Universe, 2023 Tidal interaction between a star and a close-in massive exoplanet causes the planetary orbit to shrink and eventually leads to tidal disruption. Understanding orbital decay in exoplanetary systems is crucial for advancing our knowledge of planetary ...

Atmospheres of Rocky Exoplanets [PDF]
, 2021 Rocky planets are common around other stars, but their atmospheric properties remain largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming advances in observing capability, we are poised to characterize the atmospheres of ...

Atmospheric circulation of exoplanets
地球与行星物理论评, 2023 To date, more than 5000 exoplanets and more than 2000 brown dwarfs have been confirmed, which shows rich diversities in many aspects. With the rapid growth of the planet family, both observational and theoretical research on exoplanet atmosphere is ...

Large Interferometer For Exoplanets (LIFE). III. Spectral resolution, wavelength range and sensitivity requirements based on atmospheric retrieval analyses of an exo-Earth [PDF]
Astronomy & Astrophysics, 2021 Temperate terrestrial exoplanets are likely common objects, but their discovery and characterization is very challenging. Concepts for optimized space missions to overcome these challenges are being studied. The LIFE initiative focuses on the development

Mass–Metallicity Trends in Transiting Exoplanets from Atmospheric Abundances of H2O, Na, and K [PDF]
Astrophysical Journal, 2019 Atmospheric compositions can provide powerful diagnostics of formation and migration histories of planetary systems. We investigate constraints on atmospheric abundances of H2O, Na, and K, in a sample of transiting exoplanets using the latest ...

The SPHERE infrared survey for exoplanets (SHINE) [PDF]
Astronomy & Astrophysics, 2020 The SpHere INfrared Exoplanet (SHINE) project is a 500-star survey performed with SPHERE on the Very Large Telescope for the purpose of directly detecting new substellar companions and understanding their formation and early evolution. Here we present an

The CARMENES search for exoplanets around M dwarfs [PDF]
Astronomy & Astrophysics, 2019 Context. Teegarden’s Star is the brightest and one of the nearest ultra-cool dwarfs in the solar neighbourhood. For its late spectral type (M7.0 V), the star shows relatively little activity and is a prime target for near-infrared radial velocity surveys

The nature of the TRAPPIST-1 exoplanets. [PDF]
, 2018 Context. The TRAPPIST-1 system hosts seven Earth-sized, temperate exoplanets orbiting an ultra-cool dwarf star. As such, it represents a remarkable setting to study the formation and evolution of terrestrial planets that formed in the same protoplanetary
