Boson star superradiance with spinning effects and in time domain
Fu-Ming Chang, He-Yu Gao, VÃctor Jaramillo +2
Superradiance, the process by which waves are amplified through energy and angular momentum transfer, can also occur in horizonless objects like boson stars, due to both the real s…

Complex structures of boson stars and anisotropic distribution of satellite galaxies
VÃctor Jaramillo, Shuang-Yong Zhou
We construct and explore the complex structures of boson stars, drawing inspiration from similar configurations of non-topological solitons in Minkowski space. These "molecular sta…

Dipoles and chains of solitons in the Friedberg-Lee-Sirlin model
VÃctor Jaramillo, Shuang-Yong Zhou
We construct static axisymmetric multisolitons in the Einstein-Friedberg-Lee-Sirlin model. This theory features a complex scalar field which gains mass through its interaction with…
