Nota di contenuto

What can the sun tell us about stellar activity? -- On the origin of stellar magnetism -- Stellar activity and rotation -- Solar and stellar convection -- Photospheric structure in solar-type stars -- Solar and stellar chromospheres -- Solar an stellar coronae -- Stellar vs. solar activity: The case of pre-main sequence stars -- Winds in late type stars and the solar wind -- Observations from space vs. ground based observations: Advantages and disadvantages -- New ideas about granulation based on data from the solar optical universal polarimeter instrument on spacelab 2 and magnetic data from big bear solar observatory -- Future prospects of stellar and solar physics from space.

Sommario/riassunto

These proceedings bring together ideas from solar and stellar physics. The sun is near enough for rather detailed observations and one chapter is devoted to the more recent experimental data from observations from space. On the other hand the multitude of stars provides a wide range of physical parameters to test hypotheses in solar and stellar astrophysics. The reader will find an illuminating overview of these fields ranging from the dynamo in the convection zone to the stellar envelopes and winds in the outer regions. In particular the importance of small-scale magnetohydrodynamic processes for the activity phenomena plays an important role in the contributions to this volume. For both students and researchers the general introduction by N. O. Weiss makes an excellent guide to this very active field of research. (See also Lecture Notes in Physics Vol. 291.).

Sommario/riassunto

This book constitutes the thoroughly refereed post-conference proceedings of the 34th International Workshop on Graph-Theoretic Concepts in Computer Science, WG 2008, held in Durham, UK, in June/July 2008. The 30 revised full papers presented together with 3 invited paper were carefully reviewed and selected from 76 submissions. The papers feature original results on all aspects of graph-theoretic concepts in Computer Science, e.g. structural graph theory, sequential, parallel, and distributed graph and network algorithms and their complexity, graph grammars and graph rewriting systems, graph-based modeling, graph-drawing and layout, diagram methods, and support of these concepts by suitable implementations.
