白矮星双星系统AR Sco的高精度VLBI天体测量研究

摘要

AR Sco，the first radio‐pulsing white dwarf,is an interesting source.Our resulate also show that AR Sco's radio emission compact on milliarcsecondangular scales.With an optimistic attitude,we believe that a better value will be obtainedwhen CC001C data's analysis finished. And the final value will be used to revisitethe related models about AR Sco.
