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…
Quasistationary solutions of scalar fields around collapsing self-interacting boson stars
Alejandro Escorihuela-Tomàs, Nicolas Sanchis-Gual, Juan Carlos Degollado +1
There is increasing numerical evidence that scalar fields can form long-lived quasi-bound states around black holes. Recent perturbative and numerical relativity calculations have…
Numerical evolutions of spherical Proca stars
Nicolas Sanchis-Gual, Carlos Herdeiro, Eugen Radu +2
Vector boson stars, or , have been recently obtained as fully non-linear numerical solutions of the Einstein-(complex)-Proca system. These are self-gravitatin…
Completion of the universal I-Love-Q relations in compact stars including the mass
Borja Reina, Nicolas Sanchis-Gual, Raül Vera +1
In a recent paper we applied a rigorous perturbed matching framework to show the amendment of the mass of rotating stars in Hartle's model. Here, we apply this framework to the tid…
