Stellar motion, also known as stellar dynamics, is the study of the motion and interactions of stars within galaxies. This field of research focuses on understanding the movement of stars within galaxies, including how they orbit around each other, their motions through the galaxy, and the gravitational interactions that influence their trajectories. Stellar motion research often involves measuring the velocities and positions of stars, studying their orbital dynamics, and analyzing the effects of gravitational forces from other stars or celestial bodies. By studying stellar motion, researchers can gain insights into the structure and evolution of galaxies, star formation processes, and the dynamics of stellar systems. This research area is important for understanding the overall dynamics of the universe and the processes that shape the evolution of galaxies and their constituent stars.
