Recent Developments in Stellarator Physics

Nuclear Technology - Fusion, 1983
Experimental and theoretical work on the stellarator concept has established its position as the best alternate concept for fusion power. Its plasma properties are comparable to, or better than, those obtained in comparable tokamak devices. Confinement and transport should be adequate for reactor operation, with high-..beta..

The physics of stellar core collapse

Astrophysics and Space Science, 1988
The hydrodynamics that develops during the infall of the core of a massive star at the end of its hydrostatic evolutionary epoch can have a profound effect on its subsequent dynamical history. In this paper the important processes governing the infall hydrodynamics are explored both semi-analytically and numerically with the aim of explaining the ...

Multi-Dimensional Processes In Stellar Physics

2020
When one has to deal with fluid flows, magnetic fields or heat transfer in stars, one faces the partial differential equations that govern these processes. These phenomena are naturally multi-dimensional and their study requires new and sophisticated models.

Stellar Evolution Physics

2012
This volume explains the microscopic physics operating in stars in advanced stages of their evolution and describes with many numerical examples and illustrations how they respond to this microphysics. Models of low and intermediate mass are evolved through the core helium-burning phase, the asymptotic giant branch phase (alternating shell hydrogen and

Physics at the stellarator--tokamak interface

Plasma Physics and Controlled Fusion, 2011
A tokamak is never exactly axisymmetric, either because of field errors or because the magnetic field is intentionally perturbed–something that is becoming increasingly popular for controlling the plasma edge. Conversely, a stellarator generally lacks symmetry but may be `quasisymmetric', meaning that the strength (but not the direction) of the ...

Stellar Spots — Physical Implications [PDF]

, 1981
Studies of certain late-type stars have revealed evidence for appreciable changes in their photospheric radiation. These stars are rotating much more rapidly than the Sun and/or are younger, and exhibit much enhanced examples of many kinds of solar activity, such as flares.

Physical Conditions in the Stellar Interior

2016
This chapter establishes the main equations of the stellar structure, namely, the continuity equation and the hydrostatic equilibrium equation, and gives some estimates of the average density, pressure, and temperature. Finally, a discussion is made of the thermodynamic equilibrium and the stellar energy.

Physical mechanisms in stellar pulsations

The Journal of the Acoustical Society of America, 1985
Stars evolve from their births to their deaths by converting their store of hydrogen to helium, and then much of this helium is fused to heavier elements such as carbon, oxygen, and up to iron. During this evolution, the stellar mass may decrease by a stellar wind mass loss, the radius usually greatly increases, and the radiation luminosity emitted at ...
