摘要
对所收集的BL Lac天体的红外资料(Fan&Lin 1999)进行讨论,发现具有红移的27个BL Lac天体的红外谱指数与红移之间有强相关,这种强相关也许意味着谱存在演化效应.
Abstract
In this paper, based on the historical infrared (JHK) data compiled by Fan & Lin ( 1999)[1], the color index properties are discussed for 27 radio selected BL Lacertae objects (RBLs). A strong correlation is found between color indices and redshift, which probably suggests an effect of evolution.
