Phase-Resolved Ultra-High-Energy Emission Defines an Energetic Boundary for Compact-Object Engines and Dense-Matter Structure

Marlon M. S. Mendes, Cesar H. Lenzi

We show that phase-resolved ultra-high-energy emission from LS I \(+61^\circ303\) defines a critical energetic boundary linking the compact-object engine, circumstellar interaction…

Reconciling GW170817 and GW190814 with a Nonmonotonic Sound-Speed Equation of State

Marlon M. S. Mendes, Odilon Lourenço da Silva Filho, César H. Lenzi

We show that the GW170817-GW190814 tension can be reconciled within General Relativity by a structured causal EoS basin found with a Constrained Evolutionary TOV Discovery pipeline…

Certified Uncertainty for Surrogate Models of Neutron Star Equations of State via Mondrian Conformal Prediction

Marlon M. S. Mendes, Roberta Duarte Pereira, Mariana Dutra da Rosa Louren +1

We present a multitask surrogate for neutron-star equations of state (EoSs) that delivers \emph{distribution-free}, certified uncertainty via split conformal prediction (CP) and it…

-Mode oscillations and the gravitational response of compact stars with analytic equations of state

Kilar Zhang, Alessandro Parisi, C. Vásquez Flores +2

We use a simple holographic model to study the property of cold and dense neutron stars (NSs) and deconfined QCD matter. With the aim of investigating the global properties of comp…

Bayesian approach study of hybrid neutron stars

Fábio Köpp, César H. Lenzi, César V. Flores +1

In this work, we explore how astronomical observations (specifically measurements of masses and radii) can constrain the presence of quark matter inside neutron stars, namely the p…

Examining the influence of anisotropy on the fundamental mode of nonradial oscillation in neutron stars on a complete general relativistic scheme

José D. V. Arbañil, Gabriel O. Cavalheiro, Victor B. T. Alves +3

The anisotropic influence on the -mode frequency of oscillations and dimensionless tidal deformability of neutron stars is analyzed by employing the nonradial oscillation equati…
