Gyrochronology ages for ~100000 stars & host stars

Listed in IVOA Registry (Virtual Observatory)

Gyrochronology, the field of age dating stars using mainly their rotation periods and masses, is ideal for inferring the ages of individual main-sequence stars.

Description

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.

With this model, we obtain gyrochronology ages for ~100000 stars within 1.5kpc of the Sun with period measurements from Kepler and Zwicky Transient Facility and 384 unique planet host stars. A simple code is provided to infer gyrochronology ages of stars with temperature and period measurements.
