Terrestrial Exoplanet Internal Structure Constraints Enabled by Comprehensive Host Star Characterization Reveal That Terrestrial Planets in Mean Motion Resonances Are Water Rich

The Astrophysical Journal
Exoplanet mass and radius inferences fundamentally rely on host star mass and radius inferences. Despite the importance of host star mass, radius, and elemental abundance inferences for the derivation of exoplanet internal structure constraints ...

Chemical Mapping of Temperate Sub-Neptune Atmospheres: Constraining the Deep Interior H2O/H2 Ratio from the Atmospheric CO2/CH4 Ratio

The Astrophysical Journal Letters
Understanding the planetary envelope composition of sub-Neptune-type exoplanets is challenging due to the inherent degeneracy in their interior composition scenarios.

Insight into the Formation of β Pic b through the Composition of Its Parent Protoplanetary Disk as Revealed by the β Pic Moving Group Member HD 181327

The Astronomical Journal
It has been suggested that β Pic b has a supersolar metallicity and subsolar C/O ratio. Assuming solar carbon and oxygen abundances for the star β Pic and therefore the planet’s parent protoplanetary disk, β Pic b’s C/O ratio suggests that it formed via ...

TOI-880 is an Aligned, Coplanar, Multiplanet System

The Astronomical Journal
Although many cases of stellar spin–orbit misalignment are known, it is usually unclear whether a single planet’s orbit was tilted or if the entire protoplanetary disk was misaligned.

Cloud formation in 3D exoplanet atmospheres

As result of formation and evolution processes, exoplanets can have very different properties, e.g. giant gas planets, rocky planets, mini-neptunes and possibly carbon-rich planets. The understanding of these objects is, to a large extent, hampered by clouds obscuring their atmospheres. Clouds play a key role for the atmospheric dynamics and chemistry,

Formation of stars, substellar objects and exoplanets : Observations of multiplicity [PDF]

, 2011
Many nearby stars are part of a binary or multiple system. Details about their history are preserved in their multiplicity characteristics, and observations of binary/multiple star systems provide a way to measure fundamental physical properties of the stars as well as clues to their formation and evolution.

Planet Mass Function around M Stars at 1–10 au: A Plethora of Sub-Earth Mass Objects

The Astrophysical Journal
Small planets (≲1 M _⊕ ) at intermediate orbital distances (∼1 au) represent an uncharted territory in exoplanetary science. The upcoming microlensing survey by the Nancy Grace Roman Space Telescope will be sensitive to objects as light as Ganymede and ...
