... 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 exoplanet HD 209458b has a mass more than 200 times Earthт??s and has a diameter greater than Jupiterт??s. It orbits its star at about an eighth of the distance Mercury orbits the sun, so the exoplanet takes only 3.5 days to complete an orbit. This proximity to a star means that the planet is hot, perhaps 1000ТАC, hence it is classed as a т??hot Jupiterт?? ...

Isaak Newton (1642 - 1727). ... During 1665 - 1667 Newton made his three main discoveries: the method of fluxings and quadratures (differential and integral calculus, explanation of the light nature and the law of gravitation). ... In 1668 Newton built the first reflecting telescope. The big lens telescope gave indistinct image with painted edges. ... The scientist considered this problem indisolved and suggested a mean against chromatic aberration: a mirror must be used instead of objective lens. ...

Comets necessarily obey the same physical laws as every other object. ... If one considers only two bodies -- either the Sun and a planet, or the Sun and a comet -- the smaller body appears to follow an elliptical path or orbit about the Sun, which is at one focus of the ellipse. ... Another quantity that is conserved is called angular momentum. ... Comets simply are bodies which in general have more angular momentum per unit mass than do planets and therefore move in more elongated orbits. ...

... Satellites of the planets are assigned a provisional designation (indicating year of discovery) by the Central Bureau for Astronomical Telegrams ( CBAT ) upon satisfactory demonstration of the existence of a new object. ... In the past, Comets were first given a provisional designation, consisting of the year and a lowercase letter indicating the order of discovery in the year (e.g., 1994a was the first comet discovered or recovered in 1994, 1994b the second, etc.) ...
