Lensing and dynamics of ultra-compact bosonic stars
Pedro V. P. Cunha, José A. Font, Carlos Herdeiro +3
Spherically symmetric bosonic stars are one of the few examples of gravitating solitons that are known to form dynamically, via a classical process of (incomplete) gravitational co…
Light ring stability in ultra-compact objects
Pedro V. P. Cunha, Emanuele Berti, Carlos A. R. Herdeiro
We prove the following theorem: axisymmetric, stationary solutions of the Einstein field equations formed from classical gravitational collapse of matter obeying the null energy co…
Fundamental photon orbits: black hole shadows and spacetime instabilities
Pedro V. P. Cunha, Carlos A. R. Herdeiro, Eugen Radu
The standard Black Holes (BHs) in General Relativity, as well as other ultra-compact objects (with or without an event horizon) admit planar circular photon orbits. These light rin…
