Abstract天体测量法是探测系外行星一种有效的手段,具有其他探测方法所不具备的独特优势,如可以探测到行星的3维轨道参数及确定行星的质量等,这些将为现有的行星样本提供重要补充.高精度的空间天体测量卫星Gaia(Global Astrometric Interferometer for Astrophysics)在2013年成功发射升空,可以预期未来基于其探测数据,将可能发现大量的长周期类木行星.针对αCentauri A、HD 62509和GJ 876系统,根据Gaia单次天体测量精度生成对应的仿真数据,使用Lomb-Scargle周期谱分析行星轨道周期信号,并采用Markov Chain Monte Ca...
