Stellar Evolution and Trajectory of The Pleiades

Through data collected from a variety of research papers done in the past such as spectrographs and computations of movements (Kinematic Age of Moving Groups, Yuan C. 1976). We created a simulation that would take a theoretical approach to predicting the future movements of the star cluster known as The Pleiades or Seven Sisters. The simulation was created using a previous simulation done by Jason Wang as reference, the code was modified to suit our experiment and take more factors into account in order to create an accurate result. Such factors vary from the star’s individual mass to the Milky Way’s gravitational momentum. The simulation runs on python 3.11 using modules such as pygame for the visual results and another module being created for the stars functions and attributes. Our final simulation runs for around 8 seconds and takes into account approximately 36 million years. Alongside the visual representation of the stars movements, the code’s terminal also prints the amount of years that have passed and how much the mass has changed from one of the stars to use for the observations. Our observations concluded that our hypothesis of drastic attribute change was wrong and what was really drastic was the change in location after its movements. These results were verified using previous research done that traces the stars’s past movements and aligning our trace to compare the movement pattern the stars have. Using our results and observation, a visual depiction was created using Photoshop of how the stars would look after approximately 36 million years.
