Rich Física, Astronomía y Matemáticas Bulge data analysis stellar content kinematics and dynamics We report on the advancements of a project which studies the Galactic bulge throught the kinematics of the stellar population in several low foreground extinction windows. In order to obtain the kinematics of as many stars as possible we have used the technique of proper motions in several fields wi th Hubble Space Telescope ( HST ) observations available. These proper motions have been complemented with radia l velocities whenever possible. Our preliminary results consist of a sample of ∼ 140,000 proper motions with accuracies > 1( mas yr − 1 ) distributed over 10 fields strategically placed at both ends of the Galactic bulge/bar. 2015 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57150514017 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.46 |
