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...

Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space...

Measurements of the time variation in stellar activity can be useful for determining the differential rotation rates of a star. A star with a magnetic...

rotation affects stellar optical absorption-line spectra through line broadening caused by lines being differently Doppler-shifted across the stellar...

In astrophysics, stellar nucleosynthesis is the creation of chemical elements by nuclear fusion reactions within stars. Stellar nucleosynthesis has occurred...

Rotation or rotational/rotary motion is the circular movement of an object around a central line, known as an axis of rotation. A plane figure can rotate...
