Abstract

Our knowledge on the population of exoplanets and circumstellar disks has increased drastically in the last decades. Yet many processes during the formation of planets, especially in the intermediate size range, are unobservable. This thesis focuses on linking the evolution of a circumstellar disk with a final set of planets in a globally self consistent framework. The number of embryos and their formation in current planet formation models are subject to assumptions and not to physical modeling. This inconsistency currently marks the single largest blind spot in global planet formation modeling. Within four consecutive publications, I present key improvements in global planet formation modeling. Namely the evolution of dust and pebbles, the formation of planetesimals and the formation of planetary embryos. Within this thesis I present a global planet formation model that self-consistently tracks the formation of planets from an initial disk of gas and dust during its entire lifetime. For the first time, this is achieved without far reaching assumptions on initially placed planetesimals or planetary embryos. I show that the disk consistent treatment of planetary embryo formation results in multiple distinct embryo generations during the lifetime of the circumstellar disk. A clear dichotomy between planets that form in different generations is found. The generation from which an embryo originates has far reaching implications on its composition and final planetary properties.
