The Extraordinary Outburst in the Massive Protostellar System NGC 6334 I-MM1: Spatiokinematics of Water Masers during a Contemporaneous Flare Event

Following an eruptive accretion event in NGC 6334I-MM1, flares the various maser species, including water masers, were triggered. We report observed relative proper motion of highly variable masers associated with massive star-forming region, 6334I. High velocity H2O motions detected five clusters, CM2-W2 (bow-shock structure), MM1-W1, MM1-W3, UCHII-W1, and UCHII-W3. The overall average derived is 85 km s−1. This mean agreement previous results from VLA multiepoch observations. Our position as well variance covariance matrix analyses show its major axis to have a angle −794, cutting through dust cavity around MM1B being aligned northwest–southeast direction. interpret this jet driving CM2 shock motion. complicated MM1-W1 can be explained by combined influence MM1 northeast–southwest bipolar outflow, CS(6−5) north–south collimated radio jet. UCHII-W1 are likely not driven jets protostar but MM3-UCHII. Overall, post-accretion burst trace shocks
