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…
Further Evidence for an Elliptical Instability in Rotating Fluid Bars and Ellipsoidal Stars
Shangli Ou, Joel E. Tohline, Patrick M. Motl
Using a three-dimensional nonlinear hydrodynamic code, we examine the dynamical stability of more than twenty self-gravitating, compressible, ellipsoidal fluid configurations that…
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…
An approximate solver for Riemann and Riemann-like Ellipsoidal Configurations
Shangli Ou
We introduce a new technique for constructing three-dimensional (3D) models of incompressible Riemann S-type ellipsoids and compressible triaxial configurations that share the same…
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…
