摘要:

在本文中,我们研究了对称斜率对弱磁和强磁中子星可观测性质的影响,采用混沌磁场近似方法。我们通过计算质量、半径、红移、潮汐变形性和基本模式引力波频率,探讨对称能斜率在方程和中子星可观测性质中的影响。我们表明,磁场对低质量星体影响显著,产生更软的方程和相应的较小半径。此外,磁场即使在半径影响较小时,也会导致无量纲潮汐参数显著下降。最后,我们讨论了磁场对中子星通用关系的影响。

英文摘要:

In this work, we study the effect of the symmetry slope on the observables of weakly and strongly magnetized neutron stars within the chaotic magnetic field approximation. We investigate the impact of the symmetry energy slope in the equation of state, as well as on the observables of neutron stars, by calculating their masses, radii, redshifts, tidal deformabilities, and fundamental-mode gravitational-wave frequencies. We show that the effect of the magnetic field is strong on low mass stars, producing a softer equation of state and correspondingly lower values of radii. Furthermore, the magnetic field also causes a significant drop in the dimensionless tidal parameter even when the effects on the radii are small. At the end of the paper, we discuss the effects of the magnetic field in neutron stars' universal relations.
