Interface Region Imaging Spectrograph (IRIS)
The Interface Region Imaging Spectrograph, or IRIS, mission will use a solar telescope and spectrograph to explore the solar chromospheres. This is a crucial region for understanding energy transport into the solar wind and an archetype for stellar atmospheres. Recent discoveries have shown the chromosphere is significantly more dynamic and structured than previously thought. The unique instrument capabilities, coupled with state of the art 3-D modeling, will explore this dynamic region in detail. The mission will greatly extend the scientific output of existing heliophysics spacecraft that follow the effects of energy release processes from the sun to Earth. Alan M. Title, from Lockheed Martin Advanced Technology Center, Palo Alto, Calif., is the IRIS principal investigator.
Ames will manage mission operations, flight operations and ground systems activities, and provide support for spacecraft systems engineering, flight dynamics, integration and testing. Ames' Multi-Mission Operations Center facility will be used for mission control. Ames also will manage education and public outreach activities.
IRIS is expected to be launched in December 2012.

Using Protoplanetary Disks to Weigh the Youngest Stars and Constrain the Earliest Stages of Stellar Evolution
Abstract: Mass is the fundamental property that determines the fate of a star. In particular, the masses of young stars are of great relevance to many astrophysical problems, including star and planet formation. We have developed a novel approach that combines spatially resolved sub-millimeter spectral line imaging and optical/near-infrared high resolution spectroscopy to derive the fundamental properties of a young star: mass, temperature, and radius. By applying our technique to a sample of pre-main sequence stars, we are mapping out a dynamically-calibrated Hertzsprung-Russell diagram for the express purpose of evaluating pre-main sequence evolutionary models. Looking forward, ALMA is poised to deliver precise stellar masses in statistically large quantities, enabling a meaningful survey of the fundamental properties of young stars.
