Collisionless microinstabilities in stellarators. II. Numerical simulations [PDF]
Physics of Plasmas, 2013 Microinstabilities exhibit a rich variety of behavior in stellarators due to the many degrees of freedom in the magnetic geometry. It has recently been found that certain stellarators (quasi-isodynamic ones with maximum-J geometry) are partly resilient ...

Neoclassical transport simulations for stellarators [PDF]
Physics of Plasmas, 2011 The benchmarking of the thermal neoclassical transport coefficients is described using examples of the Large Helical Device (LHD) and TJ-II stellarators.

Stellarators and Optimised Stellarators
Fusion Technology, 1998The properties of a classical stellarator will be described and the need to optimise stellarators will be motivated. The principles of optimisation will be presented. W7-AS, a partly optimised modular stellarator, will be briefly introduced and some results with relevance to its optimised properties will be summarised.

Results from helical axis stellarators [PDF]
Physics of Plasmas, 2001 Helical axis stellarators produce magnetic surfaces of high rotational transform and moderate shear solely by means of external currents, with the promise of high b.

IEEE Transactions on Plasma Science, 1958
The basic concepts of the controlled thermonuclear program at Project Matterhorn, Princeton University are discussed. In particular, the theory of confinement of a fully ionized gas in the magnetic configuration of the stellarator is given, the theories of heating are outlined, and the bearing of observational results on these theories is described.

Plasma Physics and Controlled Fusion, 1993
The local electron and ion heat transport as well as the particle and impurity transport properties in stellarators are reviewed. In this context, neoclassical theory is used as a guideline for the comparison of the experimental results of the quite different confinement concepts.

Observing a stellar radius basically means observing a center-to-limb intensity variation. The significance and properties of center-to-limb variations, common approximations, the correlation with optical-depth radii in extended-photophere stars, and direct measurements of angular (interferometry, lunar occultation) and absolute diameters (binary ...

A Sun-like star undergoes magnetic cyclic reversal shown by field lines colored by the longitudinal magnetic field. Shifts in positive and negative polarity demonstrate large-scale polarity changes in the star. One such cycle is shown, and at the end of the visualization, the magnetic poles are reversed. Wreath-like areas in the magnetic field could be
