wrote: Hello group; I updated my web site with August 17 extrasolar transit of newly discovered planet TrEs-4. This is my best result so far and the shape of the transit is quite definite. This planet is 1.7 times larger than Jupiter and has an average density only of 0.2 g/cm^3. The depth of the transit was of 0.01 manitudes and the precision reached is +- 0.0014 magnitudes (at the beginning, and 0.002 magnitudes at the end, because the lower altitude). Here is the direct link to the transit:http://www.danielegasparri.com/eng/t...lar/tres-4.htm. Clear skies! -- Daniele Gasparri Perugia (Italy)www.danielegasparri.com A solar system transit is the most immediate experience of Copernican reasoning as it represents the point where a planet ,in an inner orbital circuit , overtakes the slower moving Earth with the central Sun in the background - http://www.kwastronomy.com/images/Ve...sit-3-1-2c.jpg http://www.youtube.com/watch?v=Vgvwj...elated&search= Copernicus and Kepler did not have telescopes to admire these brilliant heliocentric events and they relied on the faster Earth overtaking the slower moving outer planets to infer the Earth's orbital motion between Venus and Mars around the central star - http://antwrp.gsfc.nasa.gov/apod/ima...2000_tezel.gif The next event in 2012 should be promoted as a once in a lifetime chance to appreciate Copernican reasoning directly,instead it will diluted to an astrological theme of Venus 'crosses the face of the Sun" and nothing else. |
