NGC 3201 - Wikipedia

Because NGC 3201 is a less dense globular cluster, far from undergoing core collapse, it is believed to harbor a substantial black hole population in its core. Indeed, a few black holes have been detected in this cluster, orbiting nearby stars. In a study from 2024, the movement of stars near the cluster's core derived from data gathered by the Hubble Space Telescope and the European Space Agency's Gaia spacecraft indicated that NGC 3201 has a sub-cluster of stellar … WebSelect search scope, currently: articles+ all catalog, articles, website, & more in one search; catalog books, media & more in the Stanford Libraries' collections; articles+ journal articles & other e-resources WebOne of the primary differences between the Pleiades cluster, shown in Figure19.17(a) in the textbook, and Omega Centauri, shown in Figure19.18(a), is that the Pleiades cluster is much...
