最近的观测发现，几乎覆盖所有太阳表面的太阳针叶都具有很强的磁场。它们应该是从色球发射的等离子体喷流，它们到达了。它们的电子数密度是这样的。相应的等离子体频率(电子质量)几乎等于轴子质量。因此，轴子与质量的共振辐射转换可以在针状体中发生。我们证明了由轴子暗物质转换而来的辐射具有通量密度。辐射随频率呈线状分布。与中子星的类似估计相比，我们的估计在物理参数方面的模糊性更少，因为像电子数密度这样的物理参数在太阳上更明确地被观测到。但是，太强的太阳热辐射将使轴子无法对这种辐射进行敏感的观测。
It has recently been observed that solar spicules covering almost all of solar surface have strong magnetic field. They are supposed to be plasma jets emitted from chromosphere and they arrive up to. Their electron number density is such that. Corresponding plasma frequency(electron mass) is nearly equal to axion mass. Thus, resonant radiation conversion of axion with the mass can arise in the spicules. We show that radiations converted from axion dark matter possess flux density. The radiations show line spectrum with frequency. Our estimation has fewer ambiguities in physical parameters than similar estimation in neutron stars because physical parameters like electron number density have been more unambiguously observed in the sun. But, much strong solar thermal radiations would preclude sensitive observations of such radiations from the axions.
