摘要
本文给出红外类星体IRAS 00275—2859的CCD BVRI及近红外JHKL′测光结果.结合IRAS及射电观测资料可发现其能谱与第一个红外类星体IRAS 13349+2438有很大不同且更接近典型类星体的分布,因而有理由认为它在射电、红外和光学波段上的发射主要是非热辐射.由本文观测资料可得其M_B=—23.14,远红外光度L_(IR)=1.58×10^(12)L_⊙,且其远红外光度超出可见光度一个量级.
CCD BVRI and near infrared JHKL' observations of the infrared luminous quasar IRAS 00275—2859 are presented in this paper. Combined with the data from IRAS and radio bands, it is found out that it's energy distribution is different from the one of the first infrared quasar IRAS 13349 + 2438, but close to that of typical quasars. It is reasonable to consider that the radiation from IRAS 00275—2859 in radio, infrared and optical regions is mostly nonthermal. In addition, we get M_B=—23.14, far infrared luminosity L_(IR)=1.58×10^(12)L_⊙ and L_(IR)/L_B≌10 for IRAS 00275—2859.
