标题： HST proper motion confirms the optical detection of PSR B1929+10

摘要： 我们利用2001年采集的一组HST/STIS图像，测量了古老近距脉冲星PSR B1929+10的候选光学对应体自行，此时距离原始FOC探测（Pavlov等，1996）已过去7.2年。 每年位移量μ=107.3±1毫角秒/年，位置角为64.6±0.6°，与最近的VLBA射电测量结果完全一致。 这一结果为PSR B1929+10在光学波段的识别提供了有力确认。 显示英文摘要

摘要： We have measured the proper motion of the candidate optical counterpart of the old, nearby pulsar PSR B1929+10, using a set of HST/STIS images collected in 2001, 7.2 years after the epoch of the original FOC detection (Pavlov et al. 1996). The yearly displacement, mu=107.3+/-1 mas/yr along a position angle of 64.6+/-0.6 deg, is fully consistent with the most recent VLBA radio measurement. This result provides a robust confirmation of the identification of PSR B1929+10 in the optical band.
