太阳轴子的X射线探测

X-Ray Searches for Solar Axions

Hugh S. Hudson, L. W. Acton, E. DeLuca, I. G. Hannah, K. Reardon, K. Van Bibber

摘要:

太阳核心中热产生的轴子在穿过太阳大气层时通过与磁场的相互作用几乎可以直接转换为X射线。这个转换过程的结果将是在圆盘中心的几keV X射线的扩散中心集中源;它将具有已知的尺寸,大约是太阳直径的10%,并且光谱分布类似于太阳核心的黑体光谱。其空间结构的细节将取决于太阳大气中的质量和场的分布。源的亮度取决于这些因素以及未知的耦合常数和未知的轴子质量;这种粒子是假设的,尚未发现其存在的确凿证据。我们将太阳磁场环境描述为一个轴子/光子转换器,并讨论了三个太阳X射线观测站(Yohkoh,RHESSI和Hinode)现有和专用观测所获得的上限

英文摘要:

Axions generated thermally in the solar core can convert nearly directly to X-rays as they pass through the solar atmosphere via interaction with the magnetic field. The result of this conversion process would be a diffuse centrally-concentrated source of few-keV X-rays at disk center; it would have a known dimension, of order 10% of the solar diameter, and a spectral distribution resembling the blackbody spectrum of the solar core. Its spatial structure in detail would depend on the distribution of mass and field in the solar atmosphere. The brightness of the source depends upon these factors as well as the unknown coupling constant and the unknown mass of the axion; this particle is hypothetical and no firm evidence for its existence has been found yet. We describe the solar magnetic environment as an axion/photon converter and discuss the upper limits obtained by existing and dedicated observations from three solar X-ray observatories: Yohkoh, RHESSI, and Hinode
