WebThe effects of viscosity and thermal conductivity on the stability of rotating stellar models in general relativity theory are investigated. The equations of motion for the perturbed fluid … Stellar rotation is the angular motion of a star about its axis. The rate of rotation can be measured from the spectrum of the star, or by timing the movements of active features on the surface. The rotation of a star produces an equatorial bulge due to centrifugal force. As stars are not solid bodies, they can also … See more Unless a star is being observed from the direction of its pole, sections of the surface have some amount of movement toward or away from the observer. The component of movement that is in the direction of the … See more During formation Stars are believed to form as the result of a collapse of a low-temperature cloud of gas and dust. As the cloud collapses, conservation of angular momentum See more After a star has finished generating energy through thermonuclear fusion, it evolves into a more compact, degenerate state. During this process the dimensions of the star are significantly … See more Equatorial bulge Gravity tends to contract celestial bodies into a perfect sphere, the shape where all the mass is as close … See more A close binary star system occurs when two stars orbit each other with an average separation that is of the same order of magnitude as their diameters. At these distances, more … See more • Staff (February 28, 2006). "Stellar Spots and Cyclic Activity: Detailed Results". ETH Zürich. Archived from the original on March 16, 2008. Retrieved 2008-03-16.

This motion is created through convection, which is a form of energy transport involving the physical movement of material. A localized magnetic field exerts a force on the plasma, effectively increasing the pressure without a comparable gain in density. As a result, the magnetized region rises r…
