Numerical simulations of oscillating soliton stars: Excited states in spherical symmetry and ground state evolutions in 3D

Excited state soliton stars are studied numerically for the first time. The stability of spherically symmetric $S$-branch excited state oscillatons under radial perturbations is investigated using a 1D code. We find that these stars are inherently unstable either migrating to the ground state or col... View More
