The Barnard's Star Planetary System: Stability, Composition, and Evolution of Four Sub-Earth Exoplanets
Xander Byrne, Claire Marie Guimond, Amy Bonsor +3
Barnard's Star is the nearest single star to the Sun (1.8 pc), and hosts four recently-discovered planets. The star also has well-characterized stellar abundances of important rock…
Machine-learning clustering of close-in exoplanet populations: links to pebble accretion
Yi Duann, Anders Johansen, Haiyang S. Wang +1
Close-in exoplanets exhibit a wide range of orbital architectures and physical properties shaped by both formation conditions and migration processes. Although population-synthesis…
Origin and characterization of super-Earths and sub-Neptunes
Léna Parc, Julia Venturini, François Bouchy +6
Super-Earths and sub-Neptunes represent the most common class of exoplanets discovered to date in our galaxy, yet they have no direct analogues in the Solar System. Since 2014, res…
Chemical Abundances Shape History (CASH). I. A Link between Giant Planets Orbital Periods and Host Stellar C/O Ratios
Ruisheng Zhang, Ji-Wei Xie, Mengrui Pan +5
The chemical abundance of host stars plays a pivotal role in shaping the formation history of planetary systems, yet the influence of elements beyond iron remains poorly understood…
Database of Candidate Targets for the LIFE Mission
Franziska Menti, José A. Caballero, Mark C. Wyatt +11
We present the database of potential targets for the Large Interferometer For Exoplanets (LIFE), a space-based mid-infrared nulling interferometer mission proposed for the Voyage 2…
Large Interferometer For Exoplanets (LIFE). XIV. Finding terrestrial protoplanets in the galactic neighborhood
Lorenzo Cesario, Tim Lichtenberg, Eleonora Alei +62
The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization to distances from th…
