标题： Tidal Love numbers of Axion stars

摘要： 我们研究了稳定分支上的球对称轴子星的潮汐可变形性，包括牛顿和相对论分支。 结果表明，在稳定分支上，轴子星的电荷爱因斯坦数为正，而磁荷爱因斯坦数为负。 在牛顿稳定分支上，电荷潮汐爱因斯坦数远大于磁荷潮汐爱因斯坦数，而在相对论稳定分支上，它们稍大一些。 此外，相对论稳定分支的潮汐爱因斯坦数远小于牛顿稳定分支，表明在相对论稳定分支上的轴子星的可变形性较弱。 这可能是由于在相对论分支上，轴子星更加致密，因此几乎不会被潮汐力扭曲。 显示英文摘要

摘要： We investigate the tidal deformability of spherically symmetric axion stars on the stable branches, including the Newtonian and relativistic branches. The results suggest that on the stable branch, the electric Love numbers of axion star are positive, while the magnetic Love numbers are negative. On the Newtonian stable branch, the electric tidal Love numbers are much larger than the magnetic ones, while on the relativistic stable branch, they are slightly larger. Furthermore, the relativistic stable branch has much smaller tidal Love numbers than the Newtonian stable branch, indicating weaker deformability of axion stars on the relativistic stable branch. This could be attributed to the fact that on the relativistic branch, axion stars are more compact, resulting hardly distorted by tidal forces.
