Age-mass distribution for sample A (silver) and sample B (black), showing the tight relationship for the seismic red-giant stars (sample B). The location of the Sun is identified by its usual symbol (⊙), assuming an age of 4.6 Gyr. The dashed red line follows the τ ∝ M¹−^η scaling, where η = 3.5 (cf. Kippenhahn et al. 2013; Davies & Miglio 2016).
