Abstract:
The empirical relations between rotation period, chromospheric
activity, and age can be used to estimate stellar age. To calibrate
these relations, we present a catalog, including the masses and ages
of 52321 FGK dwarfs, 47489 chromospheric activity index logRHK+,
6077 rotation periods Prot, and variability amplitudes Sph, based on
data from LAMOST DR7, Kepler, and Gaia Data Release 3. We find a
pronounced correlation among Prot, age, and [Fe/H] throughout the
main-sequence phase for F dwarfs. However, the decrease of logRHK+
over time is not significant except for those with [Fe/H]<-0.1. For
G dwarfs, both Prot and logRHK+ are reliable age probes in the
ranges ∼2-11Gyr and ∼2-13Gyr, respectively. K dwarfs exhibit a
prominent decrease in logRHK+ within the age range of ∼3-13Gyr
when the relation of Prot-τ is invalid. These relations are very
important for promptly estimating the age of a vast number of stars,
thus serving as a powerful tool in advancing the fields of exoplanet
properties, stellar evolution, and Galactic archeology.
Description:
We use atmospheric parameters of LAMOST DR7 (see V/156) derived by the
data-driven Payne (DD-Payne) approach (Xiang+ 2019, J/ApJS/245/34).
The absolute magnitude and luminosity are from Gaia DR3 (see I/355).
See Section 2.
