Two boson stars in equilibrium
P. Cunha, C. Herdeiro, E. Radu +1
We construct and explore the solution space of two non-spinning, mini-boson stars in equilibrium, in fully non-linear General Relativity (GR), minimally coupled to a free, massive,…
Kerr black holes with synchronised Proca hair: lensing, shadows and EHT constraints
Ivo Sengo, Pedro V. P. Cunha, Carlos A. R. Herdeiro +1
We investigate the gravitational lensing by spinning Proca stars and the shadows and lensing by Kerr black holes (BHs) with synchronised Proca hair, discussing both theoretical asp…
Null and timelike circular orbits from equivalent 2D metrics
Pedro V. P. Cunha, Carlos A. R. Herdeiro, João P. A. Novo
The motion of particles on spherical dimensional spacetimes can, under some assumptions, be described by the curves on a 2-dimensional manifold, the optical and Jacobi mani…
Exotic Compact Objects and the Fate of the Light-Ring Instability
Pedro V. P. Cunha, Carlos Herdeiro, Eugen Radu +1
Ultracompact objects with light-rings (LRs) but without an event horizon could mimic black holes (BHs) in their strong gravity phenomenology. But are such objects dynamically viabl…
