Calibration of the [C/N] and [Y/Mg] chemical clocks with asteroseismic ages from the TESS space mission
E. Pakštienė, G. Tautvaišienė, V. Bagdonas +8
Context. Stellar ages are typically very difficult to estimate for field stars. New empirical methods, based on abundance ratios of chemical elements, are emerging and need to be c…
