  1. Spatially resolved, high resolution IR spectroscopy of disks around young stars An ELT feasibility study by: Gerrit van der Plas Science day, Oct 13th 2006

  2. In perspective.. • Old star (and planet) forming paradigm. • At the moment, a lot of good work is done. However, mainly indirect evidence. • The new era of ELT's will help

  3. ‘Isolated’ Star Formation M.Hogerheijde1998, after Shu et al. 1987

  4. A possible ELT observing proposal • Old star (and planet) forming paradigm. • At the moment, a lot of good work is done. However mainly indirect evidence. • The new era of ELT's will help.

  5. Proposed observations: (evolution of) circumstellar disks Left: Mayer et al.(2004) Right: Kurosawa & Harries • Solve spatially • Extremely high spectral resolution.

  6. Is BIG big enough?? In astronomy, bigger = better! ! Assume a 50M mirror: • 1 µm -> ~ 4 mas • 5 µm -> ~ 20 mas • 10 µm -> ~ 40 mas • 20 µm -> ~ 80 mas • -> ~AU imaging out to 10 µm in TW Hya and 3-4 µm in ρ Oph • Volume accessible scales to the diameter as D3 , S/N as D4!
