论文摘要
我们介绍了500米孔球形射电望远镜（快速）发现的11个脉冲星的定时解决方案和分析。这些脉冲星是在快速调试阶段进行的漂移扫描观测中使用超宽带宽接收器发现的，然后使用64-m Parkes射程望远镜确认并定时。在至少一年的时间内观察到了每个脉冲星。突出显示的发现包括PSR J0344-0901，该发现显示模式改变的行为，可能属于所谓的“ swooshing”脉冲星（与PSRS B0919+06+06和B1859+07一起）的类别； PSR J0803-0942，其发射几乎完全线性极化； PSRS J1900-0134和J1945+1211，其定义良好的极化角曲线对其发射几何形状进行了严格的约束。我们通过早期的调查进一步讨论了这些脉冲星的可检测性，并从我们的工作中汲取了教训，从我们的工作中进行了确认和监测高度敏感望远镜发现的脉冲星的观察结果，其中许多可能适用于下一代脉冲案调查。本文标志着快速发现的脉冲星的第一个主要版本之一，并为未来发现的未来发现的途径铺平了循环。
We present timing solutions and analyses of 11 pulsars discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST). These pulsars were discovered using an ultra-wide bandwidth receiver in drift-scan observations made during the commissioning phase of FAST, and were then confirmed and timed using the 64-m Parkes Radio Telescope. Each pulsar has been observed over a span of at least one year. Highlighted discoveries include PSR J0344-0901, which displays mode-changing behaviour and may belong to the class of so-called `swooshing' pulsars (alongside PSRs B0919+06 and B1859+07); PSR J0803-0942, whose emission is almost completely linearly polarised; and PSRs J1900-0134 and J1945+1211, whose well defined polarisation angle curves place stringent constraints on their emission geometry. We further discuss the detectability of these pulsars by earlier surveys, and highlight lessons learned from our work in carrying out confirmation and monitoring observations of pulsars discovered by a highly sensitive telescope, many of which may be applicable to next-generation pulsar surveys. This paper marks one of the first major releases of FAST-discovered pulsars, and paves the way for future discoveries anticipated from the Commensal Radio Astronomy FAST Survey (CRAFTS).
