제목: Gyrochronology: a route to the ages of cool field stars​​​​​​​​​​​​​​​​

The ages of astronomical objects, while not directly measurable, are of use in constructing chronologies, and the key to understanding origins. The ages of cool field dwarfs, although important in a Galactic context, are especially challenging to obtain. I will present a route to the ages of such objects that is called “Gyrochronology,” one based on the measured rotation periods of such stars.​
