  1. Towards the science case for E-ELT HIRES – Cambridge, Sept 13-14, 2012 E-ELT HIRES SCIENCE CASES: STELLAR SPECTROSCOPY and YOUNG STARS optical+near IR high res stellar spectroscopy 8-10m class telescopes massive stars, luminous giants/SGs in the Galaxy & LG PMS E-ELT low luminosity stars in the Galaxy luminous stars in the LG and beyond Livia Origlia – INAF Bologna, Italy

  2. Towards the science case for E-ELT HIRES – Cambridge, Sept 13-14, 2012 E-ELT HIRES SCIENCE CASES: STELLAR SPECTROSCOPY and YOUNG STARS optical + near IR high res stellar spectroscopy @ E-ELT stellar populations (Tolstoy & de Laverny talks) chemical evolution & stellar archaeology stellar physics, evolution & nucleosynthesis young stars (Testi/Nisini) proto-star & star-disk interaction  planet formation distant star clusters (Larsen talk) chemical composition & dynamical mass constraints on the IMF & the host galaxy Livia Origlia – INAF Bologna, Italy

  3. Towards the science case for E-ELT HIRES – Cambridge, Sept 13-14, 2012 E-ELT HIRES SCIENCE CASES: STELLAR SPECTROSCOPY and YOUNG STARS optical + near IR high res stellar spectroscopy @ E-ELT very high s/n … very precise chemical abundances (Gustafsson & Korn talk) very precise stellar parameters (Ammler-von Eiff, Tautenburg) isotopic abundances (Israelian talk + 12C18O,12C17O 2.349-2.352 mm R>=100k) granulation in stars with transiting planets (Dravins – Lund) = - high resolution line profiles across spatially resolved stellar disks! asteroseismology in M dwarfs (Gonzalez & Rodriguez-Lopez - Granada) pulsations will help determining the frontier between partially- and fully-convective structure in M dwarfs (SpT M3.5 ?) Livia Origlia – INAF Bologna, Italy
