The Great Impersonation: -Solitons as Prototypical Black Hole Microstates
Alexandru Dima, Pierre Heidmann, Marco Melis +2
We analyze a new class of static, smooth geometries in five-dimensional supergravity, dubbed -solitons. They carry the same mass and charges as four-dimensional Reissn…
Extreme mass ratio inspirals around topological stars
Marco Melis, Richard Brito, Paolo Pani
We study a point scalar charge in circular orbit around a topological star, a regular, horizonless soliton emerging from dimensional compactification of Einstein-Maxwell theory in…
Black hole spectroscopy and nonlinear echoes in Einstein-Maxwell-scalar theory
Marco Melis, Fabrizio Corelli, Robin Croft +1
In the context of Einstein-Maxwell-scalar theory with a nonminimal coupling between the electromagnetic and scalar field, we study linear (non)radial perturbations and nonlinear ra…
Nonradial stability of topological stars
Alexandru Dima, Marco Melis, Paolo Pani
Topological stars are regular, horizonless solitons arising from dimensional compactification of Einstein-Maxwell theory in five dimensions, which could describe qualitative proper…
