Text of report The subject if our report is the influence of the structure and physics of the uppermost superadaibatic layers on the oscillational spectrum of p-modes. ... In our report we will try to use a most simple representation of the spectrum, plotting the differences between theoretical (that is models') and observational frequencies against a frequency. ... It allow us to focused on the effects of the uppermost layers and ignore possible sophistications from effect of more deeper layers. ...

EVOLUTION OF RADIO NOISE STORMS AT COMPRESSED DYNAMIC SPERTRA . ... An analysis of large-scale variations of noise storm intensity and frequency spectra has been carried out basing on IZMIRAN dynamic radio spectra compressed in time. It is shown that various enhancements and weakening of noise storms as well as changes of their frequency spectrum appear to be caused by effects of coronal mass ejections on sources of the emission or/and electron acceleration in the corona. ...

The plasma relaxes for a crossing time (118 Myr) and then we inject mass and x-momentum to a central control cylinder and experiment with the jets power: velociB µG RM maps We calculate RM= 812 dl rad m-2 from the jets' con3 tact discontinuity to the end of the domain along different viewing angles. ...

... We present new progress in our extensive pro ject mCPod (On­line database of photometric observations of magnetic CP stars), which was initiated five and a half years ago (Mikulґ et. al, 2007). ... The database consists of two parts, the Data and the References. In the References one finds the sources of data, the bibcodes including links to the corresponding papers, names of comparison and check stars (if available), the number of observations in individual filters (see Fig. ...

... 8, ``Celestial Mechanics'', 2002 Dynamic evolution of resonance orbits of exoplanets in system 47 Uma B. R. Mushailov, A. A. Kaloshin Sternberg Astronomical Institute, Moscow, Russia The orbits of the major and minor planets of the Solar system indicate that their dynamic evolution is essentially influenced by the effects of orbital reso­ nance interactions. ... One may expect that the orbital resonances can exist not only in the Solar system, but also in other star systems. ...

... In electron-positron colliders, effect of the lattice modification by opposing bunch focusing on the equilibrium radiation emittance is important at high values of the space charge parameter, so one should correctly evaluate this dynamic radiation emittance of the weak beam, which may differ a lot from the nominal emittance, already in the linear beam-beam force model. ... The linearized beam-beam force is equivalent to focusing insertion in linear lattice of the collider. ...
