Magnetic effect on the evolution of an eccentric and inclined orbit
Xing Wei
We provide a method to calculate the evolution of an eccentric and inclined orbit under the magnetic effect. Taking the unipolar interaction as an example, we study both coplanar a…
Energy partition in magnetohydrodynamic turbulence
Xing Wei
We use a simple and straightforward method to derive the energy partition in magnetohydrodynamics (MHD) turbulence that was first studied by Lee and then more rigorously by Chandra…
Gravitational instability in protoplanetary disk with cooling: 2D global analysis
Zehao Su, Xing Wei
Self-gravity is important in protoplanetary disks for planet formation through gravitational instability (GI). We study the cooling effect on GI in a thin two-dimensional protoplan…
Coupling of dynamical tide and orbital motion
Xing Wei
Dynamical tide consists of various waves that can resonate with orbital motion. We test this coupling of dynamical tide and orbital motion using a simple two-dimensional shallow wa…
Construct a realistic stellar model with polytropic relation
Xing Wei
The aim of this study is to construct a simple stellar model with non-uniform polytropic index. We find that the Emden equation cannot deal with the polytrope gas sphere with non-u…
