Non-Inhabitable Small planets Key Questions: How do terrestrial planets form? What is the origin of water on the Earth? What is the relationship between small-body belts and terrestrial planet formation? How common are big moons and rings? What are the compositions of extrasolar terrestrial planets? What is the origin of terrestrial planet spins?
Tools: The Rest of the Biomarkers! CO2, CH4, Rayleigh scattering, photosynthetic pigments (visible) CO2, CH4, N2O (IR), sulfur compounds Silicate spectroscopy Find water planets and dry planets. Extended Spectroscopic Capabilities: the bigger the range, the better! Dynamics: Measure eccentricity/inclination/semimajor axis distribution. Orbit Determination Phase Curves: Rings and moons Polarimetry: cloud compositions Correlate planets and exozodiacal clouds.
Giant Planet Key Questions: What creates the range of metallicities in giant planets? Can giant planets form by gas instability? How do giant planets get their eccentricities? What is the role of planet migration? What is the relationship between giant planets and small body belts? What is origin of giant planet spins? Why is there a brown dwarf desert?
Karkoschka 1994 wavelength (nanometers)
Tools: Study RV+SIM Exo-Jupiters Extended Spectroscopic Capabilities: the bigger the range, the better! High Resolution Spectrograph: Transit Observations Follow Up Kepler Discoveries Test mass vs luminosity relations and date systems using SIM Masses
Planets around: A stars, M stars, O+B stars?: more statistics. How does the process of planet formation change with stellar mass? White Dwarfs Much less contrast needed in IR photon noise limited--look in closer (1 AU) than JWST, or more distant objects. Faster photometry---time resolved? What is the future of the solar system? Red Giants: Is is stellar mass loss sudden or adiabatic? Do planets create asymmetries in PN?
Key YSO Questions: Where does the gas go? Do planets open gaps? What is disk temperature and chemistry in the planet-forming region? Do disks become self-shadowed? What forms jets? Find and image new disks. Only 10-20% of sources with IR excess and extended CO emission show disks that HST could see in scattered light. Study disks around brown dwarfs. ALMA takes days to get to 100 zodis!
Study Disk Chemistry Many IR lines not accessible to ALMA. Silicate emission feature 10 microns. H2 emission (IR) 17microns H2O CO CO2 Map dissacociation regions and photoionization regions that generate disk winds that remove the disks. High-resolution IR spectrograph + wide-field imaging. OTHER IDEAS: Resolve closely separated PMS binaries Astrometry of PMS binaries that are too cool or embedded for SIM. IR TPF at 2 microns? Study colimation of jets--X winds? Or disk winds? Very high resolution Optical.
Solar System: Chemistry Comets and in planetary atmospheres: isotopic abundances resolved high-res spectroscopy at Kuiper Belt few x 100 km resolution at Kuiper Belt Hi res IR spectrograph---compare to SOFIA Optical spectroscopy, phase curves, and transit curves of faint objects: KBOs, Comet Cores, NEOs. (few x better resolution than ground-based) Resolve Binary KBOs Follow up LSST and MACHO discoveries.
AGN Key Questions: How do massive black holes form and evolve? What is relationship between galaxies and BHs? IR: Mapping of dusty torii to z=7 detailed kinematics of torii R=2000 Optical: morphology of quasar host galaxies, z=0.2-2 higher contrast and resolutionthan JWST polarimetry of host galaxies: emission physics light echoes gives you distances
Cosmology Key questions: 1) What is Dark Matter? 2) What is Dark Energy? Cluster lensing: Distribution of dark matter Distances: Cepheids (to 3 times farther than HST) Surface brightness fluctuations Measure H0 to 2% = Measurement of w (when combined with WMAP data) Optical: Wide Field of View+Astrometry!
The most distant observed object is lensed through Abell 2218. Objects at z = 5.6 have been found, corresponding to 13.4 billion light years (4.1 Gpc)
