Sounding Solar and Stellar Interiors: General Introduction
in the many senses of the word. It is a tremendous amount of fun with a really large number of interesting problems, vigorous dialectic between observations and theory, rapid progress, fantastic observational opportunities, and extraordinarily stimulating colleagues. It is grand, in its phenomenally rapid development, the challenges that it presents, and the importance of the problems that it a...
متن کاملOn the magnetic sounding of planetary interiors
Two ways have been suggested for using the magnetic field of a planet to estimate the radius of its electrically conducting core, assumed spherical and concentric with the planet's surface. In the frozen flux method, the core radius is assumed to have the value rFF for which the integrated unsigned radial magnetic flux, from the sphere of that radius, is most nearly constant in time. In the fla...
متن کاملStellar interiors - physical principles, structure, and evolution
Bargaining with reading habit is no need. Reading is not kind of something sold that you can take or not. It is a thing that will change your life to life better. It is the thing that will give you many things around the world and this universe, in the real world and here after. As what will be given by this stellar interiors physical principles structure and evolution, how can you bargain with...
متن کاملStable magnetic fields in stellar interiors
We investigate the 50-year old hypothesis that the magnetic fields of the Ap stars are stable equilibria that have survived in these stars since their formation. With numerical simulations we find that stable magnetic field configurations indeed appear to exist under the conditions in the radiative interior of a star. Confirming a hypothesis by Prendergast (1956), the configurations have roughl...
متن کاملMagnetotelluric Sounding of Terrestrial Planet and Satellite Interiors
Introduction. Electromagnetic (EM) sounding of the Moon and the Galilean satellites has yielded important insights on the interior structures of these bodies [e.g., 1-7]. These investigations measured magnetic fields only and required auxiliary information on the nature of the source fields. The magnetotelluric (MT) method, by measuring both magnetic and electric fields, can perform soundings f...
