Surprise: H 2 O + widespread: the fourth ‘phase’ of water Benz, Bruderer et al. 2010, in prep. W3 IRS5
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
Searching for the first stars and galaxies z=12 z=5 z=0
10
Protostars HH 212 HH 211 Tappe et al. 2008 90’’ Near-IR McCaughrean et al. 2002
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 Grillmair et al. 2007 Knutson et al. 2007 No H 2 O?
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….
