Disk-Planet Interaction Simulations: (I) Baroclinic Generation of Vortensity and Non-Axisymmetric Rossby-Wave-Instability
Shangli Ou, Jianghui Ji, Lin Liu +1
We use a multi-dimensional hydrodynamics code to study the gravitational interaction between an embedded planet and a protoplanetary disk with emphasis on the generation of vortens…
Unexpected Dynamical Instabilities In Differentially Rotating Neutron Stars
Shangli Ou, Joel E. Tohline
A one-armed spiral instability has been found to develop in differentially rotating stellar models that have a relatively stiff, polytropic equation of state and a wide range…
One-armed Spiral Instability in a Low T/|W| Postbounce Supernova Core
Christian D. Ott, Shangli Ou, Joel E. Tohline +1
A three-dimensional, Newtonian hydrodynamic technique is used to follow the postbounce phase of a stellar core collapse event. For realistic initial data we have employed post core…
Nonlinear Development of the Secular Bar-mode Instability in Rotating Neutron Stars
Shangli Ou, Joel E. Tohline, Lee Lindblom
We have modelled the nonlinear development of the secular bar-mode instability that is driven by gravitational radiation-reaction (GRR) forces in rotating neutron stars. In the abs…
