Rotational Fresnel drag - or orbital Faraday rotation in a rotating magnetised plasma is uncovered and studied analytically for Trivelpiece-Gould Whistler-Helicon waves carrying angular momentum (OAM). Plasma shown to introduce non-zero phase shift between OAM-carrying eigenmodes with opposite helicities, similarly the phase-shift spin associated classical effect at rest. By examining dispersio...

We explore the forces and conservation laws that govern motion of a hockey puck slides without friction on smooth, rotating, self-gravitating spheroid. The earth's oblate spheroidal shape (apart from small-scale surface features) is determined by balancing gravitational hold it together against centrifugal try to tear apart. earth achieves this when apparent force puck, defined as vector sum fo...

Vesta’s giant south polar impact basin Rheasilvia exhibits a spiral deformation pattern. We tested whether or not the Coriolis force has caused the curved features of the pattern. For this we mapped the curved features and calculated the velocities along them using the Coriolis theory. The resulting velocities indicate that the Coriolis force is a candidate to have caused the spiral deformation...

We present results from a study of the eclipsing, colliding-wind binary V444 Cyg that uses a combination of X-ray and optical spectropolarimetric methods to describe the 3-D nature of the shock and wind structure within the system. We have created the most complete X-ray light curve of V444 Cyg to date using 40 ksec of new data from Swift, and 200 ksec of new and archived XMMNewton observations...

The most consistently useful simple model for the study of odd deformed nuclei, the particle-rotor model (strong coupling limit of the core-particle coupling model) has nevertheless been beset by a long-standing problem: It is necessary in many cases to introduce an ad hoc parameter that reduces the size of the Coriolis interaction coupling the collective and single-particle motions. Of the num...

Micromachined gyroscopes for measuring rate or angle of rotation have attracted a lot of attention during the past few years for several applications. They are widely used to detect orientation in space, including automotive applications for ride stabilization and rollover detection; some consumer electronic applications, such as video-camera stabilization, virtual reality, and inertial mouse f...

When reaching movements involve simultaneous trunk rotation, additional interaction torques are generated on the arm that are absent when the trunk is stable. To explore whether the CNS compensates for such self-generated interaction torques, we recorded hand trajectories in reaching tasks involving various amplitudes and velocities of arm extension and trunk rotation. Subjects pointed to three...

In a rotating environment, goal-oriented voluntary movements are initially disrupted in trajectory and endpoint, due to movement-contingent Coriolis forces, but accuracy is regained with additional movements. We studied whether adaptation acquired in a voluntary, goal-oriented postural swaying task performed during constant-velocity counterclockwise rotation (10 RPM) carries over to recovery fr...
