论文摘要
我们使用2018年1月至2020年1月之间进行的观测值对过渡性毫秒PSR J1023+ 0038进行了定时分析,高空分辨率光子反质+安装在Asiago的1.82 m copernicus望远镜上。我们报告了完全基于光学数据的定时解决方案的第一个测量和PSR J1023+0038的频率导数。 Pulsar的旋转速率为$(-2.53 \ pm 0.04)\ times 10^{ - 15} $ Hz $^2 $,这是$ \ sim $ 20%慢20%慢20%,比2013 - 2016年的X射线观测值和$ \ sim $ 5%的X射线观测值比在Radio the Reotal Bradive-Pradio-Pradio-fly of the Rotation-power-the Rotation-Power-Power-Power-Power-Power-Power-Power-Power-Power-Power-Power-Power-Power中均固定。
We present a timing analysis of the transitional millisecond pulsar PSR J1023+0038 using observations taken between January 2018 and January 2020 with the high time resolution photon counter Aqueye+ mounted at the 1.82 m Copernicus telescope in Asiago. We report the first measurement of the timing solution and the frequency derivative of PSR J1023+0038 based entirely on optical data. The spin-down rate of the pulsar is $(-2.53 \pm 0.04) \times 10^{-15}$ Hz$^2$, which is $\sim$20% slower than that measured from the X-ray observations taken in 2013-2016 and $\sim$5% faster than that measured in the radio band during the rotation-powered state.
