The Gemini NICI Planet-Finding Campaign
• Three-year campaign @ Gemini-South 8.1-m Telescope for direct imaging of exoplanets: ~500 queue hrs, ~300 stars.
• Campaign science questions:
• Started in Dec 2008, completion in late-2011/early-2012.
1. What is the frequency of gas-giant planets at > 5-10 AU?
2. How does planet frequency depend on stellar mass?3. What do the SEDs of young planets look like?
NICI = Dedicated exoplanet imagerCH4 short (1.58 m) CH4 long (1.65 m)
1. High-order NGS AO: UH 85-elem curvature system
2. Spectral Difference Imaging (SDI)3. Roll subtraction (a.k.a. ADI = angular difference imaging)
