To trace the dense gas we used the molecular species NH3, N2H+, HNC, HCO+, H13CO+, HCN and H13CN, where some of them trace the more quiescent gas, while others are sensitive to more dynamical processes. The selected cores have a wide variety of morphological types and also show physical and chemical va","authors_text":"Dario Lorenzetti, Davide Elia, Fabrizio Massi, Francesco Strafella, Jorge L.
