Title: Formation of Planets at Home and Abroad: From Disks to Earths and Super-Earths Abstract: Recent observations by the Kepler space telescope have led to the discovery of more than 4000 exoplanet candidates consisting of many systems with Earth- to Neptune-sized objects that reside well inside the orbit of Mercury around their respective host stars. How and where this new class of planets formed is one of the major unanswered questions in planet formation. I will present recent results concerning initial disk masses and new models that self-consistently treat nebular gas accretion onto rocky cores and the subsequent evolution of gas envelopes due to cooling and photo-evaporation during and after the dispersal of protoplanetary disks. I will conclude with discussing their implications for terrestrial planet formation in our Solar System and the origin of close-in Super- Earths and Mini-Neptunes in exoplanet systems.
