The enigma of planetesimal formation - Orkan Umurhan (SETI Talks)
Δημοσιεύτηκε στις 8 Απρ 2016
The
riddle of planet formation is a key question in solar system studies.
Models of the disk formation process show that there are regions where
the disk can be turbulent, and regions where it is dynamically quiet.
The quiet zones are called 'Dead Zones'.
The implication that
Dead Zones are widespread in planet forming protoplanetary disks has
sparked renewed interest in assessing the dynamical state of these Dead
Zone objects.
In this talk Dr. Umurhan will review the basic
problems relating to the dynamical activity of cold protoplanetary
disks, which will include a review of various recently identified
turbulence generating mechanisms and how they bear upon the assembly of
planetesimals and the formation of our Earth, our solar system and
countless other disk systems across the universe.
