Molecular Lines of CO Isotopes of the High Galactic Latitude Cloud HSVMT27
چکیده انگلیسی
A study on the CO12, CO13, and C18O lines of the high Galactic latitude cloud HSVMT 27, located in Ursa Major, was conducted. A relatively low CO12 excitation temperature was found. While some C18O emissions were detected, they were too weak to be mapped. With the spatial resolution of 0.08 pc and the velocity resolution of 0.17 km·s−1, 26CO13 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.
