Dilhan Eryurt was the the first Turkish astronomer to work at NASA and the only woman at Goddard during her tenure. She fundamentally changed our understanding of the Sun.
Is the gravitational constant really constant? Today’s authors investigate using an 11 billion year old star.
Today’s authors take a multi-faceted approach to characterising a benchmark subgiant star using asteroseismology, interferometry, and spectroscopy.
We need to know the radii of M-dwarfs to study their exoplanets, and the models aren’t much help.
Most binary stars probably formed at the same time, meaning all stars in the same system should have the same age. The authors of this paper analyze a stellar binary system where one star appears to be lying about its age, as one star appears 3 billion years older than its companion.
