Do You Know: Which Is The Oldest Star In The Universe?
WebMay 21, 2024 · Astronomers think it has another 5 billion years to go before it swells into a red giant star that will engulf the Earth and then shrink into a white dwarf star. Because HD 140283 is neither on the main sequence nor a red giant, its early position in the Hertzsprung–Russell diagram has been interpreted with its data and theoretical models of stellar evolution based on quantum mechanics and the observations of processes in millions of stars to infer its apparent old age. For field stars (as opposed to stars in clusters), it is rare to know a star's luminosity, surface temperature, and composition precisely enough to get a well-constrained val… WebApr 5, 2024 · Because a star's true brightness is related to both its mass and the amount of metals present in its nuclear fuel, Bond was able to estimate HD 140283's age at 14.46 billion years, give or take... is dwp universal credit
