stellar motion
Смотреть что такое "stellar motion" в других словарях:
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 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 drift — Stellar drift, or the motion of stars, is a necessary result of the lack of an absolute reference frame in special relativity. The term is used mainly in science fiction, however; in particular, the phenomenon affects stargates in the Stargate… … 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

Motion (physics) — Motion involves change in position, such as in this perspective of rapidly leaving Yongsan Station In physics, motion is a change in position of an object with respect to time. Change in action is the result of an unbalanced force. Motion is… … Wikipedia
Stellar dynamics — is the branch of astrophysics which describes in a statistical way the collective motions of stars subject to their mutual gravity. The long range of gravity and the slow relaxation of stellar systems prevent the use of the methods of statistical … 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
Stellar engine — Diagram of a Class C Stellar Engine to scale built around a sun like star. It consists of a partial Dyson swarm composed of 5 Dyson Rings of solar collectors (the Class B component), and a large statite Shkadov thruster (the Class A component).… … Wikipedia
