Magnetic braking in low-mass stars
… is driven by angular momentum loss due to magnetic braking (MB). Although the same fundamental mechanism likely drives MB in all these systems, a holistic study of such a mechanism has not been carried out before. Here I aim to investigate whether observations of CV evolution and the spins …

The role of magnetic braking and ambipolar diffusion in the formation of interstellar cloud cores and protostars
… a fundamental unsolved problem in astrophysics. Magnetic fields, which dominate thermal-pressure as a source of support against self-gravity in interstellar molecular clouds, are an important regulator of star-formation. We study the formation and contraction of fragments (or cores) in …

Ambipolar Diffusion in Interstellar Clouds: One-Dimensional, Isothermal Collapse
… (i) the angular momentum problem, and (ii) the magnetic flux problem. We have previously emonstrated by detailed calculations that magnetic braking by itself can resolve the angular momentum problem (at least for binary stars and, most likely, for single stars as well) during the early, …

Magnetic Coupling between a “Hot Jupiter” Extrasolar Planet and Its Pre-Main-Sequence Central Star
… short-period pile-up of extrasolar planets, the magnetic torque of a pre-main-sequence central star on a single orbiting "hot Jupiter" planet is calculated. The star's magnetic field is modeled as a dipole magnetic field. The time-dependent stellar radius is calculated for four different stellar …

K-Star rapid rotators and the detection of relatively young multiple K-Star systems
… contraction phase followed by spin down due to magnetic braking where typical K stars would be expected to spend up to a few hundred million years before slowing down to a rotation period of more than 2 days.

Disk-magnetosphere interaction in X-ray binaries
Binary X-ray pulsars are strongly magnetic neutron stars accreting matter from a companion star. The strong magnetic fields of the neutron stars guide the accreting plasma to the magnetic poles, and X-ray pulsations result from the rotation of the beamed emission at the magnetic poles through the …

Tidal interactions between planets and stars
… orbits. We also analyse the effects of stellar magnetic braking. We then discuss the implications of our results for the importance of Rossiter-Mclaughlin effect observations. In the second part, we study the mechanisms of tidal dissipation in solar-type stars. In particular, internal gravity …

Development of Novel Eddy Current Dampers for the Suppression of Structural Vibrations
… damping to the membrane structure is to use magnetic damping. Magnetic dampers function through the eddy currents that are generated in a conductive material that experiences a time varying magnetic field. However, following the generation of these currents, the internal resistance of the …
