  6. METIS Instrument Baseline • Imaging at 3 – 19 μm. with low/medium resolution slit spectroscopy as well as coronagraphy for high contrast imaging. • High resolution (R ~ 100,000) IFU spectroscopy at 3 – 5 μm, including extended instantaneous wavelength coverage. • Work at the diffraction limit with single conjugate (SC) and eventually assisted by a laser tomography adaptive optics (LTAO) system.

  12. (Multiple) Planet Forming Disks: HD 100546 Not yet detected in K-band (Quanz et al. 2013; 2015b)and there are other examples…

  13. Direct Detection (and Characterization) of Circumplanetary Disks Quanz et al. (2015b); METIS/HARMONI/MICADO Science

  14. Direct Detection of Thermal Emission for Planets of Known Mass with E-ELT: Calibrating the Models RV+Gaia follow-up requires imaging photometry and IFU spectroscopy! Quanz et al. (2015a); METIS/MICADO/HARMONI Science

  15. Phenomenological Planet Populations: RV Data GI CA Benz et al. (2014); Galvagni & Mayer (2014); Forgan & Rice (2013)

  16. Direct (Non-) Detections of Gas Giant Planets Few massive planets at large orbital radii. [>3 Mjup @ > 50 AU] dN/da ~ ab NACO-LP: Chauvin et al. (2014) Not good for GI Lafrenerie et al.

  17. DIRECT IMAGING: DISRUPTING PLANET FORMATION THEORY WITH THE E-ELT • Start with a fit to RV distributions (Cumming et al. 2008) with brown dwarf companions (Reggiani et al. submitted) • Evidence for dependence of Co, planet frequency over range of mass and orbital radius, on stellar mass (Johnson et al. 2010; Clanton et al. 2014). • Initial conditions (and theory) suggest dependence on ratio of planet mass to star mass. • RV/micro-lensing/Imaging consistent with log-normal surface density peaking at 10 AU (Meyer et al. in prep).

  19. High Resolution Spectra of Brown Dwarfs and Planets:METIS/HARMONI Characterization Science Brown dwarf doppler imaging with CRIRES Wind speeds on planets with CRIRES Crossfield et al. (2014) Snellen et al. (2014)

  20. Star Clusters, Disks, & Planets: E-ELT Opportunities SYNERGIES => Building on legacy of VLT: E-ELT, JWST, and ALMA. => METIS and first-light instruments HARMONI & MICADO. STAR CLUSTERS => Resolved IMFs within 10 Mpc. DISKS => E-ELT will resolve planet-forming disks (gas and dust) inside 10 AU. => Spectro-astrometry: of what are forming planets in disks made? => E-ELT will detect planets in formation (and circumplanetary disks). PLANETS => Direct detection of planets with known mass (constrain models). => Collide planet formation theory with planet populations vs. stellar mass. => Characterize gas giant planets, including phase maps, and weather! => Possible to image (and characterize) a handful of super-earths.

  26. CA Phenomenology: Planet Masses and Orbits Solid growth time: tp ~ Rprp / [ Sd x d] with Sd~ M*/a and d~ sqrt(M*/a3) tp ~ a5/2/ [M*3/2] cf. gas disk lifetime td ~ 1/M* Given aouter, there is a timescale td ~ 1/M* giving Rp. aouter ~ [td M*3/2]2/5 ~ M*1/5 Very hard to form critical mass core beyond 10s of AU (all stars). If Mp set by disk accretion: Mp ~ [dMacc/dt ] td ~ M*2 x (1/M*) ~ M* Planet Mass linearly related to star mass.

  27. GI Phenomenology: Planet Masses and Orbits Toomre Parameter: Q ~ cs(a) W/ GS(a) with Sd ~ M*/a, d~ sqrt(M*/a3), and cs ~ sqrt(T) ~ (M*/a)1/4 Q ~ 1/ [M*1/4 a3/4] Depends “weakly” on stellar mass, more strongly on radius. For typical disk parameters, should operate > 50 AU. Typical fragment mass would be ~ cs4/S(a) ~ 5 Mjupiter. Massive planets, beyond 50 AU, independent of stellar mass.
