Planet Formation through Sequential Accretion
Doug Lin (UCSC) - 6 Feb at 12:00 noon
Based on the data from solar system exploration, observations of
protostellar and debris disks, radial velocity searches and transit
observations of extra solar planets, we examine several important
processes which determine the ubiquity, mass and kinematic distribution
of gas giant planets in terms of the sequential accretion scenario. I
report here some recent progress in our investigations on the survival of
protoplanetary embryos, the onset of efficient gas accretion, the
asymptotic mass, and the extent of migration of gas giant planets.
I will also discuss some aspects of post formation dynamical evolution
which may determine the dynamical configuration of emerging planetary
systems. Finally, I will offer some predictions which can be used to
distinguish the sequential accretion and gravitational instability
scenarios of gas giant planet formation and suggest some key observations
which may place constraints on the relative efficiency of various relevent
physical processes.
The seminar will be held in 544 Campbell Hall.
