BL Lac天体表现出一系列特殊的观测性质.按照巡天方式可以分为X-选择和射电选择BL Lac天体.很多人讨论了这两者之间的关系.文章的主要工作是:①选取了两个样本;②收集了最高观测偏振读,寄主星系的绝对星等、核主导系数等;③计算了热光度、同步辐射峰频以及峰频所对应的光度、有效谱指数.基于这些数据,考察了两类BL Lac天体的性质.结果表明:X-选择和射电选择BL Lac天体在热光度、核主导系数以及有效谱指教等性质是不同的,但它们具有很相似的同步峰频光度.

BL Lacertae objects show some particularly observational properties. They were classified as radio-selected and X-ray selected BL Lacertae objects from surveys. Many authors have investigated maximum optical polarization, absolute magnitude of the host galaxy, and core-dominance parameter,cy, and the effective spectral indexes for some objects. Based on those data, we revisited the properties of BL Lacertae objects. The results show that radio-selected and X-ray selected BL Lacertae objects are different in the bolometric luminosity, the core-dominance parameters, and the effective spectral indexes, but they have similar peak-frequency luminosity.
