摘要
本课题的研究目的是利用R(红)-l(近红外)两色照相测光方法,搜寻银道带天区的红外超天体,并证认IRAS点源的近红外光学对应体。本文是一组文章的第二篇。在天坛天区发现了225个红外超天体,并证认出其中27个为IRAS点源的对应体。
With the purpose of searching for infrared-excess objects near the galactic plane, a star-field of 28.5 square degrees in Ara direction has been measured on UK Schmidt plates R4365 and 14364 with the Cosmos machine at Royal Observatory, Edinburgh. The defined criterion of infrared-excess objects and the technique used for searching infrared stellar objects were described in the paper [2] . Star counting and data reduction of the photographic R-I photometry were carried out with the VAX 11/780. Two hundred and twenty five infrared-excess objects with colour index R-I ≥ 2.5 in this field are discovered. In these red stellar objects, 27 have been identified as optical counterparts of the IRAS point sources.
