An evolution of the universe based on a modified time-redshift relation can avoid the introduction of a cosmological constant Astrophys. Space Sci. (IF 1.9) Pub Date : 2024-04-10 Elmo Benedetto, Luca D’Errico, Antonio Feoli
Inspired by the recent literature, we study the Einstein–de Sitter cosmological model coupled with a generalization of the relation between the redshift and time dilation of the kind \(\delta t_{0} = \delta t_{e} (1+z)^{n}\). We find that this model fits the experimental data regarding 1048 supernovae, in a way which is competitive with the standard \(\Lambda \mathrm{CDM}\) model and without the need

Polarization studies in blazars are effective tools for analyzing the emission composition and the relativistic jet. In this work, we collected photometric and polarization data from the Steward Observatory Blazar Monitoring Program and performed the following studies. (1) Among the 10 target sources, 8 sources exhibit correlations between the polarization variability (\(P\)) and \(V\)-lightcurves

Alfvén resonance on Kelvin-Helmholtz vortices at the Earth’s magnetopause Astrophys. Space Sci. (IF 1.9) Pub Date : 2024-04-02
Abstract The Alfvén resonance is an extensively observed phenomenon in astrophysics, playing a crucial role in understanding energy transfer, macroscopic structure, and evolutionary processes within celestial environments such as the magnetospheres of stars, planets, and other astrophysical objects. In this work, we investigate the spatial and temporal distribution of the Alfvén resonance points during

Analysing orbits around the Moon for the Garatéa-L Mission Astrophys. Space Sci. (IF 1.9) Pub Date : 2024-04-02
Abstract Recently, we have seen a series of space missions to the Moon and asteroids, whether for exploratory or scientific purposes, with possibilities of a lot of profitability in a sustainable way. Given this scenario, the Garatéa-L Mission (from the Brazilian original people language Tupi-Guarani, “Search for Life”) stands out, a genuinely Brazilian mission, whose main objective is to place a 6U

Quark stars in the pure pseudo-Wigner phase Astrophys. Space Sci. (IF 1.9) Pub Date : 2024-03-29
Abstract In this paper, we consider the scenario of a pure quark star which is completely composed of quarks in the pseudo-Wigner phase. The equation of state (EoS) of deconfined quark stars is studied in the framework of the two-flavor NJL model, and the self-consistent mean field approximation is employed by introducing a parameter \(\alpha \) combining the original Lagrangian and the Fierz-transformed

An optimal deployment strategy for multi-plane satellite constellation using a generalized non-planar maneuver Astrophys. Space Sci. (IF 1.9) Pub Date : 2024-03-08
Abstract Satellite constellation deployment is a cohesive mission where the trajectories of satellites must be planned concurrently. This paper presents an Integrated Program for Optimal Deployment of a Satellite Constellation (PODSC) consisting of \(m\) non-identical satellites in any desired arrangement in \(n\) orbital planes. The PODSC can optimize the scheduling of mission timelines, ensuring

New class of anisotropic charged strange quark star in Durgapal $IV$ metric and its maximum mass Astrophys. Space Sci. (IF 1.9) Pub Date : 2024-02-05
Abstract In this paper, we have explored the relativistic stellar model considering pressure anisotropy. An anisotropic solution of the Einstein Field Equations (henceforth EFE) has been presented for charged strange quark stars considering the interior space-time geometry described by the Durgapal \(IV^{th}\) metric. In the case of a strange quark star, if the equation of state \(p_{r}=\frac{1}{3}(\rho

Abstract The Swift Gamma-Ray Bursts (GRBs) satellite has observed GRB afterglows with unprecedented resolution over the last two decades, using instruments like the Burst Alert Telescope (BAT), the X-Ray Telescope (XRT), and the Ultra Violet-Optical Telescope (UVOT). This has motivated intensive modeling efforts to interpret these observations, revealing complex light curves with multiple emission

The contribution to the correction of the perihelion precession of binary systems due to energy loss from gravitational radiation emissions, as a follow-up to our previous papers, is obtained for the OJ287 system, which has a large discrepancy not satisfied by the Schwarzschild metric. Using our formulation of the perihelion advance correction from the rate of change of the orbital energy, as well
