Abstract
We present a study of three small dark clouds in CB130. The Spitzer Space Telescope discovered two young stellar objects in the CB130-1 core. The Spitzer and ground-based telescopes have observed CB130-1 in the infrared and the submillimeter regions. The photometry data from 3.6 micron to 850 micron give us constraints on the radiative transfer modeling. Through the modeling we can figure out the internal luminosity of the young stellar object in CB130-1 core. The more embedded of the two young stellar objects has an internal luminosity, 0.15 L_sun, which is a low value for a young star. We also present the molecular line observation data of the three cores in CB130. Also, we calculate gas temperature of CB130-1 and use an ad hoc step function abundance for Monte Carlo simulation inputs. The step function abundance model fits observed lines reasonably well.
