Redox Hysteresis of Super-Earth Exoplanets from Magma Ocean Circulation [PDF]
Astrophysical Journal Letters, 2021 Internal redox reactions may irreversibly alter the mantle composition and volatile inventory of terrestrial and super-Earth exoplanets and affect the prospects for atmospheric observations. The global efficacy of these mechanisms, however, hinges on the

Revisited mass-radius relations for exoplanets below 120 M⊕ [PDF]
Astronomy & Astrophysics, 2019 The masses and radii of exoplanets are fundamental quantities needed for their characterisation. Studying the different populations of exoplanets is important for understanding the demographics of the different planetary types, which can then be linked ...

Atmospheric regimes and trends on exoplanets and brown dwarfs [PDF]
Research in Astronomy and Astrophysics, 2020 A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance among the first and most accessible planetary layers observed from space, it is closely connected with planetary formation and evolution, surface and interior ...

VaTEST. II. Statistical Validation of 11 TESS-detected Exoplanets Orbiting K-type Stars
The Astronomical Journal, 2023 NASA’s Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission designed to find transiting exoplanets orbiting nearby bright stars. It has identified more than 329 transiting exoplanets, and almost 6000 candidates remain unvalidated. In

Exoplanets as Sub-GeV Dark Matter Detectors. [PDF]
Physical Review Letters, 2020 We present exoplanets as new targets to discover dark matter (DM). Throughout the Milky Way, DM can scatter, become captured, deposit annihilation energy, and increase the heat flow within exoplanets.

Core-powered mass-loss and the radius distribution of small exoplanets [PDF]
, 2017 Recent observations identify a valley in the radius distribution of small exoplanets, with planets in the range $1.5-2.0\,{\rm R}_\oplus$ significantly less common than somewhat smaller or larger planets.

Compositional Diversity of Rocky Exoplanets [PDF]
Elements, 2021 To test whether exoplanets are similar to Earth, knowledge of their host star composition is essential. Stellar elemental abundances and planetary orbital data show that of the ~5,000 known minerals, exoplanetary silicate mantles contain mostly olivine ...

Sculpting the valley in the radius distribution of small exoplanets as a by-product of planet formation: the core-powered mass-loss mechanism. [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Recent observations revealed a bimodal radius distribution of small, short-period exoplanets with a paucity in their occurrence, a radius 'valley', around 1.5-2.0 R⊕.
