c-C3H2 deuteration towards prestellar and starless cores in the Perseus molecular cloud

Context. In cores deuterium fractionation becomes highly efficient due to low temperatures and CO freeze-out. Cyclopropenylidene (c-C3H2), a small cyclic molecule formed early in chemical evolution, and its deuterated forms serve as valuable tracers of gas-phase deuteration in these environments. Ai...
