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.
If you know a star’s rotation, you can find its age. Today’s authors look at stars for which this isn’t the case.
Today’s authors carefully check their evidence for the first potential exomoon detection.
Today’s authors use asteroseismology to determine differential rotation in two sun-like stars.
