... HD 10180: Richest Yet Planetary System Discovered . ... Our Solar System has the most planets of any known star, most probably because it is so hard to detect planets around other stars . Sensitive measurements, though, have now uncovered a slight but complex wobble of the Sun-like star HD 10180 indicating that it has at leave five planets and possibly more, making it the richest extra-solar planetary system yet known. ...

... Research . ... GPI Data Pipeline . ... GPI . ... My research focuses on high contrast imaging of circumstellar material: disks, envelopes, jets, and substellar companions. ... The second, harder challenge is achieving sufficiently high contrast: scattered light from circumstellar dust is faint, usually less than a percent of the total flux, sometimes far less. ... In addition to planet detection, GPI will also feature a polarimetric imaging mode for studies of circumstellar dust disks. ...

The extrasolar planets discovered to this time are believed to be giant gaseous planets similar to Jupiter and Saturn. ... This, together with the large masses of the extrasolar planets discovered to date, has led researchers to conclude that all the extrasolar worlds are giant gaseous planets similar to Jupiter and Saturn. ...

... Since planets are expected to form out of the material in disks around young stars, the formation of a planet will thoroughly alter the structure of the circumstellar disk of their host star, forming significant gaps in the radial distribution of matter around the star. Additionally, processing of solids (annealing/crystallization) and changes in the overall gas/dust ratio are thought to happen during the planet formation process and are believed to alter the observational signature of the disk. ...
