Beschreibung
Due to the absence of a reliable rock record from the Hadean eon, our understanding of the environment that gave rise to life on our own planet is clouded. Current and upcoming exoplanet surveys, however, significantly widen our view of the distribution and variability of rocky planets and their chemical inventories, giving opportunity to test scenarios of early planetary evolution and atmospheric formation. I will describe how rocky exoplanets in a partially or fully molten state open a novel window into on the earliest, high-temperature evolutionary regime of rocky worlds. Increasing reconnaissance of high-temperature super-Earths will enable us to infer the early climatic and geodynamic evolution of temperate rocky worlds, providing crucial information on the environmental context of the origins of life on Earth and are the next key step toward the characterisation of prebiotic and potentially habitable exoplanets.
