Considerations on the Origin of IRAS 19312+1950 Based on Long-Term Maser Observations

Huan-Xue Feng, Jun-ichi Nakashima, D. Engels +5

IRAS source 19312+1950 (hereafter I19312) is an infrared point source with maser emissions of SiO, HO, and OH molecules. Although initial observations suggested that I19312 mig…
