The SMA is a very powerful tool to study star and planet forming regions and a variety of observational projects have been carried out in ASIAA. For instance, the well-known HH211 outflow emerging from a nearby young star was imaged in detail using the SMA. The SMA images show a very narrow jet-like structure in the outflow, and the SiO jet consists of a chain of knots separated by 3-4" (~1000 AU), with most of them having counterparts in shocked H2. |
