Constraining small planet compositions with catastrophically evaporating rocky planets
Beatriz Campos Estrada (MPIA)
Abstract: The nature and composition of small planets' interiors remain uncertain. Catastrophically evaporating rocky planets provide a unique opportunity to study the composition of small planets. The surface composition of these planets can be constrained via modelling their comet-like tails of dust. In this work we present a new self-consistent model of the dusty tails. We model two catastrophically evaporating planets: KIC 1255 b and K2-22 b. For both planets we find the dust is likely composed of magnesium-iron silicates (olivine and pyroxene), consistent with an Earth-like composition.
