Exoplanetary Scratchpad

[SysBP Img]

Young system with an extremely far flung visually detected planet. Found at 650 AU and 11 times Jupiter's mass. Furthest out known planet around a single star. It orbits further out than planet accretion theories allow for. There appear to be no other nearby planets or stars which could have flung the planet from a closer orbit. The star was found later on to be a binary star. The planet could have been further in and then expelled by one of them. The ratio of star to planet mass is 1 to 100, lower to be formed like a binary star, whose ratios are no more than 1 to 10. The planet is 13 MY old and still glowing from its formation. It was detected with a thermal infrared camera on Magellan telescope in Chili and confirmed by historical Hubble data. Star has a debris disk 50 AU wide similar to the Kuiper Belt, fat on one side and skinny on the other side. The planet is highly tilted with respect to its plane, so it must have been moved to its present location. Closer in planets were not detected. A passing star could be responsible for the lop sided belt and far out orbit of the planet.
