Observing Massive Stars with ALMA

Diah Setia Gunawan (Atacama Large Millimeter/Submillimeter Array ALMA)

The Atacama Large Millimeter/submillimeter Array (ALMA) is entering its Early Science Cycle 0 phase and will be working with its full capabilities in 2012. In this talk, we will explore the possibilities to exploit the strength of ALMA: its frequency coverage, wide bandwidth, spectral/continuum sensitivity, angular and spectral resolution for solving current issues in massive star studies. Some of the vexing issues in the observational aspect in massive star studies will be discussed. Among these are: clumping and mass loss in massive stars; dust formation in massive binaries: geometry and mechanism; magnetic field; multiplicity and massive stars formation. We will attempt to recognize what we can obtain with ALMA and project future studies.
