We perent radio flux measurements at 5 GHz for a sample of RS CVn-type chromospherically active binary systems made from 1988 to 1992 using the NRAL broad-band interferometer (BBI). The derived radio luminosities are consistent with previous observations but show that radio flaring is a common feature which will affect the results of rotation-activity studies. ... Key words: stars: activity - stars: late type - stars: binaries: close - stars: flare - stars: variables - stars: radio continuum ...

My research interests are focussed on the theory and modelling of accretion processes as well as star and planet formation mechanisms. I am particularly interested in the stability properties of accretion discs, the generation of MHD turbulence and associated angular momentum transport, disk - planet interactions and the origin and characteristics of jets and winds from accreting systems . ... These results have been published in Salmeron & Wardle, 2005, M.N.R.A.S., 361: 45-69. ...

... The available observational data on masses and/or luminosities of binary components and the current models for different chemical compositions of Pop I stars were used to improve the mass-luminosity relation for stars of moderate masses. ... This technique was also applied to decompose the low-mass components of several stars suspected to be unresolved binaries. ... The method is based on the minimum determination technique applied to functions of several variables covering a limited range of values...

... arXiv.org . astro-ph . ... We fit the near-infrared to radio spectral energy distributions of 30 luminous and ultra-luminous infrared galaxies with pure starburst models or models that include both starburst and AGN components to determine important physical parameters for this population of objects. In particular we constrain the optical depth towards the luminosity source, the star formation rate, the star formation efficiency and the AGN fraction. ...

... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...

The idea of component-oriented programming is that in the course of implementation of various software projects a programmer (or a programmers team) accumulates a library of reused software fragments that are used in different projects. ... To solve such problems there are some special syntax means in Actor Prolog that support component-oriented programming. ... A package in Actor Prolog is a set of classes linked by implication. ... Actor Prolog supports visual component-oriented programming. ...

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). ...

Sloan Digital Sky Survey Telescope Technical Note 19970527 Walter Siegmund . ... Pointing Error Budget . ... The interleaved strips and adjacent stripes overlap about 1 arc minute. ... However, a 2-D pointing accuracy of 3 arc seconds RMS leads to acceptibly uniform overlap and minimises the number of cases that require special handling (Table 3). ... A guide fiber bundle diameter of 16.5 arc seconds and a pointing accuracy of 3 arc sec RMS results in 99% initial success in acquiring guide stars. ...

The latter is an algebraic variety with the given field of rational functions and an infinitely transitive regular action of a group of algebraic automorphisms generated by unipotent algebraic subgroups. ... Quotient groups. ... Since over R there exist irreducible non-connected varieties, we cannot have even one-transitivity of any connected group of automorphisms. ...
