Plenary on Latest Results from the Kepler Mission [October 15, 2012 @ 2:20-2:55 PM PDT]
| Title | Latest Results from the Kepler Mission | |

| Abstract | As the Kepler Mission completes the end of its third year of science observations, calibrated time series data of increasing length are becoming available that make possible the detection of planetary candidates smaller than Earth and candidates with orbital periods nearing one year. Further, the greater capability and sophistication of the pipeline analyses improve the completeness of the results and provide better estimates of the parameter distributions. The most recent data release on 28 July 2012 (Quarters 6 through 9) adds an additional ¾ year of observations so that most planetary candidates with orbital periods as long as 273 days now show at least 3 transits. Data for an additional year (i.e., Quarters 10 through 13) are scheduled to be released on 28 October 2012. A first look at the size, period, and semi-major axis distributions of these data will be presented. Summaries of the planets confirmed, candidates that are being actively analyzed, and the methods being used to verify and confirm planets will be discussed. The Extended Kepler Mission operations begin on 1 October 2012 and many changes in mission focus and operations, data release, and science community participation are being implemented and will be outlined. Funding for this Discovery mission is provided by NASA's Science Mission Directorate. |

Underlying Architecture of Planetary Systems Based on Kepler Data
Julia Fang (Univ. of California, Los Angeles)| Title | Underlying Architecture of Planetary Systems Based on Kepler Data: Number of Planets and Coplanarity | |
| Author Block | Julia Fang1, J. L. Margot1
1University of California, Los Angeles. | |
| Abstract | We investigated the underlying architecture of planetary systems by deriving the distribution of planet multiplicity (number of planets) and the distribution of orbital inclinations based on the sample of planet candidates discovered by the Kepler mission. The scope of our study included solar-like stars and planets with orbital periods less than 200 days and with radii between 1.5 and 30 Earth radii, and was based on Kepler planet candidates detected during Quarters 1 through 6. Our analysis improves on previous work by including all available quarters, extending to 200-day periods, and fitting models to observables such as normalized transit duration ratios that contain information on mutual orbital inclinations; these improvements lend to a deeper investigation of the intrinsic distributions of planetary systems. We created models of planetary systems with different distributions of planet multiplicity and orbital inclinations, simulated observations of these systems by Kepler, and compared the number and properties of the transits of detectable objects to actual Kepler planet detections. Based on the underlying distributions of our best-fit models, 75-80% of planetary systems have 1 or 2 planets with orbital periods less than 200 days. In addition, over 85% of planets have orbital inclinations less than 3 degrees. This high degree of coplanarity is comparable to that seen in our Solar System, with the exception of Mercury. These results provide important constraints and insights into theories of planet formation and evolution. |

| Abstract | The Planet Hunters (http://www.planethunters.org) citizen science project uses the power of human pattern recognition via the World Wide Web to identify transits in the Kepler public data. Planet Hunters uses the Zooniverse (http://www.zooniverse.org) platform to present visitors to the Planet Hunters website with a randomly selected ~30-day light curve segment from one of Kepler's ~160,000 target stars. Volunteers are asked to draw boxes to mark the locations of visible transits with multiple independent classifiers reviewing each 30-day light curve segment. Since December 2010, more than 170,000 members of the general public have participated in Planet Hunters contributing over 12.5 million classifications searching the 1 1/2 years of publicly released Kepler observations. Planet Hunters is a novel and complementary technique to the automated transit detection algorithms, providing an independent assessment of the completeness of the Kepler exoplanet inventory. We report the latest results from Planet Hunters, highlighting in particular our latest efforts to search for circumbinary planets (planets orbiting a binary star) and single transit events in the first 1.5 years of public Kepler data. We will present a status report of our search of the first 6 Quarters of Kepler data, introducing our new planet candidates and sharing the results of our observational follow-up campaign to characterize these planetary systems.

The Very Compact Five Exoplanet System KOI-500: Mass Constraints and Implications
Darin Ragozzine (Univ. of Florida)| Title | The Very Compact Five Exoplanet System KOI-500: Mass Constraints from TTVs, Resonances, and Implications | |
| Author Block | Darin Ragozzine1, Kepler Team
1University of Florida. | |
| Abstract | NASA's Kepler Mission has discovered thousands of planet candidates, including nearly 900 in systems with multiple transiting planet candidates. Such multi-transiting systems are extremely valuable for understanding the combined physical and orbital characteristics of planetary systems. Most of these candidates are in Systems with Tightly-packed Inner Planets (STIPs), which are characterized by a concentration of dynamically tight planets near 0.1 AU. There are about 10 Kepler systems that show 5 or more planets transiting, though it is not yet fully clear whether these are unusual or just a high multiplicity tail of a continuous distribution of STIPs. The first known 5-candidate system was KOI-500 and we here present results which confirm and/or validate all 5 planets and discuss its several distinct properties. Even for a STIP, KOI-500 has a very compact architecture, with all 5 planets within 0.1 AU. The estimated radii of the 1.0, 3.1, 4.6, 7.1, and 9.5-day period planets are 1.3, 1.4, 1.5, 2.4, and 2.6 Earth radii, respectively. The outer four planets are very near unique and interlocking three-body resonances. The outer planets also show Transit Timing Variations (TTVs), allowing for good mass constraints and helping to fill in the exciting small planet mass-radius relation. The inclinations of the planets are generally well constrained, which, in combination with TTVs, allow for an investigation into the true mutual inclinations of this system. We will present an overview of the results of our analysis of the KOI-500 system and place it in context of other STIPs discovered by Kepler and Doppler surveys. |
