How do giant stars form
WebApr 13, 2024 · The gas and dust that swirl around a star during its formation are critical to forming planets around it. The dust contains heavy elements such as carbon and iron that form the cores of planets. Scientists think planets start off as grains of dust smaller than the width of a human hair. A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity … See more A star becomes a giant after all the hydrogen available for fusion at its core has been depleted and, as a result, leaves the main sequence. The behaviour of a post-main-sequence star depends largely on its mass. See more There are a wide range of giant-class stars and several subdivisions are commonly used to identify smaller groups of stars. Subgiants Subgiants are an entirely separate spectroscopic luminosity class (IV) from giants, but share … See more • Interactive giant-star comparison. See more

WebOct 15, 2024 · How Do Giant Stars Form? Although giant stars are a different kind of star from average main-sequence stars, it isn’t actually formed right away. Instead, stars go through the main-sequence phase for a long time, perhaps billions of years, before entering the giant phase, which lasts much shorter than the main-sequence phase. WebThe density of stars makes these observations hard to do, but at least one IMBH candidate about 2,000 times the mass of the Sun has been identified in a globular cluster.

In 2024 astronomers found something strange — a gas giant in a very close orbit around a low-mass star, an M dwarf dubbed GJ 3512. The discovery was an anomaly, because there shouldn’t have been enough material around the star to form such a big planet in the first place.
