相对论恒星的阿尔文极振荡
Alfvén Polar Oscillations of Relativistic Stars
摘要：
我们研究了相对论性恒星在强的全球极向偶极子磁场作用下的极阿尔文振荡。在这里，我们只专注于轴对称振荡，研究了数值发展的二维扰动方程。我们的研究表明，极Alfvén振荡的频谱是离散的轴向Alfvén振荡的频谱是连续的。我们还表明，典型的流体模式，如f和p模式，并没有显着的强磁场的存在下的影响。
英文摘要：
We study polar Alfvén oscillations of relativistic stars endowed with a strong global poloidal dipole magnetic field. Here we focus only on the axisymmetric oscillations which are studied by evolving numerically the two-dimensional perturbation equations. Our study shows that the spectrum of the polar Alfvén oscillations is discrete in contrast to the spectrum of axial Alfvén oscillations which is continuous. We also show that the typical fluid modes, such as the f and p modes, are not significantly affected by the presence of the strong magnetic field.
