Abstract We present ∼0.″2 (∼80 au) resolution observations of the CO(2–1) and SiO(5–4) lines made with the Atacama large millimeter/submillimeter array toward an extremely young intermediate-mass protostellar source ( t dyn < 1000 yr), MMS 1 located in the Orion Molecular Cloud-3 region. We have...
