Transiting Extrasolar Planets

Observations of the planets HD 209458b and TrES-1b using the NFO webscope

Presentation by Rozmin Daya

Work by Rozmin Daya and Dr. Lacy

background
Background
  • Extrasolar planets can be detected via the transit technique.
  • This can give information about: the planet’s orbital period, radius, mass, density, and distance from it’s parent star.
goals of project
Goals of Project
  • Test the limits of the NFO telescope.
  • Improve on the known orbital elements for HD 209458b and TrES-1b.
project description
Project Description
  • Transits of the planets will be photographed.
  • The images will be measured using the program Measure.
  • Light curves for the stars will be constructed using Measure.
  • The light curves will be analyzed using the program EBOP.
  • This will yield orbital information for the planets.
the nfo telescope
The NFO Telescope
  • Located in Silver City, NM
  • Robotic
  • Uses a 24” Cassegrain reflector and a 2k by 2k CCD camera on the back end
  • Can observe using B, V and R filter.
  • Processing: [raw – bias – (dark * exposure / 120)] * 10,000 / flat
measuring the images
Measuring the Images
  • View images
  • Select a pattern
  • Measure the series
  • View the light curve the program has constructed
the good stuff
The Good Stuff
  • A series of images was obtained 07-15-2005 UT for HD 209458
  • Graphs were constructed for each color
  • The transit was from 6:07 UT to 9:07 UT
  • We photographed from 6:46 UT to 8:16 UT
conclusion
Conclusion
  • The NFO telescope can observe the transits of extrasolar planets.

Future Work

  • TrES-1b
  • Continued observation of HD 209458b
