Ultra-High-Energy Particle Production in Binary Mergers Endowed with Magnetic Fields
Carlos H. Coimbra-Araujo, Rita C. Anjos, Jonas P. Pereira +1
We study the production of ultra-high-energy particles via the Bañados--Silk--West (BSW) mechanism in the pre-merger phase of binary systems detected by LIGO-Virgo-KAGRA. By solvi…

Constraints on QCD-based equation of state of quark stars from neutron star maximum mass, radius, and tidal deformability observations
João V. Zastrow, Jonas P. Pereira, Rafael C. R. de Lima +1
(Abridged) Neutron stars (NSs), the densest known objects composed of matter, provide a unique laboratory to probe whether strange quark matter is the true ground state of matter.…

Impact of stratified rotation on the moment of inertia of neutron stars
Jonas P. Pereira, Tulio Ottoni, Jaziel G. Coelho +2
Rigid (Uniform) rotation is usually assumed when investigating the properties of mature neutron stars (NSs). Although it simplifies their description, it is an assumption because w…
