论文摘要
轴 - 核子耦合可以通过激发$ {}^{57} \ textrm {fe} $ iSotopes的衰减来产生轴,并且在阳光下通过此过程产生的轴通常是Helioscope搜索的目标。我们首次表明,诸如ZTF J1901+1458之类的热磁白矮人是搜索$ {}^{57} \ textrm {fextrm {fe} $ the Core中的X射线X射线标志的可行目标,然后以核心转换为Magnetosphosphere中的光子。我们计算出,具有Nustar的ZTF J1901+1458的100 kS观察将限制轴与核子和光子的耦合,以低于当前和将来计划的螺旋镜的边界的水平。
The axion-nucleon coupling enables the production of axions through the decay of excited ${}^{57}\textrm{Fe}$ isotopes, and axions produced in the Sun through this process are often a target of helioscope searches. We show for the first time that hot, highly magnetic white dwarfs such as ZTF J1901+1458 are a viable target to search for the X-ray signature of axions that were produced by the ${}^{57}\textrm{Fe}$ transition in the core and then converted to photons in the magnetosphere. We calculate that a 100 ks observation of ZTF J1901+1458 with NuSTAR would constrain the coupling of axions to nucleons and photons at a level below the bounds of both current and future planned helioscopes.
