Planetary System
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 & Tormorrow* . 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 analysed in literature in 2012.
The IRAS infrared space telescope detected an excess of infrared radiation from the star, indicating a possible circumstellar disk. Using this data and later observations with the Spitzer Space Telescope, Infrared Space Observatory and the Atacama Pathfinder Experiment implies that the disk is located at 25 Astronomical units and has a thin (0.02 AU), ring-like structure, with the sharp cutoff in the disk suggesting a planet. Additionally, a much longer wavelength suggests the existence of a much wider belt of material, analogous to the Kuiper belt. The hierarchy of this system is somewhat reminiscent of that of Epsilon Eridani, without an inner asteroid belt.

Famous quotes containing the words planetary and/or system:
“What is a television apparatus to man, who has only to shut his eyes to see the most inaccessible regions of the seen and the never seen, who has only to imagine in order to pierce through walls and cause all the planetary Baghdads of his dreams to rise from the dust.”
—Salvador Dali (1904–1989)
“I need not say what match I would touch, what system endeavor to blow up; but as I love my life, I would side with the light, and let the dark earth roll from under me, calling my mother and my brother to follow.”
—Henry David Thoreau (1817–1862)
