Slowly Rotating Anisotropic Neutron Stars in General Relativity and Scalar-Tensor Theory
Hector O. Silva, Caio F. B. Macedo, Emanuele Berti +1
Some models (such as the Skyrme model, a low-energy effective field theory for QCD) suggest that the high-density matter prevailing in neutron star interiors may be significantly a…
Absorption of planar massless scalar waves by Bardeen regular black holes
Caio F. B. Macedo, Luís C. B. Crispino
Accretion of fields by black holes is a subject of great interest in physics. It is known that accretion plays a fundamental role in active galactic nuclei and in the evolution of…
Light rings as observational evidence for event horizons: long-lived modes, ergoregions and nonlinear instabilities of ultracompact objects
Vitor Cardoso, Luis C. B. Crispino, Caio F. B. Macedo +2
Ultracompact objects are self-gravitating systems with a light ring. It was recently suggested that fluctuations in the background of these objects are extremely long-lived and mig…
