Dynamics of kinks in a traversable wormhole
Tian-Chi Ma, Hai-Qing Zhang
We investigate the dynamics of spherically symmetric radial domain walls (or kinks) in a traversable Simpson-Visser wormhole. By solving the scalar field in a double-well potential…

Bayesian Analysis of Massive Boson Star Models for Sagittarius A* Using Near-Infrared Astrometry Data
Xiangyu Wang, Tian-chi Ma, Minyong Guo +1
Assuming that the compact source at the Galactic center, Sagittarius A*, is a massive boson star, we fit the near-infrared flare astrometry data. We consider 12 discrete boson star…

Radial kinks in the boson stars
Tian-Chi Ma, Xiang-Yu Wang, Hai-Qing Zhang
In this work, we study the time evolution of radial kinks in the background of boson stars. In particular, we consider two types of boson stars: the massive boson star and the soli…
