... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...

As the sun sets in the west each evening, Jupiter, the largest planet in our Solar System, is rising in the east in the constellation of Aries, where it is visible throughout the night setting just before sunrise. ... On 28 October the Earth comes between the Sun and Jupiter, in opposition, meaning as the Sun sets in the sky Jupiter will rise. ... Also this month rising into the sky in the early hours of the morning is Mars the Red planet....

... Running Rings Around a Planet . ... Saturn's delicate rings have caught human eyes for over three centuries. ... Now we know, thanks to the Voyager space probes, that Saturn's rings consist of thousands of "ringlets," each made of chunks of ice ranging in size from dust to boulders [see "Rally Around the Ring," March/April 1995, p. 10]. ... The appearance of Saturn's rings to us ground-hugging Terrans is changing constantly. ... Saturn's diameter is 120,000 kilometers, so how large are the rings? ...

... 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. ...
