WISE YSO candidates near {sigma} and {lambda} Ori

We have conducted a sensitive search down to the hydrogen burning limit for unextincted stars over ~200 square degrees around Lambda Orionis and 20 square degrees around Sigma...我们针对猎户座λ（Lambda Orionis）周围约200平方度、以及Sigma周围约20平方度的天区内的未消光恒星，开展了灵敏度下限达到氢燃烧极限（hydrogen burning limit）的巡天搜索。
