  1. Prelude to MIRIHerschel: A WISH come true RCW120 Herschel A. Zavagno MIRI NL meeting

  2. The HIFI forest of lines in Orion Bergin et al. 2010

  3. Orion KL

  4. Orion KL - Band 1 Wang et al. 2010

  5. Low-mass protostars: NGC 1333 p-H2O ground-state Line: 1 THz L~20 LSun D~750 lyr outflow Absorption in outer envelope Kristensen, Visser et al. 2010

  6. From low to high mass protostas 105 LSun 430 LSun 20 LSun

  7. Surprise: H2O+ widespread: the fourth ‘phase’ of water W3 IRS5 Benz, Bruderer et al. 2010, in prep.

  8. MIRI GTO program • 450 hr available Europe • 350 hr large programs • High-z galaxies, disks, exoplanets, protostars • 100 hr small programs + reserve • Nearby galaxies, submm galaxies, ISM, GC, AGB stars in external galaxies Large programs factor of 3-4 oversubscribed; small programs < factor of 2 Overheads not yet treated consistently in all cases

  9. z=12 z=5 z=0 Searching for the first stars and galaxies

  10. Protostars HH 212 90’’ HH 211 Near-IR McCaughrean et al. 2002 Tappe et al. 2008

  11. Structure of protoplanetary disks Imaging and spectroscopy as a key tool to reveal disk structure • Probe vertical gas temperature gradients • Coupling of gas and small dust in the “disk atmosphere” (PAHs, VSG) Current understanding strongly driven by Herbig disks [Fedele et al. 2008, Verhoeff et al. 2010]

  12. Disks: uniqueness of MIRI High spectral resolution, high sensitivity, continuous  coverage: • line-to-continuum ratio sufficient to detect minor species • extend studies to faint brown dwarf disks (mJy @ 10m) [Fred Lahuis]

  13. Exoplanet search program

  14. Exoplanetary atmospheres Temperature map of exo-planet Infrared spectra of exo-planets No H2O? Grillmair et al. 2007 Knutson et al. 2007

  15. Procedure and timetable • Draft proposals submitted ~May 20 • Discussed in Marseille among all co-PIs • Feedback (to be) provided to proposers on strengths and weaknesses • Final proposals due August 15 • Co-PIs to make ranking mid-September • Criteria being finalized • Ringberg meeting with US late October • JWST meeting with other instrument teams June 5-8 Grand Tetons

  16. Thanks to everyone for making MIRI into a reality! Stay tuned for FM results in 2011 and science results in 2015….
