In 2003,
Michel Mayor's team announced the discovery of a new planet,
HD 10647 b, in Paris at the XIX IAP Colloquium
Extrasolar Planets: Today & Tomorrow. The
Anglo-Australian Planet Search team initially did not detect the planet in 2004, though a solution was made by 2006. The
CORALIE data was finally published in 2013. The
IRAS infrared space
telescope detected an
excess of infrared radiation from the star, indicating a possible
circumstellar disk. Out of the 300 nearest Sun-like stars, the disk has the highest fractional
luminosity out of all of them. It is unusually bright, but not unusually massive; the lower bound of the mass is 8 times that of the Earth. The inclination of the disk is relatively high, and the disk is asymmetrical, being more extended in the northeast direction than the southwest. It extends from 34
astronomical units (AU) at the inner edge to 134 AU at the outer edge. The inner edge is sharp, suggesting the existence of a planet that carved out the edge. HD 10647 b, with a semimajor axis of about 2 AU, is too far to be responsible. However, other potential planets may be responsible for this feature. If HD 10647 b shares the same orbital inclination as the disk (), its mass should be about 1.07
Jupiter masses, close to its minimum mass of 0.90 Jupiter masses. There is some evidence for an additional, warm
asteroid belt-like component further in, at 3 to 10 AU away from the star. ==Notes==
