Boson Stars in Dimensions: Stability, Oscillation Frequencies, and Dynamical Evolutions
Gareth Arturo Marks, Abdullah Al Zaif
We construct spherically symmetric boson star solutions in spacetime dimensions, considering the effects of both a quartic self-interaction term and a solitonic p…
Black Hole-Boson Star Binaries: Gravitational Wave Signals and Tidal Disruption
Gareth Arturo Marks, Seppe J. Staelens, Ulrich Sperhake
We present a detailed, fully nonlinear study of binary systems involving one black hole and one boson star, considering the effects of both a quartic self-interaction and a soliton…
Perturbations of Solitonic Boson Stars: Nonlinear Radial Stability and Binding Energy
Gareth Arturo Marks
We study the nonlinear radial stability of boson stars with a solitonic potential across the entire parameter space, focusing especially on families of solutions that support ultra…
Long-term stable nonlinear evolutions of ultracompact black-hole mimickers
Gareth Arturo Marks, Seppe J. Staelens, Tamara Evstafyeva +1
We study the stability of ultracompact boson stars admitting light rings combining a perturbative analysis with 3+1 numerical-relativity simulations with and without symmetry assum…
