PROPER MOTION OF PULSAR B1800-21

摘要

We report high angular resolution, multiepoch radio observations of the young pulsar PSR B1800—21. Using two pairs of data sets, each pair spanning approximately a 10 year period, we calculate the proper motion of the pulsar. We obtain a proper motion of μ_α = 11.6 ± 1.8 mas yr~(-1), μ_δ = 14.8 ± 2.3 mas yr~(-1), which clearly indicates a birth position at the extreme edge of the W30 supernova remnant. Although this does not definitively rule out an association of W30 and PSR B1800—21, it does not support an association.
