WALTzER: Wide-band Atmospheric Laboratory for Transiting Exoplanet Research
A. G. Sreejith, L. Fossati, M. Lendl +81
Understanding the origin and evolution of planetary atmospheres, and the connection between their lower and upper atmospheric layers, remains a fundamental challenge in exoplanet s…
Weighing the mass of LHS 3844 b
Alejandro Hacker, Nicola Astudillo-Defru, Rodrigo F. Díaz +7
Context: LHS 3844 b (TOI-136 b) is a ultra short-period, Earth-size exoplanet detected by TESS. It is one of the most favourable object for atmospheric characterisation and the stu…
Fundamentals of interior modelling and challenges in the interpretation of observed rocky exoplanets
Philipp Baumeister, Francesca Miozzi, Claire Marie Guimond +7
Most our knowledge about rocky exoplanets is based on their measure of mass and radius. These two parameters are routinely measured and are used to categorise different populations…
Limits on forming coreless terrestrial worlds in the TRAPPIST-1 system
Dongyang Huang, Caroline Dorn
With seven temperate Earth-sized planets revolving around an ultracool red dwarf, the nearby TRAPPIST-1 system offers a unique opportunity to verify models of exoplanet composition…
The cosmochemistry of planetary systems
Martin Bizzarro, Anders Johansen, Caroline Dorn
Planets form and obtain their compositions from the leftover material present in protoplanetary disks of dust and gas surrounding young stars. The chemical make-up of a disk influe…
A primordial radius valley as a consequence of planet formation
Jesper Nielsen, Anders Johansen, Komal Bali +1
The radius distribution of close-in planets has been observed to have a bimodal distribution with a dearth of planets around ~1.5-2.0 commonly referred to as the ''radiu…
Linking the primordial composition of planet building disks to the present-day composition of rocky exoplanets
V. Adibekyan, M. Deal, C. Dorn +16
The composition of rocky planets is strongly driven by the primordial materials in the protoplanetary disk, which can be inferred from the abundances of the host star. Understandin…
Chapter 10031. Surfaces and Interiors
Lena Noack, Caroline Dorn, Philipp Baumeister
In the last 15 years, since the discovery of the first low-mass planets beyond the solar system, there has been tremendous progress in understanding the diversity of (super-)Earth…
From super-Earths to sub-Neptunes: Observational constraints and connections to theoretical models
Léna Parc, François Bouchy, Julia Venturini +2
We have updated the PlanetS catalog of transiting planets with precise and robust mass and radius measurements and use this catalog to explore mass-radius (M-R) diagrams. On the on…
JWST Reveals CH, CO, and HO in a Metal-rich Miscible Atmosphere on a Two-Earth-Radius Exoplanet
Björn Benneke, Pierre-Alexis Roy, Louis-Philippe Coulombe +28
Even though sub-Neptunes likely represent the most common outcome of planet formation, their natures remain poorly understood. In particular, planets near 1.5-2.5 often…
Discovery of two warm mini-Neptunes with contrasting densities orbiting the young K3V star TOI-815
Angelica Psaridi, Hugh Osborn, François Bouchy +130
We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal i…
A remnant planetary core in the hot-Neptune desert
David J. Armstrong, Théo A. Lopez, Vardan Adibekyan +91
The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of plan…
Threshold radii of volatile-rich planets
Michael Lozovsky, Ravit Helled, Caroline Dorn +1
Constraining the planetary composition is essential for exoplanetary characterization. In this paper, we use a statistical analysis to determine the characteristic maximum (thresho…
From stellar to planetary composition: Galactic chemical evolution of Mg/Si mineralogical ratio
V. Adibekyan, N. C. Santos, P. Figueira +6
The main goal of this work is to study element ratios that are important for the formation of planets of different masses. We study potential correlations between the existence of…
Constraining planet structure from stellar chemistry: the cases of CoRoT-7, Kepler-10, and Kepler-93
N. C. Santos, V. Adibekyan, C. Mordasini +10
We explore the possibility that the stellar relative abundances of different species can be used to constrain the bulk abundances of known transiting rocky planets. We use high res…
