How do globular clusters form
WebThe three basic types of clusters astronomers have discovered are globular cluster s, open cluster s, and stellar association s. Their properties are summarized in Table 22.3. As we … Globular clusters are generally composed of hundreds of thousands of low-metal, old stars. The stars found in a globular cluster are similar to those in the bulge of a spiral galaxy but confined to a spheroid in which half the light is emitted within a radius of only a few to a few tens of parsecs. They are free of gas … See more A globular cluster is a spheroidal conglomeration of stars. Globular clusters are bound together by gravity, with a higher concentration of stars towards their centers. They can contain anywhere from tens of thousands to … See more The formation of globular clusters is poorly understood. Globular clusters have traditionally been described as a simple star population … See more Hertzsprung–Russell diagrams (H–R diagrams) of globular clusters allow astronomers to determine many of the properties of their populations of stars. An H–R diagram is a graph of a large sample of stars plotting their absolute magnitude (their See more When a globular cluster comes close to a large mass, such as the core region of a galaxy, it undergoes a tidal interaction. The difference in gravitational strength between the nearer and further parts of the cluster results in an asymmetric, tidal force. A "tidal shock" … See more The first known globular cluster, now called M 22, was discovered in 1665 by Abraham Ihle, a German amateur astronomer. The cluster Omega Centauri, easily visible in the southern sky with the naked eye, was known to ancient astronomers like See more In contrast to open clusters, most globular clusters remain gravitationally bound together for time periods comparable to the lifespans of most of their stars. Strong tidal interactions with other large masses result in the dispersal of some stars, leaving behind "tidal … See more Astronomers are searching for exoplanets of stars in globular star clusters.

The center of the cloud pulls in material from its surroundings until it becomes dense enough to trigger star formation. From this study, they discovered the stars on the outskirts of the clusters actually are the oldest.

Plus, … WebJan 26, 2024 · Over time, the leftover dust and gas around a star blow away or form into other cosmic bodies like planets, asteroids, and comets. Gravity then pulls the young stars together, and they begin to orbit each other. Star clusters can contain as few as ten stars or as many as millions of stars.
