New work may have implications for our own Solar System, as they indicate that our own sun might be on the cusp of a transition in its magnetic field. Credit: © kevron2001 / Fotolia
A recently developed method for determining a star’s age needs to be recalibrated for stars older than our sun. This is due to new information about the way older stars spin, as spin rate is one of the few windows into stellar ages Findings indicate sun might be on cusp of a transition in its magnetic field.
Just like planets, stars rotate around an axis. As stars age, this spin slows down due to the star’s magnetic field acting on its stellar wind, ie flow of gas moving away from the star...
