The present paper considers resonant slow waves in 1D non-uniform magnetic flux tubes in dissipative MHD. ... From these analytical solutions we obtain the fundamental conservation law and the jump conditions for resonant slow waves in dissipative MHD. The validity of the ideal conservation law and jump conditions obtained by Sakurai et al. (1991) for static equilibria and Goossens et al. (1992) for stationary equilibria is justified in dissipative MHD. ...

Next: Identification and Analysis of Binary Star Systems using Probability Theory . ... We present a computing code for modelling energy flux distributions, photometric indices and spectral line profiles of (non-)radially pulsating Main-Sequence stars. ... In the case of slowly rotating stars one can use the zero-rotation approximation to describe stellar pulsations. Such a model was used already by Cugier, Dziembowski & Pamyatnykh (1994) to study nonadiabatic observables of Cephei stars. ...
SLIDE 1 Coherent beambeam e#ects study. ... He has shown that a finite length (in other words equal to # # ) of colliding bunches can lead to the coupling of synchrobetatron modes in the beambeam system, and thus a headtail type instability of colliding bunches may arise. ... These modes have been observed in di#erent machines. ... SLIDE 5 Figure shows the dependence of the measured and calculated synchrobetatron mode tunes on the beam current for equal electron and positron bunch intensities. ...

Some results of the study of shells (arcs) in the near-nucleus region of comet Hale-Bopp are presented. ... All these calibration procedures gave an opportunity to draw on each image a polar coordinate grid ( rho, phi ), where rho - the distance of the shell point from the nucleus (cometocentric distance in 10 4 km), phi - the polar angle measured with respect to the axis directed to the Sun. ...
