N2H+ depletion in the massive protostellar cluster AFGL 5142
[Aims] We aim at investigating the NH3/N2H+ abundance ratio toward the high-mass star-forming region AFGL 5142 with high angular resolution in order to study whether the NH3/N2H+ ratio behaves similarly to the low-mass case, for which the ratio decreases from starless cores to cores associated with...

| Sumario: | [Aims] We aim at investigating the NH3/N2H+ abundance ratio toward the high-mass star-forming region AFGL 5142 with high angular resolution in order to study whether the NH3/N2H+ ratio behaves similarly to the low-mass case, for which the ratio decreases from starless cores to cores associated with young stellar objects (YSOs). |
