متن کاملThe orbital motion of the Arches cluster – clues on cluster formation near the Galactic center
The Arches cluster is one of the most massive, young clusters in the Milky Way. Located inside the central molecular zone in the inner 200 pc of the Galactic center, it formed in one of the most extreme star-forming environments in the present-day Galaxy. Its young age of only 2.5 Myr allows us to observe the cluster despite the strong tidal shear forces in the inner Galaxy. The orbit of the cl...
متن کاملPhotometry of the Arches Cluster near the Galactic Center
We present Near-IR photometry of the Arches cluster, a young and massive stellar cluster near the Galactic center. We have analyzed the high resolution (FWHM ∼ 0.2) H and K ′ band images in the Galactic Center Demonstration Science Data Set, which were obtained with the Gemini/Hokupa’s adaptive optics (AO) system. We present the color-magnitude diagram, the luminosity function and the initial m...
