Abstract: Molecular hydrogen emission has been detected everywhere in the central parsec of the Galaxy, where the ionization coming from the young stars would nominally destroy it. The presence of the molecular gas in this extreme environment remains therefore unexplained. Here, we present observations of resolved layers of molecular and ionized gas around the massive young star GCIRS 16C, obtained with the integral field unit OSIRIS at the Keck Observatory. This is an exemplary case to test whether the molecular gas could form and survive in the cooling, outflowing wind of evolved stars.
