Gyrochronology ages for ~100000 stars & host stars

However, due to the lack of physical understanding of the complex magnetic fields in stars, gyrochronology relies heavily on empirical calibrations that require consistent and reliable stellar age measurements across a wide range of periods and masses. In this paper, we obtain a sample of consistent ages using the gyro-kinematic age-dating method, a technique to calculate the kinematics ages of stars.

Using a Gaussian process model conditioned on ages from this sample (~1-14Gyr) and known clusters (0.67-3.8Gyr), we calibrate the first empirical gyrochronology relation that is capable of inferring ages for single, main-sequence stars between 0.67 and 14Gyr. Cross-validating and testing results suggest our model can infer cluster and asteroseismic ages with an average uncertainty of just over 1Gyr, and the inferred ages for wide binaries agree within 0.83Gyr.
