All stars rotate, and stellar rotation can impact a star’s evolution greatly. However stellar rotation remains poorly understood. Can studying stellar pulsations shed light on this topic?
A previously unexplained branch of cooling white dwarfs is likely a traffic jam caused by an 8 billion year delay in cooling. A heavy isotope of neon settling down into the core of the star could be the source.
By determining the precise ages of stars in our galaxy, today’s Astrobite focuses on piecing together a detailed history of our own Milky Way.
Today’s authors take a multi-faceted approach to characterising a benchmark subgiant star using asteroseismology, interferometry, and spectroscopy.
Could the surface of Earth’s only natural satellite hold the key to understanding early activity of our own star? Today’s paper investigates the Moon’s composition to find out more.
A look at how magnetic braking can erase the extended main sequence turn-off feature in old stellar clusters.
