论文摘要
可以在太阳芯内大量生产具有大量keV的轴。大多数太阳产生的轴逃到了无穷大，但是一小部分通量是产生的，速度低于逃逸速度。随着时间的流逝，此过程填充了被困在绑定轨道上的缓慢移动轴的盆地。这些轴可以腐烂到两个光子，从而产生可观察的特征。我们使用Nustar X射线望远镜进行的最新静态太阳能观测值对轴的太阳盆地进行了第一个限制。我们比较了设置约束的三种不同方法，并获得了5至30 KEV之间的轴的世界领先限制，在某些情况下，在恒星冷却边界上的提高了耦合的数量级以上。
Axions with masses of order keV can be produced in great abundance within the Solar core. The majority of Sun-produced axions escape to infinity, but a small fraction of the flux is produced with speeds below the escape velocity. Over time, this process populates a basin of slow-moving axions trapped on bound orbits. These axions can decay to two photons, yielding an observable signature. We place the first limits on this solar basin of axions using recent quiescent solar observations made by the NuSTAR X-ray telescope. We compare three different methodologies for setting constraints, and obtain world-leading limits for axions with masses between 5 and 30 keV, in some cases improving on stellar cooling bounds by more than an order of magnitude in coupling.
