Impact of electric charges on chaos in magnetized spacetimes
Daqi Yang, Wenfang Liu, Xin Wu
We consider the motion of test particles around a black hole immersed into a strong external magnetic field modifying the spacetime structure. When the particl…
Parameter constraints from shadows of Kerr-Newman-dS black holes with cloud strings and quintessence
Wen-Fu Cao, Wen-Fang Liu, Xin Wu
The motion of photons around the Kerr-Newman-dS black hole surrounded by quintessence and a cloud of strings is investigated. The existence of the Carter constant leads to that of…
Equivalence between two charged black holes in dynamics of orbits outside the event horizons
Hongxing Zhang, Naying Zhou, Wenfang Liu +1
Using the FermiDirac distribution function, Balart and Vagenas gave a charged spherically symmetric regular black hole, which is a solution of Einstein field equations coupled to a…
Integrability of Kerr-Newman spacetime with cloud strings, quintessence and electromagnetic field
Wenfu Cao, Wenfang Liu, Xin Wu
The dynamics of charged particles moving around a Kerr-Newman black hole surrounded by cloud strings, quintessence and electromagnetic field is integrable due to the presence of a…
Chaos in a Magnetized Modified Gravity Schwarzschild Spacetime
Daqi Yang, Wenfu Cao, Naying Zhou +3
Based on the scalar-tensor-vector modified gravitational theory, a modified gravity Schwarzschild black hole solution has been given in the existing literature. Such a black hole s…
A Note on the Construction of Explicit Symplectic Integrators for Schwarzschild Spacetimes
Naying Zhou, Hongxing Zhang, Wenfang Liu +1
In recent publications, the construction of explicit symplectic integrators for Schwarzschild and Kerr type spacetimes is based on splitting and composition methods for numerical i…
