... 8, ``Celestial Mechanics'', 2002 An approximate projection of confidence ellipsoids of space objects positions onto the celestial sphere A. P. Baturin Research Institute of Applied Mathematics and Mechanics, Tomsk, Russia The approximate method of calculation of a visible border of probable motion regions (PMR) for space objects (SO) has been considered. ... As a result, the simple analytical expressions for border points of PMR projection onto the celestial sphere have been obtained. ...

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. ...

... Contact . ... Neutron stars and black holes aren't all they've been thought to be. In fact, neutron stars can be considerably more massive than previously believed, and it is more difficult to form black holes, according to new research developed by using the Arecibo Observatory in Arecibo, Puerto Rico. read more ..

... Credit Copyright: International Astronomical Union Explanation: How many planets are in the Solar System? This popular question now has a new formal answer according the International Astronomical Union (IAU): eight. Last week, the IAU voted on a new definition for planet and Pluto did not make the cut. Rather, Pluto was re-classified as a dwarf planet and is considered as a prototype for a new category of trans-Neptunian objects . ...

The absorption of MHD waves due to the cusp (or the slow) resonance is studied numerically and the obtained results are discussed with respect to a possible application to conditions that are typical for the solar corona. The considered configuration is composed of two homogeneous regions separated by an inhomogeneous slab through which all physical parameters of the medium change continuously according to an initially prescribed distribution. ...

For particles of very large sizes, scattering can be considered as a result of interference of the rays having multiple reflections and refractions according to the laws of geometrical optics. ... The papers [ 413 , 414 ] presented a method where the scattering field was expressed via the field at the particle surface using the Huygens-Kirchhoff principle, and reflection and refraction laws were employed to find the unknown field (the approach was called physical optics approximation). ...

... The pg_trgm contrib module provides functions and index classes for determining the similarity of text based on trigram matching. ... A zero result indicates that the two words are completely dissimilar, and a result of one indicates that the two words are identical. real show_limit() Returns the current similarity threshold used by the '%' operator. ... Tsearch2 Integration Trigram matching is a very useful tool when used in conjunction with a text index created by the Tsearch2 contrib module. ...

Next: Other deconvolution tasks Up: Image Deconvolution Previous: Computation . If you have used multi-frequency synthesis in the imaging stage, you will have to have considered a fly in the ointment - the flux density of the source will vary with frequency (as well as spatially). For detection and low dynamic-range work, mild spectral variation can generally be ignored. ... The Miriad deconvolution task mfclean can be used to avoid this distortion. ...

... In this poster we propose a hypothesis that within fixed assumptions about internal physics (opacity, thermodynamics, nuclear reactions) a strict relation between the surface helium abundance and the entropy of the adiabatic part of the convective zone exists for all solar models. This hypothesis is verified with models under simplified physics (Christensen­Dalsgaard 1988) and with six evolutionary models computed by Christensen­Dalsgaard (1992). ... 1990, Christensen­Dalsgaard 1991). ...
