiated warm Neptunes atmospheres from MIRI observations of HD 106315 c
A. Dyrek, R. Waters, S. -M. Tsai +17
Sulphur-bearing molecules have recently emerged as powerful tracers of atmospheric photochemistry in exoplanets observed with JWST. In several warm giant planets, SO has been d…
Self-consistent 1D modelling of Jupiter's upper atmosphere as an exoplanet analogue
Nils-Martin Robeling, Sudeshna Boro Saikia, Gwenaëlle Van Looveren +5
Jupiter's upper atmosphere provides a real-world laboratory for validating first-principles models of giant gaseous exoplanets and for constraining the key physical processes that…
CHEOPS photometry from 2024 reveals a reversal in the transit-timing variations of AU Mic c
Z. Garai, Gy. M. Szabó, D. Gandolfi +90
We present new CHEOPS transit observations of AU Mic b and AU Mic c obtained between June and September 2024, extending the baseline of transit-timing measurements of this young pl…
Stellar impact on exoplanetary atmospheric evolution and habitability
Antígona Segura, Manuel Güdel, Konstantin Herbst +4
This chapter will review the deep connection of planetary habitability and stellar irradiation. We present the long-term stellar evolution as one of the drivers of atmospheric esca…
An Ultra-Short Period Super-Earth and a Sub-Neptune Orbiting the K dwarf TOI-4311
Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrew Collier Cameron +95
We report the discovery and characterisation of the multi-planetary system around TOI-4311, a K dwarf kinematically between the Galactic thick disk and Hercules stream. TOI-4311 ho…
Information content of JWST transmission spectroscopy of the exoplanet HAT-P-12b from the optical to the mid-infrared
L. Heinke, M. Min, J. Bouwman +18
The James Webb Space Telescope (JWST) provides low- to medium-resolution spectra with unprecedented precision and broad near- to mid-infrared wavelength coverage, enabling detailed…
Characterisation of the Warm-Jupiter TOI-1130 system with CHEOPS and photo-dynamical approach
L. Borsato, D. Degen, A. Leleu +93
Among the thousands of exoplanets discovered to date, approximately a few hundred gas giants on short-period orbits are classified as "lonely" and only a few are in a multi-planet…
Photo-dynamical characterisation of the TOI-178 resonant chain
A. Leleu, J. -B. Delisle, L. Delrez +104
The TOI-178 system consists of a nearby late K-dwarf transited by six planets in the super-Earth to mini-Neptune regime, with radii ranging from 1.2 to 2.9 earth radius and orbital…
Precise characterisation of HD 15337 with CHEOPS: a laboratory for planet formation and evolution
N. M. Rosário, O. D. S. Demangeon, S. C. C. Barros +90
We aim to constrain the internal structure and composition of HD 15337 b and c, two short-period planets situated on opposite sides of the radius valley, using new transit photomet…
Dust growth and pebble formation in the initial stages of protoplanetary disk evolution
Eduard Vorobyov, Igor Kulikov, Vardan Elbakyan +2
Aims. The initial stages of planet formation may start concurrently with the formation of a gas-dust protoplanetary disk. This makes the study of the earliest stages of protoplanet…
A resonant sextuplet of sub-Neptunes transiting the bright star HD 110067
R. Luque, H. P. Osborn, A. Leleu +149
Planets with radii between that of the Earth and Neptune (hereafter referred to as sub-Neptunes) are found in close-in orbits around more than half of all Sun-like stars. Yet, thei…
CHEOPS observations of KELT-20 b/MASCARA-2 b: An aligned orbit and signs of variability from a reflective dayside
V. Singh, G. Scandariato, A. M. S. Smith +87
Occultations are windows of opportunity to indirectly peek into the dayside atmosphere of exoplanets. High-precision transit events provide information on the spin-orbit alignment…
SO2, silicate clouds, but no CH4 detected in a warm Neptune
Achrene Dyrek, Michiel Min, Leen Decin +44
WASP-107b is a warm (~740 K) transiting planet with a Neptune-like mass of ~30.5 Earth masses and Jupiter-like radius of ~0.94 Jupiter radius, whose extended atmosphere is eroding.…
Imaging detection of the inner dust belt and the four exoplanets in the HR8799 system with JWST's MIRI coronagraph
Boccaletti A., Mâlin M., Baudoz P. +35
The multi planet system HR8799 is the first target observed with MIRI's coronagraphs as part of the MIRI-EC Guaranteed Time Observations exoplanets programme in Nov. 2022. We obtai…
Water in the terrestrial planet-forming zone of the PDS 70 disk
G. Perotti, V. Christiaens, Th. Henning +42
Terrestrial and sub-Neptune planets are expected to form in the inner (AU) regions of protoplanetary disks. Water plays a key role in their formation, although it is yet uncl…
A rich hydrocarbon chemistry and high C to O ratio in the inner disk around a very low-mass star
B. Tabone, G. Bettoni, E. F. van Dishoeck +43
Carbon is an essential element for life but how much can be delivered to young planets is still an open question. The chemical characterization of planet-forming disks is a crucial…
The gas disk: Evolution and chemistry
Ch. Rab, C. Baldovin-Saavedra, O. Dionatos +2
Protoplanetary disks are the birthplaces of planetary systems. The evolution of the star-disk system and the disk chemical composition determines the initial conditions for planet…
Astrophysical Conditions for Planetary Habitability
M. Guedel, R. Dvorak, N. Erkaev +7
With the discovery of hundreds of exoplanets and a potentially huge number of Earth-like planets waiting to be discovered, the conditions for their habitability have become a focal…
Escape of the martian protoatmosphere and initial water inventory
N. V. Erkaev, H. Lammer, L. Elkins-Tanton +8
Latest research in planet formation indicate that Mars formed within a few million years (Myr) and remained a planetary embryo that never grew to a more massive planet. It can also…
