How do stars in a cluster change with time

WebFeb 23, 2024 · This cluster was formed after the collision of two large clusters of galaxies, one of the most energetic events known in the universe since the big bang. Because the major components of the cluster pair — stars, gas and the apparent dark matter — behave differently during collision, scientists were able to study them separately. WebAs a star consumes its nuclear fuel, its source of energy changes, as do its chemical composition and interior structure. These changes cause the star to alter its luminosity …

Star clusters are large groups of stars held together by self-gravitation. Two main types of star clusters can be distinguished: globular clusters are tight groups of ten thousand to millions of old stars which are gravitationally bound, while open clusters are more loosely clustered groups of stars, generally containing fewer than a few hundred members, and are often very young. Open clusters becom… WebGlobular clusters, on the other hand, are very densely packed with stars. In open clusters, the gravitational pull of all the stars taken together is not strong enough to keep the stars bound to the cluster. Over time, the …
