I am inventing the field of gyrochronology so that it applies to all stars in all stages of evolution, not just the ones that have the masses of Sun-like stars.
Venus, Mercury, Earth, Uranus, Saturn... the thousands of evolving stars found by Kepler (which are called exoplanets by the dogma). They all have a spot in the grand evolutionary history of our galaxy.
They all spin, and so much more information can be gathered from their spin rate than what the dogma allows for. It is time to open the flood gates.
