The Effect Of Collisional Erosion On The Composition Of Earth-analog Planets In Grand Tack models: Implications For The Formation Of The Earth
Impact-induced erosion of the Earth’s early crust during accretion of terrestrial bodies can significantly modify the primordial chemical composition of the Bulk Silicate Earth (BSE, that is, the composition of […]

A Radiative-Convective Model For Terrestrial Planets With Self-Consistent Patchy Clouds
Clouds are ubiquitous – they arise for every solar system planet that possesses an atmosphere and have also been suggested as a leading mechanism for obscuring spectral features in exoplanet […]
