Stars have an innate twinkle caused by gas rippling from their core to their surface. Researchers have now converted these oscillations into sound to help figure out how they happen.
Stars have an innate twinkle that comes from gas rippling from the core to the surface. Researchers have now converted these oscillations into sound to help figure out how it happens.
at Northwestern University in Illinois and his colleagues have used a computer model to create the first 3D simulation of this rippling energy, enabling them to quantify the intervals and frequencies at which twinkling happens.At the heart of a star is a whirlwind of hot and cold gasses churning and mixing and getting pushed outwards in ocean-like waves.
It turns out massive stars of different sizes are just like different instruments from the same family, says Anders.

Astronomers Have a New Trick to Work out the Age of StarsDetermining the age of a star is surprisingly tricky and has wide error bars. It's only inside star clusters that you get a chance to accurately measure a star's age since they all had the exact origin and age. But a new technique hopes to discover the age of stars by measuring their rotation. As stars get older, their rotation rate slows down. By plotting the rotation rates of stars in clusters against their known ages, they can apply it to individual stars which aren't in clusters.
