Tidal Properties of White Dwarfs Admixed with Fermionic Dark Matter
G. A. Carvalho, J. D. V. Arbañil, I. A. Lacerda +1
This study investigates the impact of fermionic dark matter (DM) on the structural and tidal properties of white dwarfs (WDs). Using a two-fluid general relativistic framework, we…
Localized magnetic pressure anisotropy in strange dwarfs with crystalline crusts
Mila Leite Garcia Reis, Daniela Eller Uliana, Jaziel G. Coelho +1
We study equilibrium sequences of magnetized strange dwarfs composed of a self bound MIT bag strange matter core, with \(B_{\rm bag}^{1/4}=145\,{\rm MeV}\), and an ordinary crystal…
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 solvin…
Optical transients from non-explosive double white-dwarf mergers: the case of a central neutron star remnant
M. M. Ridha Fathima, Alexandre M. R. Almeida, Mattia Bulla +3
Discoveries of ultra-massive magnetic white dwarfs (WDs) and peculiar pulsars have been proposed to originate in double white dwarf (DWD) mergers. There are three possible post-mer…
Observational bounds on Dark Matter Admixed Neutron Stars from Gravitational Wave Data
Rafael M. Santos, Rafael C. Nunes, Jaziel G. Coelho +1
Recent gravitational-wave (GW) observations offer a unique opportunity to probe the fundamental nature of compact objects. A growing body of research has focused on exploring the r…
Exploring Temperature Influences on Gravitational Wave Production in Binary White Dwarfs
Sílvia P. Nunes, José D. V. Arbañil, César H. Lenzi +1
This study investigates the conditions under which gravitational waves (GWs) are emitted during the merger of hot white dwarfs (WDs) in a binary system. Traditionally, these system…
