摘要A study on ~(12)CO,~(13)CO, and C~(18)O] of the high galactic latitude cloud HSVMT 27, located in Ursa Major, was conducted. A relatively low ~(12)CO excitation temperature was found. While some C~(18)O emissions were detected, they were too weak to be mapped. With the linear resolution of 0.08 pc and the velocity resolution of 0.17 km·s~(-1), 26 ~(13)CO cores were identified in the dense regions. All the local thermodynamic equilibrium masses of these cores are less than their Virial masses, ranging in 0.5-10 M_⊙,and have no infrared point sources associated with them. Overall, the data indicate that there is no recent or ongoing star formation in this cloud.
