Dear group,
One of the latest exoplanet discoveries (2007) involves TrES-3 in Hercules. What is of great interest surrounding this discovery is the exoplanet's proximity to its parent star and its degenerative orbit. In other words, at some point this exoplanet will not be available for study due to its orbit and impending collision into its sun. What makes the photometry of this exoplanet most challenging is the fact that its host star is very dim at magnitude 12.17 and the transit depth of 25 mmag translates to very small changes in the overall dimness of the parent star during transit. I am delighted to present you with a light curve for TrES-3 taken with a well-known 160 mm refractor (LOL!) and which most beautifully illustrates the 105-minute transit. I contacted a couple of individuals a priori surrounding this transit and I was told that it is not possible in the slightest given the dim magnitude of the parent star, the transit depth and my small aperture. Well, no pain, no gain. For the light-curve in two-formats as well as a finder chart, I kindly direct you to http://www.perseus.gr/Astro-Photomet...3-20080503.htm .... There are additional exoplanet transits over the next few months and which I will certainly be pursuing. Clear skies! Anthony. |
