Research on Star Determination and Hertzsprung Diagram Drawing Design of Bi Cluster based on Clustering Algorithm
This article aims to use the characteristics of stars in the same star cluster in the hipparcos catalogue to systematically cluster stars based on their right ascension,right ascension,distance,as well as their own velocities and angles.By comparing the results obtained from the system clustering algorithm with the actual position and shape of the bixing cluster in the sky,a total of 112 stars that may belong to the bixing cluster were identified,and the DBSCAN clustering algorithm was used for verification.By using the principle of triangulation,the parallax angle is converted into distance,and then the apparent magnitude and distance are converted into absolute magnitude using the Simpson formula.Finally,using the color index as the horizontal axis and the absolute magnitude as the vertical axis,the hertzsprung diagram of the bi star cluster and the Hertzsprung diagram of all stars in the catalog are plotted.
