Spherical Einstein-Friedberg-Lee-Sirlin boson stars: Self-interacting solutions and their astrophysical appearance
Pedro L. Brito de Sá, Haroldo C. D. Lima, Carlos A. R. Herdeiro +1
We investigate boson stars within the framework of the self-interacting Einstein-Friedberg-Lee-Sirlin (E-FLS) model, constituted by a complex scalar field with a quartic self-inter…

Resolving space-time singularities in spherically symmetric black holes: geodesic completeness, curvature scalars, and tidal forces
Haroldo C. D. Lima Junior, Renan B. Magalhães, Gonzalo J. Olmo +1
The existence of black holes in the Universe is nowadays established on the grounds of a blench of astrophysical observations, most notably those of gravitational waves from binary…
