强磁场中的超子星

Hyperon Stars in Strong Magnetic Fields

R. O. Gomes, V. Dexheimer, C. A. Z. Vasconcellos

摘要:

我们研究了强磁场对超子星性质的影响。用一个含参量耦合的强子模型来描述物质。该物质被认为是在零温度,电荷中性,β平衡,包含重子八隅体,电子和μ子。在强磁场(SMF)的存在下,带电粒子的轨道运动是朗道量子化的。两个parametrisations的化学势相关的静态磁场被认为是,达到$1-2 \times 10^{18}\,G$在中心的恒星。最后,通过求解TOV方程,得到了恒星的质量-半径关系和星族分布。

英文摘要:

We investigate the effects of strong magnetic fields on the properties of hyperon stars. The matter is described by a hadronic model with parametric coupling. The matter is considered to be at zero temperature, charge neutral, beta-equilibrated, containing the baryonic octet, electrons and muons. The charged particles have their orbital motions Landau-quantized in the presence of strong magnetic fields (SMF). Two parametrisations of a chemical potential dependent static magnetic field are considered, reaching $1-2 \times 10^{18}\,G$ in the center of the star. Finally, the Tolman-Oppenheimer-Volkov (TOV) equations are solved to obtain the mass-radius relation and population of the stars.
