Abstract:
Planet formation starts in the earliest stages of star formation. Recent observations of exoplanets revealed a diverse planetary system architecture. The key to understanding the observed diversity seems to lie in the physics that govern star and planet formation in the first million years. I will present observational and numerical studies that dwell into the earliest stages of planetary system formation. It has been shown that some of the physics (gravity, rotation, magnetic field, turbulence, radiation) of star formation can be explored by comparing the composition of the environment around young stars to solar system objects. The composition of the dust and gas provides a view into the processing of material as the young protoplanetary disk forms and, also, the formation of the early planet-building materials. Thus, the physics of star formation can only be unveiled by combining astrophysical studies with the chemistry and geochemical processes of planetary bodies. In this talk, I will also discuss future challenges to overcome in star and planet formation.
