A study of the $c$-${\mathrm{C}}_3\mathrm{HD}$/$c$-${\mathrm{C}}_3{\mathrm{H}}_2$ ratio in low-mass star forming regions

J. Chantzos, S. Spezzano, P. Caselli +4

We use the deuteration of $c$-${\mathrm{C}}_3{\mathrm{H}}_2$ to probe the physical parameters of starless and protostellar cores, related to their evolutionary states, and compare it to the…
