Abstract
The Submillimeter Array (SMA) is nearing completion in “millimeter” valley just below the summit of Mauna Kea in Hawaii. Numerous astronomical observations have been undertaken in the partially transparent bands between 0.45 and 1.3 mm. The status of the instrument is described in this paper, and examples of images that have been made with the partially completed Array of the dust and gas envelopes of a high mass protostellar object (IRAS 18089—1732), a low mass young star (LkCa15), and three evolved stars (CRL 2688, V Hydrae, and IRC+10216) are presented.
