Fornax dSph star members study with GaiaEDR3

We have studied the extent of the Red Giant Branch stellar population in the Fornax dwarf spheroidal galaxy using the spatially extended and homogeneous data set from Gaia EDR3....我们利用盖亚卫星第三批早期数据发布（Gaia EDR3）提供的空间延展且均匀的数据集，对天炉座矮球状星系（Fornax dwarf spheroidal galaxy）内红巨星支（Red Giant Branch）恒星族群的分布范围开展了研究。
