Exoplanet interiors and habitability [PDF]

open access: yesAdvances in Physics: X, 2019
More than 1000 exoplanets with a radius smaller than twice that of the Earth are currently known, mainly thanks to space missions dedicated to the search of exoplanets.

Biological, Equilibrium and Photochemical Signatures of C, N and S Isotopes in the Early Earth and Exoplanet Atmospheres. [PDF]

open access: yesLife (Basel)
The unambiguous detection of biosignatures in exoplanet atmospheres is a primary objective for astrobiologists and exoplanet astronomers. The primary methodology is the observation of combinations of gases considered unlikely to coexist in an atmosphere ...

Large Interferometer For Exoplanets (LIFE). I. Improved exoplanet detection yield estimates for a large mid-infrared space-interferometer mission [PDF]

open access: yesAstronomy & Astrophysics, 2021
One of the long-term goals of exoplanet science is the atmospheric characterization of dozens of small exoplanets in order to understand their diversity and search for habitable worlds and potential biosignatures.

Imaging exoplanets with coronagraphic instruments [PDF]

open access: yesComptes rendus. Physique, 2023
Exoplanetary science is a very active field of astronomy nowadays, with questions still opened such as how planetary systems form and evolve (occurrence, process), why such a diversity of exoplanets is observed (mass, radius, orbital parameters ...

Interpreting the Atmospheric Composition of Exoplanets: Sensitivity to Planet Formation Assumptions [PDF]

open access: yesAstrophysical Journal, 2022
Constraining planet formation based on the atmospheric composition of exoplanets is a fundamental goal of the exoplanet community. Existing studies commonly try to constrain atmospheric abundances, or to analyze what abundance patterns a given ...

A Catalog of Habitable Zone Exoplanets [PDF]

open access: yesAstronomical Journal, 2022
The search for habitable planets has revealed many planets that can vary greatly from an Earth analog environment. These include highly eccentric orbits, giant planets, different bulk densities, relatively active stars, and evolved stars.

Large Interferometer For Exoplanets (LIFE). II. Signal simulation, signal extraction, and fundamental exoplanet parameters from single-epoch observations [PDF]

open access: yesAstronomy & Astrophysics, 2022
The Large Interferometer For Exoplanets (LIFE) initiative is developing the science and a technology roadmap for an ambitious space mission featuring a space-based mid-infrared (MIR) nulling interferometer in order to detect the thermal emission of ...

A compositional link between rocky exoplanets and their host stars [PDF]

open access: yesScience, 2021
Description Compositions of rocky exoplanets The interior compositions of small rocky exoplanets cannot be observed directly but are expected to relate to the composition of the host star. Adibekyan et al. analyzed a sample of rocky exoplanets, inferring

Hidden Water in Magma Ocean Exoplanets [PDF]

open access: yesAstrophysical Journal Letters, 2021
We demonstrate that the deep volatile storage capacity of magma oceans has significant implications for the bulk composition, interior, and climate state inferred from exoplanet mass and radius data.

Reflected Spectroscopy of Small Exoplanets II: Characterization of Terrestrial Exoplanets [PDF]

open access: yesAstronomical Journal, 2022
A space telescope capable of high-contrast imaging has been recognized as the avenue toward finding terrestrial planets around nearby Sun-like stars and characterizing their potential habitability.
