... 8, ``Celestial Mechanics'', 2002 The Lyapunov spectra in spin--orbit dynamics V. V. Kouprianov, I. I. Shevchenko Pulkovo Observatory, St. Petersburg, Russia We study the problem of the chaotic rotation of a minor planetary satellite around its mass center, in the planar and spatial settings. ... The rest of the satellites in our set rotate regularly in synchronous resonance; but, in any case, each of them had passed through the stage of chaotic rotation. ...

The commands ROTATE/CLOCK , ROTATE/COUNTER_CLOCK and FLIP/IMAGE enable to perform any rotation by a multiple of 90 degrees and image flipping without interpolating the pixel values. The command REBIN/ROTATE can be used for any rotation but in the general case will interpolate the pixel values. ...

... In this section, we develop a physical model of the secondary as a disk that is centrifugally supported in the radial direction and hydrostatically supported in the vertical direction. We assume that the disk is vertically isothermal and well mixed. ... where is the mean molecular mass of the gas, is the orbital period at the outer edge of the disk in years, and all of the mass of the secondary has been assumed to be concentrated near its center, so the Keplerian approximation is valid. ...

Dynamical chaos in the problem of magnetic jet collimation O. Yu. ... In the paper of Bisnovatyi-Kogan (2007) magnetic collimation resulting from torsional oscillations of a cylinder with elongated magnetic field and periodically distributed initial rotation around the cylinder axis was considered. ... Space and time periods of oscillations depend on the conditions of jet formation: the length-scale, the amplitude of the rotational velocity, and the strength of the magnetic field. ...
