A detailed overview of the knowledge gaps in our understanding of the heliospheric interaction with the largely unexplored Very Local Interstellar Medium (VLISM) are provided …
Geochemical and astronomical evidence demonstrates that planet formation occurred in two spatially and temporally separated reservoirs. The origin of this dichotomy is unknown. We …
Context. The explosion of observational data on exoplanets gives many constraints on theoretical models of planet formation and evolution. Observational data probe very large …
Abstract The Solar System's orbital structure is thought to have been sculpted by an episode of dynamical instability among the giant planets,,–. However, the instability trigger and timing …
Context. Planetary formation and evolution is a combination of multiple interlinked processes. Constraining the mechanisms observationally requires statistical comparison to …
