We investigate the nonrotating neutron stars in $f(T)$ gravity with $f(T)=T+\alpha{T}^2$, where $T$ is torsion scalar teleparallel formalism of gravity. In particular, we utilize SLy and BSk family equations state for perfect fluid to describe stellar matter search effects modification on models stars. For positive $\alpha$, results a smaller mass comparison general relativity, while will conta...
Sudden cardiac death (SCD) is one of the most common modes in Western societies. The exact incidence and etiological background SCD somewhat unknown due to low number autopsies performed sudden victims. In prior autopsy studies approximately 40% victims have other than cause for event countries rates are between 5-25%. Determine Northern Finland. We a certificate review all out hospital or hosp...
Three parameterizations DOPS1, DOPS2, and DOPS3 (named after the Department of Physics Shimla) Relativistic Mean Field (RMF) model have been proposed with inclusion all possible self mixed interactions between scalar-isoscalar (\sigma), vector-isoscalar (\omega) vector-isovector (\rho) mesons up to quartic order. The generated parameter sets are in harmony finite bulk nuclear matter properties....
A precise understanding of the equation state (EOS) dense and hot matter is key to modeling relativistic astrophysical environments, including core-collapse supernovae (CCSNe), protoneutron star (PNSs) evolution, compact binary mergers. In this paper, we extend microscopic zero-temperature BL (Bombaci Logoteta) %nuclear nuclear EOS %derived by Bombaci Logoteta finite temperature arbitrary compo...
Context: Recently, Doroshenko and collaborators reported a very low-mass compact star, Central Compact Object named XMMU J173203.3-344518 inside the supernova remnant HESS J1731-347. Its tiny mass is at odds with all calculations of minimum masses neutron stars generated by iron cores, therefore (and even if not compellingly) it has been suggested to be {\it strange star}. Besides mass, radius ...
Abstract Hyperons are essential constituents in the neutron star interior. The poorly known hyperonic interaction is a source of uncertainty for studying laboratory hypernuclei and observations. In this work, we perform Bayesian inference phenomenological hyperon–nucleon interactions using tidal deformability measurement GW170817 binary merger as detected by LIGO/Virgo mass–radius measurements ...
Abstract The purpose of this paper consists in presenting models compact stars described by a new class exact solutions to the field equations, context general relativity, for fluid configuration which is locally anisotropic pressure. With current sensitivities, we considered non-linear form modified Van der Waals equation state viz., $$p_{r}=\alpha \rho ^{2} +\frac{\beta }{1+\gamma }$$ <mml:ma...
New observational data of neutron stars since GW170817 have helped improve our knowledge about nuclear symmetry energy especially at high densities. We learned particularly: (1) The slope parameter $L$ saturation density $\rho_0$ matter from 24 new analyses is $L\approx 57.7\pm 19$ MeV 68\% confidence level consistent with its fiducial value, (2) curvature $K_{\rm{sym}}$ 16 $K_{\rm{sym}}\approx...
The Magellanic Clouds host a large population of high-mass X-ray binary (HMXB) systems, but although the Large Cloud (LMC) is an order magnitude more massive than Small Cloud, significantly fewer HMXBs are known. We conducted search for new in XMM-Newton observations, which we performed to investigate supernova remnant candidates supergiant shells LMC5 and LMC7. three observed fields located re...
The possible signatures of the presence hyperons inside neutron stars are discussed within a Bayesian inference framework applied to set models based on density dependent relativistic mean field description hadronic matter. Nuclear matter properties, hypernuclei properties and observational information used constraint models. General such as maximum mass, radius, tidal deformability, proton fra...
