CO Core Candidates in the Gemini Molecular Cloud

Abstract

We present observations of a 4 squared degree area toward the Gemini cloud obtained using J = 1-0 transitions of ${}^{12}$CO, ${}^{13}$CO and C${}^{18}$O. No C${}^{18}$O emission was detected. This region is composed of 36 core candidates of ${}^{13}$CO. These core candidates have a characteristic diameter of 0.25 pc, excitation temperatures of 7.9 K, line width of 0.54 km s${}^{-1}$ and a mean mass of 1.4 M$_{\sun}$. They are likely to be starless core candidates, or transient structures, which probably disperse after $\sim$10${}^6$ yr.
