Catastrophe theory and stellar systems

Astrophysics, 1987
The manifestation of a gravothermal catastrophe for a stellar system containing a massive central body is examined from the point of view of catastrophe theory. It is shown that the catastrophe of A/sub 2/ type that holds for a system without a massive center persists in this case too and does not become a cusp.

Theory of advanced stellarators

Plasma Physics and Controlled Fusion, 1999
The main features of advanced stellarators are the optimized coil system which can be extrapolated to reactor size, improved properties of plasma equilibrium with reduced Shafranov shift and a stability limit which is sufficient to meet the requirements of a commercial fusion reactor.

ROTE Stellar Theory

This paper presents a deterministic theory of stellar structure based on the Resonant Order Theory of Everything (ROTE). Anchored at the φ-spiral, the Sun appears at n ≈ 60.3 for mass and n ≈ 40.5 for temperature, enabling accurate prediction of stellar properties from first principles. The ROTE Stellar Spiral unifies white dwarfs, main sequence stars,

High beta stellarator stability theory

The Physics of Fluids, 1979
An analytic study of the stability of a straight diffuse high beta stellarator with arbitrary wall corrugation is presented. It is found that a solvability condition for the equilibrium of such a plasma is intimately related to a sufficient condition for stability.

Theory of stellar oscillations

This lecture covers the theoretical basics of stellar oscillations. The first part focuses on solar-like oscillations, which are the core targets of the PLATO mission: after a thorough introduction about the properties of the seismic spectrum of solar-like stars and how they relate to their internal structure and fundamental stellar parameters, we ...
