*Crash, Boom, Bang:  Giant Impacts & the Formation of Planets at Home and
Abroad.*





*Prof. Hilke Schlichting *Department of Earth, Atmospheric and Planetary
Sciences

Massachusetts Institute of Technology








*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 these close-in
planets formed is one of the major unanswered questions in planet
formation. I will present recent results concerning initial disk masses and
atmospheric mass-loss due to impacts and will discuss their implications
for terrestrial planet formation in our Solar System and the origin of
close-in Super-Earths and Mini-Neptunes.
