Three-state active lattice gas: a discrete Vicseklike model with excluded volume
Tiago Venzel Rosembach, Ana Luiza Novaes Dias, Ronald Dickman
We study a discrete-space model of active matter with excluded volume. Particles are restricted to the sites of a triangular lattice, and can assume one of three orientations. Vary…
Spherically symmetric anisotropic strange stars
Luiz L. Lopes, H. C. Das
In this work, we made an extensive study about the possible presence of anisotropies in strange stars. To accomplish this task, we use three different configurations for the strang…
Correlation between the symmetry energy slope and the deconfinement phase transition
Luiz L. Lopes, Debora P. Menezes, Mateus R. Pelicer
We study how the nuclear symmetry energy slope () can affect the hadron-quark phase transition and neutron star properties. We show that the main physical quantities as the crit…
A Bayesian study of quark models in view of recent astrophysical constraints
Franciele M. da Silva, Adamu Issifu, Luiz L. Lopes +2
In this work, we perform a comparative analysis between the density-dependent quark model and the vector MIT bag model using Bayesian analysis. We use the equations of state genera…
Analysis of the dynamics of a spacecraft in the vicinity of an asteroid binary system with equal masses
L. B. T. Santos, P. A. Sousa-Silva, M. O. Terra +8
In this work, we performed a dynamical analysis of a spacecraft around a nearly equal-mass binary near-Earth asteroid with application to the asteroid 2017 YE5, which is also a pos…
One-dimensional random sequential adsorption with one deposition per site
Charles S. do Amaral, Diogo C. dos Santos
We investigate a modified version of the random sequential adsorption model. Specifically, this model involves the deposition of two distinct types of particles onto a lattice…
The VISCACHA survey -- VII. Assembly history of the Magellanic Bridge and SMC Wing from star clusters
R. A. P. Oliveira, F. F. S. Maia, B. Barbuy +15
The formation scenario of the Magellanic Bridge during an encounter between the Large and Small Magellanic Clouds Myr ago, as proposed by -body models, would be impri…
Anisotropic Strange Stars in the Spotlight: Unveiling Constraints through Observational Data
H. C. Das, Luiz L. Lopes
Motivated by the recent suggestions that very massive pulsar (PSR J0952-0607) and very light compact object (HESS J1731-347) exist, in this article, we revisit the possibility of s…
A closer look at the Yukawa's interaction from a symmetry group perspective
Luiz L. Lopes
I investigate the use of the SU(3) Clebsch-Gordan coefficients in light of the relations of completeness and closure. I show that in the case of 1, there is an…
Imprints of the nuclear symmetry energy slope in gravitational wave signals emanating from neutron stars
Luiz L. Lopes, Victor B. T. Alves, César O. V. Flores +1
We investigate possible traces of the nuclear symmetry energy slope () in the gravitational wave emission of neutron stars. For fixed stellar mass values, we examine how the slo…
On the nonlinear electrodynamics in a Lorentz-breaking scenario
E. Neres Júnior, J. C. C. Felipe, A. P. Baêta Scarpelli
In this work, we study a model in nonlinear electrodynamics in the presence of a CPT-even term that violates Lorentz symmetry. The Lorentz-breaking vector, in addition to the usual…
Enlightening the dynamical evolution of Galactic open clusters: an approach using Gaia DR3 and analytical descriptions
M. S. Angelo, J. F. C. Santos, F. F. S. Maia +1
Most stars in our Galaxy form in stellar aggregates, which can become long-lived structures called open clusters (OCs). Along their dynamical evolution, their gradual depletion lea…
SoftED: Metrics for Soft Evaluation of Time Series Event Detection
Rebecca Salles, Janio Lima, Michel Reis +8
Time series event detection methods are evaluated mainly by standard classification metrics that focus solely on detection accuracy. However, inaccuracy in detecting an event can o…
QCD Phase Diagrams via QHD and MIT-Based Models
Carline Biesdorf, Debora P. Menezes, Luiz L. Lopes
In this paper the QCD phase diagram is obtained by the crossing of two effective models: the MIT bag based models are used to describe quark matter and QHD type models to describe…
Glycolaldehyde formation mediated by interstellar amorphous ice: a computational study
Mateus A. M. Paiva, Sergio Pilling, Edgar Mendoza +2
Glycolaldehyde (HOCH2CHO) is the most straightforward sugar detected in the Interstellar Medium (ISM) and participates in the formation pathways of molecules fundamental to life, r…
The full Lorentz-violating vacuum polarization tensor: low and high energy limits
J. C. C. Felipe, A. Yu. Petrov, A. P. Baêta Scarpelli +1
We compute the full vacuum polarization tensor in the fermion sector of Lorentz-violating QED. Even if we assume momentum routing invariance of the Feynman diagrams, it is not poss…
Dark matter effects on hybrid star properties
César H. Lenzi, Mariana Dutra, Odilon Lourenço +2
In the present work we investigate the effects of dark matter (DM) on hybrid star properties. We assume that dark matter is mixed with both hadronic and quark matter and interact w…
Strange Stars within Bosonic and Fermionic Admixed Dark Matter
Luiz L. Lopes, H. C. Das
In this work, we study dark matter (DM) admixed strange quark stars exploring the different possibilities about the nature of the DM and their effects on the macroscopic properties…
