The origin of the solar system as viewed from star formation / Dr Daniel Harsono(Institute of Astronomy and Astrophysics, Academia Sinica) As the number of discovered exoplanets grows, the more we understand how stars and planets form and evolve. Yet, one of the major questions is how this picture fits into the formation of our own Solar System. Models of the young solar nebula, the disk that formed our planetary system, suggest that the chemical composition of the material was reset on the way to the disk. While dust observations reveal the substructure in disks around other stars, it is the chemical structure that can trace the on-going planet formation to connect with the origin of the Solar System. I will present both observations and models of star and planet formation to understand the disk formation process and its implications on the early stages of planet formation and the origin of the Solar System.
