Ergoregion instability in bosonic stars: scalar mode structure, universality, and weakly nonlinear effects
Nils Siemonsen
Ultracompact spinning horizonless spacetimes with ergoregions are subject to the ergoregion instability. We systematically investigate the instability of a massless scalar field in…

Weakly turbulent saturation of the nonlinear scalar ergoregion instability
Nils Siemonsen
We perform time-domain evolutions of the ergoregion instability on a horizonless spinning ultracompact spacetime in scalar theories with potential-type and derivative self-interact…
