毫秒脉冲星的相干去色散偏振测量
Coherently Dedispersed Polarimetry of Millisecond Pulsars
摘要：
我们提出了一个大样本的高精度，相干去色散的毫秒脉冲星（MSP）在410和1414 MHz之间的频率极化配置文件。这些数据包括对几颗双星的第一次偏振观测，以及对其他双星的第一次低频偏振剖面。我们的观察结果支持以前的建议，脉冲形状和偏振的MSP是更复杂的比他们的慢亲戚。一个直接的结论是，偏振为基础的分类计划提出的年轻的恒星只有有限的使用时，适用于毫秒恒星。
英文摘要：
We present a large sample of high-precision, coherently-dedispersed polarization profiles of millisecond pulsars (MSPs) at frequencies between 410 and 1414 MHz. These data include the first polarimetric observations of several of the pulsars, and the first low-frequency polarization profiles for others. Our observations support previous suggestions that the pulse shapes and polarimetry of MSPs are more complex than those of their slower relatives. An immediate conclusion is that polarimetry-based classification schemes proposed for young pulsars are of only limited use when applied to millisecond pulsars.
