论文摘要
最近,在存在强磁场的情况下,在理论上得出了超级脑质量极限,以补充实验观测。在牛顿物理学的框架中,我们通过使用相对论的thomas-fermi方程来研究磁化的白矮人的状态方程,研究了这种磁化白矮人的平衡构型。用于缓慢旋转的恒星的Hartle形式主义已被用来获得平衡方程。在这种形式主义中,已经计算出各种物理量的统一旋转和非旋转的白色矮人。因此,惯性时刻(i),旋转爱情数($λ$)和旋转诱导四极力矩(q)(即i-love-Q关系)之间的普遍关系已被研究为这种磁化的白矮人。 i,偏心率和Q(即i-centricity-q关系)之间的关系也得出了。此外,我们发现,与i-love-Q关系相比,i-centric-q关系更为普遍。
Recently super-Chandrasekhar mass limit has been derived theoretically in presence of strong magnetic field to complement experimental observations. In the framework of Newtonian physics, we have studied the equilibrium configurations of such magnetized white dwarfs by using the relativistic Thomas-Fermi equation of state for magnetized white-dwarfs. Hartle formalism, for slowly rotating stars, has been employed to obtain the equations of equilibrium. Various physical quantities of uniformly rotating and non-rotating white dwarfs have been calculated within this formalism. Consequently, the universality relationship between the moment of inertia(I), rotational love number($λ$) and spin induced quadrupole moment(Q), namely the I-Love-Q relationship, has been investigated for such magnetized white dwarfs. The relationship between I, eccentricity and Q i.e. I-eccentricity-Q relationship has also been derived. Further, we have found that, the I-eccentricity-Q relationship is more universal in comparison to I-Love-Q relationship.
