Rotational clock for stars needs recalibration

A recently developed method for determining a star's age needs to be recalibrated for stars older than our sun, new work from a team of astronomers indicates. This is due to new information about the way older stars spin, as spin rate is one of the few windows into stellar ages. These findings have implications for our solar system, as they indicate the sun might be on the cusp of a magnetic field transition.
