论文摘要
我们报告了从超磁性中子星线与成像X射线极化探索器（IXPE）的线性极化X射线发射的首次检测。 IXPE 35观察到异常的X射线脉冲星4U 0142+61揭示了整个IXPE 2--8 KEV频段的线性极化度为$（12 \ pm 1）\％$。我们检测到具有能量的极化的实质性变化：该度为$（14 \ pm 1）\％$在2--4 keV和$（41 \ pm 7）\％$ $ $ $ $ $ $ $ $ $ $ $在5.5---8 keV中，而它下降到4--5 kev的器乐敏感性以下，在4--5 keV左右，极性角度摆动$ \ sim 90^cirp $ \ sim 90^\ $ $ $。 IXPE观察结果为我们提供了有关中子星表面和磁层的特性的全新信息，并为真空双折射的量子机械效应的存在提供了进一步的支持。
We report on the first detection of linearly polarized x-ray emission from an ultra-magnetized neutron star with the Imaging X-ray Polarimetry Explorer (IXPE). The IXPE 35 observations of the anomalous x-ray pulsar 4U 0142+61 reveal a linear polarization degree of $(12\pm 1)\%$ throughout the IXPE 2--8 keV band. We detect a substantial variation of the polarization with energy: the degree is $(14\pm 1)\%$ at 2--4 keV and $(41\pm 7)\%$ at 5.5--8 keV, while it drops below the instrumental sensitivity around 4--5 keV, where the polarization angle swings by $\sim 90^\circ$. The IXPE observations give us completely new information about the properties of the neutron star surface and magnetosphere and lend further support to the presence of the quantum mechanical effect of vacuum birefringence.
