Conceptual IR Pyramid WFS for Galactic Observations

Explore the potential of Infrared Wavefront Sensor for studying highly obscured regions, galactic center, star-forming regions, and more. An internal meeting was held at Subaru on April 26, 2010, to discuss the feasibility and funding efforts. Learn about the conceptual optical design and key objectives.

Presentation Transcript

  1. Infrared Wavefront Sensor(IR-WFS) Yutaka Hayano Internal Meeting on Future Instrument Projects at Subaru April 26, 2010.

  2. Why IR WFS • Highly obscured region. (No visible guide star.) • Galactic center. • Star forming region. • Disks around massive YSOs • Molecular Gas disks in planet forming disks • Companion search for Class I stars (low mass YSOs) • Jet/Outflow (Class I includes HH objects) • Red objects. (Bright source in IR no in visible.) • M dwarf stars in local group. • Brown dwarf.
