The Impact-driven Atmospheric Loss of Super-Earths around Different Spectral Types of Host Stars

The Astrophysical Journal
A planet’s mass loss is important for the its formation and evolution. The radius valley (RV) is believed to be triggered by evaporation-induced mass loss.

Reduced Water Loss due to Photochemistry on Terrestrial Planets in the Runaway Greenhouse Phase around Pre-main-sequence M Dwarfs

The Astrophysical Journal
Terrestrial planets currently in the habitable zone around M dwarfs are estimated to have been in runaway greenhouse conditions for up to ∼1 Gyr due to the long-term pre-main-sequence phase of M dwarfs.

The Age and High-energy Environment of the Very Young Transiting Exoplanet TOI 1227b

The Astrophysical Journal
The mid-M star TOI 1227 hosts among the youngest known transiting exoplanets. We have conducted new X-ray imaging and optical spectroscopic observations of TOI 1227 aimed at ascertaining its age and the influence of its high-energy radiation on the ...

Pushing the envelope of exoplanet evolution modelling

, 2021
Propelled by the discovery of the first exoplanet thirty years ago, the scientific community has rallied and made tremendous strides towards a full understand of the formation and evolution of planetary systems. During this period, over 4, 300 confirmed exoplanets have been detected, and the resulting dataset has driven a revolution by allowing for new
