CHEOPS observations of the HD 108236 planetary system: a fifth planet, improved ephemerides, and planetary radii [PDF]
Astronomy & Astrophysics, 2021 Context. The detection of a super-Earth and three mini-Neptunes transiting the bright (V = 9.2 mag) star HD 108236 (also known as TOI-1233) was recently reported on the basis of TESS and ground-based light curves. Aims.

The case for studying other planetary magnetospheres and atmospheres in Heliophysics [PDF]
Vol. 55, Issue 3 (Heliophysics 2024 Decadal Whitepapers), 2023 Heliophysics is the field that"studies the nature of the Sun, and how it influences the very nature of space - and, in turn, the atmospheres of planetary bodies and the technology that exists there."However, NASA's Heliophysics Division tends to limit ...

A low accretion efficiency of planetesimals formed at planetary gap edges [PDF]
Astronomy & Astrophysics, 2022 Observations and models of giant planets indicate that such objects are enriched in heavy elements compared to solar abundances. The prevailing view is that giant planets accreted multiple Earth masses of heavy elements after the end of core formation ...

Three planets transiting the evolved star EPIC 249893012: a hot 8.8-M⊕ super-Earth and two warm 14.7 and 10.2-M⊕ sub-Neptunes [PDF]
Astronomy & Astrophysics, 2020 We report the discovery of a new planetary system with three transiting planets, one super-Earth and two sub-Neptunes, that orbit EPIC 249893012, a G8 IV-V evolved star (M⋆ = 1.05 ± 0.05 M⊙, R⋆ = 1.71 ± 0.04 R⊙, Teff = 5430 ± 85 K).

Growth after the streaming instability: The radial distance dependence of the planetary growth [PDF]
Astronomy & Astrophysics, 2022 Streaming instability is hypothesized to be triggered at particular protoplanetary disk locations where the volume density of the solid particles is enriched comparable to that of the gas.

Quantifying the Key Factors Affecting the Escape of Planetary Atmospheres
Astrophysical Journal, 2023 The habitability of Earth-like planets is an increasingly important subject in astrophysics and in planetary sciences. Atmospheric escape plays a vital role in the evolution of the habitability of Earth-like planets.
