• Stellar magnetic field — A stellar magnetic field is a magnetic field generated by the motion of conductive plasma inside a main sequence (hydrogen burning) star. This motion is created through convection, which is a form of energy transport involving the physical… …   Wikipedia

• 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… …   Wikipedia

• Doppler imaging — Not to be confused with Doppler ultrasound. Inhomogeneous structures on stellar surfaces, i.e. temperature differences, chemical composition or magnetic fields, create characteristic distortions in the spectral lines due to the Doppler effect.… …   Wikipedia

• Starspot — Starspots are equivalent to sunspots but located on other stars. Spots the size of sunspots are very hard to detect since they are too small to cause fluctuations in brightness. Observed starspots are in general much larger than those on the Sun …   Wikipedia

• RS Canum Venaticorum variable — RS Canum Venaticorum variables are a type of variable star. They are close binary stars having active chromospheres which result in variations in their observed luminosity. The period of variations is, in general, close to the rotational period… …   Wikipedia
