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: Data reduction Up: Spectral observations and data Previous: Observations with the KPNO . Follow-up spectroscopy with this telescope was conducted as a back-up for a main program which needed photometric conditions. So, the observations presented here were obtained in non-photometric conditions and the absolute flux calibration of the data is unreliable. The Cassegrain focal reducer CAFOS of the 2.2m telescope was used with a long slit of 300 3 and a grism of 187 ? ...

... Aromatic dust emission features and emission lines from molecular and atomic hydrogen are detected but they are not particularly strong. The dominant spectral features are emission lines from moderately ionized species of argon, neon, and sulfur, which are used to determine the physical conditions in the ionized gas. The ionized gas excitation shows strong variations on parsec scales, some of which can plausibly be associated with individual hot stars. ... ADS Citation Query . ...

. I will briefly summarise the methods to estimate the magnetic field strengths of different types of neutron stars and the caveats associated with them. In this context I will present some recent results we have obtained in finding the limits to the field strengths of accreting millisecond X-ray pulsars from the interaction between the accretion disk and neutron star magnetosphere.

Next: A Universal Diagram for Up: ``Ecology'' of Magnetic Rotators Previous: The Corotation Radius . The interaction of a magnetic rotator with the surrounding plasma to a large extent depends on the relation between the four characteristic radii: the stopping radius, , the gravitational capture radius,   , the light cylinder radius,   , and the corotation radius,   . ... Hence, the classification of the interaction regimes may well mean the classification of magnetic rotators. ...

Abstract -- The strengths of magnetic fields in interstellar gas clouds are obtained through observations of the circular polarization of spectral line radiation. ... To infer information about these irregularities from the observational data, we develop statistical relationships between the rms values of the irregular component of the magnetic field and spatial variations in the circular polarization of the spectral line radiation. ...

. Present section of the package enables one to perform following actions: . — . To make selection out of the total number of elements in accordance with the conditions imposed on some element or on a variety of elements. — . to sort the set of elements in order of ascending or descending value of any element. — . to draw the histogram of element distribution for obtained selection. — . To construct dotty picture of minor planet distribution in two– or three–dimension space of elements.

... Fitting the observed dependence includes calculations of the polarization cross-sections averaged over particles orientation and size distribution, their normalization and the comparison of obtained dependencies with Serkowski's curve representing observational data for a chosen star. ... Variations of the polarization factors with wavelength are shown in Fig. 16 for homogeneous spheroidal particles with PF orientation. ... The distinction between prolate and oblate spheroids is also clearly seen. ...

... Because the DMR instrument is differential and every pixel is multiply sampled, sky maps are produced by solving a coupled system of linear equations (the normal equations) to minimize a chi-squared. ... This is reflected in the algebraic form of the normal equations matrix, so that, if one were to diagonalize the matrix, one would find a single eigenvector whose eigenvalue was identically zero, and the associated eigenvector, viewed as a sky map, would have a constant value. ...
