Rotation and pseudo-rotation [PDF]
General Relativity and Gravitation, 2005 Eigenvectors of stress-energy tensor (the source in Einstein's equations) form privileged bases in description of the corresponding space-times. When one or more of these vector fields are rotating (the property well determined in differential geometry), one says that the space-time executes this rotation.

Journal of High Energy Physics, 1999 We present a class of spacetime rotations that preserve a proportion of spacetime supersymmetry. We then give the rules for superposing these rotations with various branes to construct rotating brane solutions which preserve exotic fractions of supersymmetry.

Rotations and rotation matrices [PDF]
Acta Crystallographica Section D Biological Crystallography, 2001 In molecular replacement, a model, described as a list of orthogonal coordinates, is to be moved into a new position and orientation. The orthogonal coordinate system also has to be related to the crystallographic system, which may not be orthogonal, and crystallographic symmetry must be considered, which applies to coordinates expressed as fractions ...

The dependence of differential rotation on temperature and rotation [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2005 AbstractWe use Doppler imaging techniques to determine the dependence of starspot rotation rates on latitude in an homogeneous sample of young, rapidly rotating solar analogues. A solar-like differential rotation law is used, where the rotation depends on sin2θ, where θ is the stellar latitude. By including this term in the image reconstruction process,

Rotating Alfvén waves in rotating plasmas
Journal of Plasma Physics, 2023 Angular momentum coupling between a rotating magnetized plasma and torsional Alfvén waves carrying orbital angular momentum (OAM) is examined. It is demonstrated not only that rotation is the source of Fresnel–Faraday rotation – or orbital Faraday rotation effects – for OAM-carrying Alfvén waves, but also that angular momentum from an OAM-carrying ...

Rotational Modes in A Uniformly Rotating Star [PDF]
International Astronomical Union Colloquium, 1980 AbstractThe linear adiabatic oscillations of a uniformly rotating star are examined with respect to a co-rotating frame of reference. It is shown that time-independent displacement fields are allowed and can be represented as toroidal fields. The time-dependent oscillation modes are governed by a system of differential equations of the fourth order in ...
