天体物理中存在磁场时相对论Rankine-Hugoniot条件的求解

Solving the relativistic rankine-hugoniot condition in presence of magnetic field in astrophysical scenario

Ritam Mallick

摘要:

Rankine-Hugoniot条件是研究天体物理中相变的一个重要条件,主要是研究从中子星(NS)到夸克星(QS)的相变。相变是由燃烧前沿引起的,该燃烧前沿从中心行进到表面。状态方程和温度方程在决定导致中子星相变的波前传播的性质方面起着巨大的作用。引入了磁场,得到了修正的垂直激波和斜激波守恒条件。垂直激波的数值解如图所示,发现磁场有助于激波的产生。它间接地暗示了物质的不稳定性,从而暗示了NS对于非常高的磁场的不稳定性,这意味着NS只能支持有限的磁场强度。

英文摘要:

Rankine-Hugoniot condition has been solved to study phase transition in astrophysical scenario mainly in the case of phase transition from neutron star (NS) to quark star (QS). The phase transition is brought about by a combustion front, which travels from the center to the surface. The equations of state and temperature plays a huge role in determining the nature of the front propagation, which brings about the phase transition in neutron stars (NSs). Magnetic field has been introduced and the modified conservation condition for the perpendicular and oblique shocks is obtained. Numerical solution of the perpendicular shock has been shown in the figures, which finds that the magnetic field helps in shock generation. It indirectly hints at the instability of the matter and thereby the NS for very high magnetic field, implying that NSs can only support finite magnetic field strength.
