   Oct 21, 2024 · The discovery of the ancient star J0524-0336 is reshaping our understanding of stellar evolution, particularly because of its unexpectedly high lithium content. Typically, older stars lose lighter elements like lithium as they age, making this star a compelling anomaly. Researchers used spectroscopy to analyze the star and confirmed its unusual lithium abundance. This has led

   Jan 5, 2016 · As stars age, this spin slows down due to the star’s magnetic field acting on its stellar wind, which is a flow of gas moving away from the star. The loss of mass, as the flowing gases get caught in the magnetic field and spin outward until they are ejected, affects the Sun’s angular momentum and causes the slowdown.

   Dec 9, 2020 · Young or low-mass stars will flare brightly and frequently, whereas older or more massive stars flare infrequently. The rotation of a star also plays a role here, as a faster rotation is believed to be related to more star spots and higher levels of magnetic activity. As stars age and lose angular momentum their rotation will slow down, thus ...

   Do aging stars keep their vigor as they age?

   • SLOWDOWN Sunlike stars start as fast-spinning balls of gas (illustrated at left). As this type of star ages, its spin slows and it puffs up, before dying as a nebula (middle and right). But the spin of these aging stars might not slow as much as thought. CAMBRIDGE, Mass. — Stars may keep some of their youthful vigor as they age.

   Do older stars spin slower?

   • Like a ballet dancer extending their arms, the magnetized stellar wind gradually slows a star’s rotation. The idea that older stars spin slower has been a central assumption in stellar astronomy for decades. But over the past several years, a team of astronomers has begun to rewrite the ballet of stars.

   How do astronomers determine a star's age?

   • But it’s difficult to pinpoint a star’s age. Theories of stellar evolution predict that young stars rotate quickly but slow as they age and lose angular momentum, a process called spinning down. So astronomers often use a star’s spin rate to estimate age.

   Does a star's spin rate predict age?

   • Theories of stellar evolution predict that young stars rotate quickly but slow as they age and lose angular momentum, a process called spinning down. So astronomers often use a star’s spin rate to estimate age. Recently, though, data have emerged that raise questions about whether that aging scenario is correct.

   Why do stars flare at a given age?

   • In short, the flare activity at a given age is likely to depend on the stellar mass. Understanding stellar flares helps us understand the evolution of stars like our Sun, as well as the conditions on exoplanets around low-mass flaring stars (such as the TRAPPIST-1 system ).

   How does age affect a star's magnetic activity?

   • As stars age and lose angular momentum their rotation will slow down, thus also reducing their magnetic activity. Today’s authors take a big leap in the direction of understanding stellar flares. In a previous study, they showed that flaring activity declined with age.
