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
Stellar kinematics — is the study of the movement of stars without needing to understand how they acquired their motion. This differs from stellar dynamics, which takes into account gravitational effects. The motion of a star relative to the Sun can provide useful… … Wikipedia
Stellar wobble — is a variation in the position of a star due to the gravitational influence of another body orbiting it. Stellar wobble is visible as a Doppler redshift in the star s spectrum or as a motion of the star in the plane of the sky. The Doppler shift… … Wikipedia
Stellar classification — In astronomy, stellar classification is a classification of stars based on their spectral characteristics. The spectral class of a star is a designated class of a star describing the ionization of its chromosphere, what atomic excitations are… … Wikipedia
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 evolution — Life cycle of a Sun like star Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most… … Wikipedia

Young stellar object — (YSO) denotes a star in its early stage of evolution. This class consists of two groups of objects: protostars and pre main sequence stars. Sometimes they are divided by mass massive YSO (MYSO), intermediate mass YSO and brown dwarfs.YSO are… … Wikipedia
