  1. Roger Hunter (Ames Research Center) & Kepler Team March 26, 2010

  2. Life on HAT-P-7b? HAT-P-7: Distance: 320 pc Magnitude: 10.5 Mass: 1.47 Msun Temp: 6350 K Radius: 1.84 Rsun HAT-P-7b Mass: 1.8 MJ Semimajor axis: 0.0379 AU Orbital Period: 2.2047298 days Radius: 1.4 RJ Temperature: 2650 K 2

  3. KEPLER HAS THE PRECISION TO DETECT EARTH-SIZE PLANETS

  4. KEPLER IS THE NEXT STEP IN THE SEARCH FOR LIFE IN OUR GALAXY. By 2013, Kepler should; • Determine whether Earths in the Habitable Zones of other stars are common or rare. • Guides the next step in our exploration of our Milky Way Galaxy

  5. What Does HAT-P7b Sound Like? We extracted the harmonic components from Quarter 1 light curves of variable stars Extended these time series to and equivalent of 3.5 years of data Wrote out as WAV files sampled at 8192 Hz What HAT-P7b “sounds” like: Another interesting star: Image by Carter Roberts (1946-2008) 10

  6. Music From the Stars (2) Image by Carter Roberts (1946-2008) 11

  7. A VERY HOT COMPANION LIGHT CURVE OCCULTATION: 1300 ppm TRANSIT; 500ppm Star temperature = 9400K Companion temperature = 12,200K Companion size = 0.8 RJ

  8. BINARY WITH CIRCUMBINARY PLANET? Binary Star Planet ? LOS x Focus of ellipse

  9. Ultra Deep Field (Hubble Space Telescope)
