CO spectra of two IRAS sources

Abstract

We carried out 12CO J = 1-0 observation on IRAS 05391-0217 and IRAS 06572-0742 using the 13.7-m radio telescope of Purple Mountain Observatory Qinghai Station and obtained the gas parameters. Using IRAS and other infrared data we calculated their dust thermal structure. For the case of T_d < T_k pertaining to IRAS 05391-0217, we considered several possible heating mechanisms and found that photoelectric heating may be an important mechanism while heating by shock wave be a possible one.
