The Perihelion Precession of Saturn, Planet X/Nemesis and MOND
We show that the anomalous retrograde perihelion precession of Saturn !& " , recently estimated by different teams of astronomers by processing ranging data from the Cassini spacecraft and amounting to some milliarcseconds per century, can be explained in terms of a localized, distant body X, not yet directly discovered in the remote periphery of the solar system. From the determination of its ...
متن کاملA Hot Saturn Planet Orbiting Hd 88133, from the N2k Consortium
The N2K consortium is carrying out a distributed observing campaign with the Keck, Magellan and Subaru telescopes, as well as the automatic photometric telescopes of Fairborn Observatory, in order to search for short-period gas giant planets around metal-rich stars. We have established a reservoir of more than 14,000 main sequence and subgiant stars, closer than 110 pc, brighter than Based on o...
متن کاملSearch for Transits of a Short-Period, Sub-Saturn Extrasolar Planet Orbiting HD 46375.
Precise brightness measurements of HD 46375 have been acquired with an automatic telescope to search for transits of its short-period, sub-Saturn extrasolar planet. Transits of the companion do not occur, indicating that the inclination of the orbit i is less than 83 degrees and sini is less than 0.992. This upper limit on sini still preserves the possibility that the mass of the planet is less...
متن کاملThe Saturn System
Saturn is a giant planet surrounded by numerous rings, many satellites, and a large magnetosphere. Although the Saturn system bears a general resemblance to the Jovian system, it has many unique attributes which provide new insight into the formation and evolution of planetary systems. This introductory chapter provides an overview of the results of recent studies of the Saturn system which are...
متن کاملBlack Saturn
Using the inverse scattering method we construct an exact stationary asymptotically flat 4+1-dimensional vacuum solution describing “black saturn”: a spherical black hole surrounded by a black ring. Angular momentum keeps the configuration in equilibrium. Black saturn reveals a number of interesting gravitational phenomena: (1) The balanced solution exhibits 2-fold continuous non-uniqueness for...
