Some assembly required: Nature's instruction booklet for planetary migration
Μετάδοση με ζωντανή ροή στις 21 Ιαν 2014
Speaker: Rebekah Dawson, UC Berkeley
Abstract-
We once thought planets formed peacefully in situ in their natal disks
and subsequently followed their orbits like clockwork. However, there is
growing evidence that the typical planetary system forms with "some
assembly required" and undergoes a dynamical rearrangement through
planetary migration processes. The nature of this migration remains
debated, in particular whether the migration is caused by smooth
planet-disk interactions or violent multi-body interactions. Here I
present work toward understanding Nature's instruction booklet for
planetary migration in extra-solar planetary systems and our own solar
system.
