SiO v = 1 J = 5 → 4 Maser Emission from the Root of the “Water Fountain” Source W 43A

SiO v = 1 J = 5 → 4 Maser Emission from the Root of the “Water Fountain” Source W 43A

We report here the first mapping of SiO v = 1 J  = 5 → 4 maser emission toward the “water fountain” source W 43A in order to explore the central stellar system driving the collimated, bipolar, fast jet. The maser source has a systemic line-of-sight velocity consistent with that of CO J  = 2 → 1 emis...
