毫秒脉冲星计时的多星观测

在评价脉冲星时研究发展趋势的基础上 ,讨论了基于毫秒脉冲星自转的脉冲星时间的短期特征和长期稳定度。并对影响其稳定度的因素作了初步分析。 5 0m射电望远镜计时观测的目的之一就是综合脉冲星时研究。对于 5 0m望远镜计时观测的选星和由多星观测进行综合脉冲星时研究中的数据分析问题进行了讨论。

Timing Multi-millisecond Pulsars by 50 m Radio Telescope

Progress of study on millisecond pulsar time scales was introduced. Some characteristics of millisecond pulsar time scales defined by millisecond pulsar timing observations were discussed. Possible sources which may limit the long term stability of pulsar time scale were analysed. The 50 m radio telescope developed in China will be used for multi-millisecond pulsar timing observation and for study of ensemble millisecond pulsar time scales. A scheme for selection of millisecond pulsars to be monitord regularly by the telescope was given. Principle of timing data analyses in multi-millisecond pulsar observation was discussed.
