HST proper motion measurements of SNR N132D

We present proper motion measurements of the oxygen-rich ejecta of the LMC supernova remnant N132D using two epochs of Hubble Space Telescope Advanced Camera for Surveys data...我们利用两个观测历元的哈勃空间望远镜（Hubble Space Telescope）巡天高级相机（Advanced Camera for Surveys）观测数据，对大麦哲伦星系（Large Magellanic Cloud，LMC）超新星遗迹N132D的富氧抛射物开展了自行（proper motion）测量。
