The Submillimeter Array (SMA) plays a crucial role in studying the warm, dense dust and gas surrounding massive young stars. This paper summarizes recent findings from SMA observations, focusing on deeply embedded protoclusters, the presence of disks around massive stars, bipodal outflows, and the intricate chemistry of "hot core" regions. Advanced continuum and molecular line emission measurements over a 2x2 GHz bandwidth have yielded significant insights into the kinematics and structuring of these celestial phenomena.

LSB X A Massive Star Formation: Recent Results from the Submillimeter Array I. M. Author, CfA, U. R. Author, ASIAA, and SMA Team Abstract The Submillimeter Array (SMA) is an ideal facility to study the warm, dense dust and gas surrounding massive young stars, through (sub)arcsecond resolution observations of continuum and molecular line emission over a 2x2 GHz bandwidth. We will summarize recent results on massive star formation obtained with the SMA. Topics include characterization of deeply embedded protoclusters, evidence for disks around massive young stars, the morphologies and kinematics of energetic bipolar outflows, and the complex chemistry of "hot core" regions.

The Submillimeter Array is a joint project between the Smithsonian Astrophysical Observatory and the Academia Sinica Institute of Astronomy & Astrophysics
