Time evolution of o-H${}_2$D${}^{+}$, N${}_2$D${}^{+}$, and N${}_2$H${}^{+}$ during the high-mass star formation process

G. Sabatini, S. Bovino, E. Redaelli +5

Deuterium fractionation is a well-established evolutionary tracer in low-mass star formation, but its applicability to the high-mass regime remains an open question. The abundances…
