  1. A Photometric Search for Young Planetary Systems Frank M. Alston Junior, Electrical Engineering Major Tennessee State University Advisor: Prof. Gregory W. Henry Tennessee State University Center of Excellence in Information Systems

  2. How is this research contributing to science? • Our search for planets beyond our solar system seeks to answer the question “Are we alone?” • Finding young planetary systems gives us insight into the formation and evolution of our own solar system. • Gives the possibility of discovering additional transiting planets ( HD209458, the first transiting planet, was discovered at TSU) • Our results will help to confirm new planets discovered around young stars with the SIRTF satellite and the Keck telescope on Hawaii.

  3. The SIRTF satellite searching for dust disks around young stars

  4. Detection of Planetary Reflex Motion x Stephen Henry

  5. Twin Keck I and Keck II 10-meter telescopes on Mauna Kea

  6. Zsolt Kovari Konkoly Observatory

  7. The T12 Automatic Photometric Telescope

  8. Periodogram analyses of selected stars

  9. Phase Curves of selected stars

  10. Summary • Analyzed APT observations of 93 young stars • Discovered 71 stars (76%) were variable • Successfully measured rotation periods for 55 of the variables (59%) • Did not find any new transiting planets • Our results will be crucial for the identification of new planets around these 93 young stars with the SIRTF satellite and the Keck telescope
