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 کاملHorsing around on Saturn.
On the basis of simple statistical mechanical models, the prevailing view of the rings of Saturn is that they are unstable and must therefore have been formed rather recently. In this paper, we argue that the Saturn rings and inner moons are in much more stable orbits than previously thought and, therefore, that they likely formed together as part of the initial formation of the solar system. T...
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...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
