Abstract:

The measured masses and orbits of the 175 known exoplanets
within 200 pc provide constraints on the formation and
dynamics of planetary systems.  A new domain of planets from
1-15 Earth masses, not represented in our Solar System, is
becoming accessible observationally.  Several planets under
20 Earth-masses have recently been detected.  The formation
and internal structures of rock and rock-ice planets are
being modeled.  Construction has begun of a 2.4-m "Automated
Planet Finder" telescope at Lick Obs. that will be dedicated
to detecting Super-Earths.
