  1. The Mid-infrared on ELT’s (3 – 25µm) MIR recommended to be essential

  2. R~300

  3. Present MIR instruments: <8m

  4. Present MIR instruments: ≥8m 4 Sensitivity = BLIP x Site x Telescope

  5. A taste of spatial resolution 4m viz 8m AGNvizstarburst unresolved resolved

  6. HR spectroscopy: velocity field Keplerian gas motion-> black hole mass NGC 7582 NeII (12.8µm) Wold et al. 2006 VLT,JWST, … - ≤ 10m - unresolved ELT - > 30m - resolved

  7. flux [ mJy] Spitzer VISIR METIS

  8. MIR/ELT `galactic’ science cases • Life cycle of dust • Star formation • Governing disk architecture for planet formation • Dynamical history of the solar system • …. MIR/ELT will solve host of astronomical questions by resolved spectroscopy and imaging

  9. Formation of stars in MC Evolution of proto-planetary & debris disks Planetformation Solar system: unique? Building blocks & Origin of life

  10. Richness of MIR +extinction Molecules: ~13µm + solid state + PAH + atoms + ions

  11. MIR spectroscopy in: ISM, disks, comets Resolved lines -> velocity information; density, temperature, abundance Single exposure (not with ALMA) Photoevoparative disk wind TW Hya [NeII] flux N2O j ≤ 46 transitions Pascuci&Sterzik’09 wavelength (nm) v [km/s]

  12. Proto-planetary disks - chemical structure of the disk - velocity field and turbulent disk mixing - probe pathways of planet formation scale: --- ELT ---> <---- ALMA ---

  13. Exo-planets - Ground: RV studies + scattered light imaging -> Orbit parameters (M, r, ε) Transit~> atmosphere • Space: Kepler, SIM • improved statistics • ELT/MIR: • Resolving disk structure • Velocity field • Planet thermal emission • Spectroscopy of bio markers

  14. Origin of life ? In-situ search for prebiotic molecules Delivery to Earth via heavy bombardment? -> ELT provide event Statistics of: 3-5µm: ices in comets (Mumma et al.)

  15. Debris disk structure: theory JWST 30m Disk + planet: possible dust density (Ozernoy et al.) 20µm dust emission at 40pc (Wilner et al)

  16. Debris disks with planet: beta Pic Lagrange et al. 3.6µm Telesco et al. 8-25µm ELT -> Statistics on the debris disk structure

  17. Thermal emission of a planet Pantin et al. ‘08
