Stabilization of the Shear Instability in a Dust Layer of a Protoplanetary Disk and Possible Formation of Planetesimals due to Gravitational Fragmentation of the Dust Layer

Naoki Ishitsu, Minoru Sekiya

We show that the planetesimal formation due to the gravitational fragmentation of a dust layer in a protoplanetary disk is possible. The dust density distribution in the dust layer…
