6. Summary

We presented the results of optical and radio observations and FIR data analysis of the Khavtassi 15 dark cloud. We determined its distance and average visual extinction from the optical measurements, gas mass and density from the radio, and dust properties from the FIR data. The main parameters of the cloud are summarized in Table 7 below.


Table 7. Main parameters of Kh 15

We discussed the relationships between the 13CO (1-0) integrated intensity, FIR emission and extinctions in the optical. We found similar relationships as in the case of the L134 cloud complex. Stability analysis shows that the cloud core is in stable equilibrium. We found the cloud to be most probably connected to a large FIR loop/shell seen around l=126o, b=10o. The wall of the Local Bubble probably lies at a distance of [FORMULA] pc in the direction of Kh 15.
