The Influence of General Relativity on the Spins of Celestial Bodies in Inclined Orbits
Huan-rong Yuan, Ying Wang, Xin Wu +4
Through the Rossiter-McLaughlin effect, several hot Jupiters have been found to exhibit spin-orbit misalignment, and even retrograde orbits. The high obliquity observed in these pl…
Explicit symplectic integrators with adaptive time steps in curved spacetimes
Xin Wu, Ying Wang, Wei Sun +2
Recently, our group developed explicit symplectic methods for curved spacetimes that are not split into several explicitly integrable parts, but are via appropriate time transforma…
Dynamical Stability of Polar Circumbinary Orbits and Planet-Formation in Planetary Disc of 99 Herculis
Ying Wang, Wei Sun, Ji-lin Zhou +2
A possible polar-ring debris disc, the dynamics of which can be described by the outer hierarchical restricted three-body problem, has been detected in 99 Herculis. An empirical fo…
Representation Learning for Continuous Action Spaces is Beneficial for Efficient Policy Learning
Tingting Zhao, Ying Wang, Wei Sun +3
Deep reinforcement learning (DRL) breaks through the bottlenecks of traditional reinforcement learning (RL) with the help of the perception capability of deep learning and has been…
Explicit symplectic methods in black hole spacetimes
Xin Wu, Ying Wang, Wei Sun +2
Many Hamiltonian problems in the Solar System are separable or separate into two analytically solvable parts, and thus give a great chance to the development and application of exp…
Applying explicit symplectic integrator to study chaos of charged particles around magnetized Kerr black hole
Wei Sun, Ying Wang, Fuyao Liu +1
In a recent work of Wu, Wang, Sun and Liu, a second-order explicit symplectic integrator was proposed for the integrable Kerr spacetime geometry. It is still suited for simulating…
Construction of explicit symplectic integrators in general relativity. IV. Kerr black holes
Xin Wu, Ying Wang, Wei Sun +1
In previous papers, explicit symplectic integrators were designed for nonrotating black holes, such as a Schwarzschild black hole. However, they fail to work in the Kerr spacetime…
Construction of explicit symplectic integrators in general relativity. III. Reissner-Nordstrom-(anti)-de Sitter black holes
Ying Wang, Wei Sun, Fuyao Liu +1
We give a possible splitting method to a Hamiltonian for the description of charged particles moving around the Reissner-Nordstrom-(anti)-de Sitter black hole with an external magn…
Construction of explicit symplectic integrators in general relativity. II. Reissner-Nordstrom black holes
Ying Wang, Wei Sun, Fuyao Liu +1
In a previous paper, second- and fourth-order explicit symplectic integrators were designed for a Hamiltonian of the Schwarzschild black hole. Following this work, we continue to t…
Construction of Explicit Symplectic Integrators in General Relativity. I. Schwarzschild Black Holes
Ying Wang, Wei Sun, Fuyao Liu +1
Symplectic integrators that preserve the geometric structure of Hamiltonian flows and do not exhibit secular growth in energy errors are suitable for the long-term integration of N…
Forming Different Planetary Architectures . I . Formation Efficiency of Hot Jupites from High-eccentricity Mechanisms
Ying Wang, Ji-lin Zhou, Liu hui-gen +1
Exoplanets discovered over the last decades have provided a new sample of giant exoplanets, hot Jupiters. For lack of enough materials in current locations of hot Jupiters, they ar…
Transits of Planets with Small Intervals in Circumbinary Systems
Hui-Gen Liu, Ying Wang, Hui Zhang +1
Transit times around single stars can be described well by a linear ephemeris. However, transit times in circumbinary systems are influenced both by the gravitational perturbations…
