Interaction of eccentricity tide and convection
Jiachen Zheng, Xing Wei
Aim. We try to understand the interaction of eccentricity tide and convection in icy satellites. Method. We use the numerical calculation of rotating convection with eccentricity t…
Laplace surface of eccentric orbits around Kerr black hole and black-hole effects on Lidov-Kozai cycles
Haonan Quan, Xing Wei
We study the Laplace surface of eccentric orbits around a Kerr black hole with a companion star. The two relativistic effects (periapsis apsidal precession and Lense-Thirring prece…
Turbulent infall onto class 0 disks as cause of CAI brief condensation episode in the solar system
Jiachen Zheng, Xing Wei, Hongping Deng +2
Calcium-aluminum-rich inclusions (CAIs) in carbonaceous chondritic meteorites are the oldest relics in the solar system. Notably, their radiogenic age feature a brief (100 kyr) con…
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…
An accretion disc with magnetic outflows triggered by a sudden mass accretion event in changing-look active galactic nucleus 1ES 1927+654
Xinwu Cao, Bei You, Xing Wei
1ES 1927+654 was known as a type 2 Seyfert galaxy, which exhibited drastic variability recently in ultraviolet (UV)/optical and X-ray bands. An UV/optical outburst was observed in…
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…
