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?
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.
Interplanetary collisions can explain a number of phenomena in our own solar system — here’s evidence of such a crash shaping the formation of two distant planets. Translate from an Astrobitos bite by Elena Gonzales Egea.
Could exocomets be causing these strange shaped lightcurves?
There are a lot of Sun-like stars in the universe. Are they as identical as the name suggests, or are there important differences between them?
