| Abstract: |
A search for dense molecular cloud cores is quite important to investigate the initial conditions of star formation, and, however, has been quite difficult because there are no probes other than high-density gas/dust tracers. Here, we will present the results of our new survey for dense cores in Taurus. We carried out fully sampled ∼3' resolution observations of the 12CO (2–1), 13CO (2–1) and C18O (2–1) emission with the Osaka 1.85-m telescope toward the entire area of the Taurus molecular cloud complex. We found 6 new compact cores in C18O (2–1), with an estimated density of a few ×104 cm–3. They were detected in low-column density (< 3.5 × 1021 cm–2) environment. Their LTE masses are ∼1 M☉, suggesting the possible formation sites of very low-mass stars (or brown dwarfs), and the high spatial observations are highly anticipated. |
