论文摘要
旋转的中子恒星或脉冲星可能是伪Nambu Goldstone玻色子或轴的可能来源，可以介导脉冲星外的远距离轴心发。当电磁辐射从脉冲星发射并穿过远距离轴心头发时，轴旋转电磁辐射的极化并产生双重双重。由于这种长距离头发为$ 0.42^\ circ $，我们获得了双向弗林格的角度。该结果独立于旋转频率，脉冲星的半径，轴心的质量和轴突光子耦合常数。该值在测量$ \ leq 1.0^\ Circ $的Pulsar Light的线性极化角度范围内。只要轴突头发的范围（轴支质量）大于脉冲星的半径，即，我们的结果就会继续保持。 $ m_a <10^{ - 11} $ eV和轴衰减常数$ f_a \ sillesim \ mathcal {o}（10^{17} \ rm {gev}）$。
Rotating neutron star or pulsar can be a possible source of pseudo Nambu Goldstone bosons or axions which can mediate long range axionic hair outside of the pulsar. When the electromagnetic radiation is emitted from pulsar and passes through the long range axion hair, the axion rotates the polarization of the electromagnetic radiation and produces birefringence. We obtain the angle of birefringence due to this long range axionic hair as $0.42^\circ$. This result is independent of the rotational frequency, radius of the pulsar, mass of the axion, and axion photon coupling constant. This value is within the accuracy of measuring the linear polarization angle of pulsar light which is $\leq 1.0^\circ$. Our result continues to hold as long as the range of the axion hair (inverse of axion mass) is greater than the radius of the pulsar, i.e; $m_a<10^{-11}$eV and the axion decay constant $f_a\lesssim \mathcal{O}(10^{17}\rm{GeV})$.
