Found that by far the most unusual extrasolar planets.

World Scientific reports [tech.] News: an amateur astronomer and professional astronomers, an international planet search team has found a planet they interested in the planet's most unusual ever recorded extrasolar planets .one of the 13 times the mass of Jupiter, less than four days will run a lap around its star. .Interesting features in many areas <P> </ P> <P> U.S. "XO Plan" (XO Project) researchers recently held at the Honolulu Conference of the American Astronomical Society published their latest findings - .one called "XO-3b" of the planet. .Rice University astronomer Christopher Johns - Ke Luer in the General Assembly on behalf of the research team published their findings. .He said: "The planet is indeed very strange. In the Congress very appropriate time to publish the study found, because the 'XO programs' core is running in Honolulu, Hawaii, two small telescopes." < ./ P> <P> "XO Plan" director, Baltimore Space Telescope Science Institute (STScI) astronomer 彼得麦克库洛夫 (Peter McCullough) said: "In so far discovered 200 extrasolar planets were, XO .-3b in many areas of the features are surprised. It is so close so far found that the quality of the track's largest planet, given its distance from the star in orbit distance, we were surprised to find this track is not circular, and .is oval. "麦克库洛夫 said that given the XO-3b in all aspects of the peculiar characteristics, which may stimulate the formation of planetary astronomers interest. .</ P> <P> Johns - Ke Luer, said: "We are quite interested, XO-3b is the quality of the planets and 'brown dwarf', the dividing line between. At present, how to divide the astronomical community in the brown .dwarf debate in full swing on the issue. "Any stellar mass are large enough to melt hydrogen, has this quality it is the star of stars. .The brown dwarf's mass is far below the requirements to become stars. .</ P> <P> "XO Plan" to find the third satellite transiting planets </ P> <P> Johns - Ke Luer is a Rice University associate professor of physics, astronomy, and he said: "The controversy lies in the .the lower end of the range of values. Some people think that deuterium can melt objects are brown dwarfs, in theory they are equivalent to 13 Jupiter mass. Some people say that quality does not matter, it is important that the object is a self-formed .or as part of the formation of planetary systems. "</ P> <P> according to their quality, are eligible to compete any one brown dwarf planet status to most of the planet searchers can easily find that this is because astronomy .observing the sky in their home, they are actually not in the direct search for planets, but looking around its orbit due to gravity and the rotation of the planet rock star, the bigger the planet, it produces more intense shaking. .So, ten years ago using this "radial velocity" (radial velocity) method of planet hunters, began to scan the sky looking at the shaking of the star, hoping to find a large number of brown dwarfs. .But their desire to never become a reality, the quality of the astronomical community will object that the lack of super-state called "brown dwarf desert" (brown dwarf desert). .</ P>.
