Radial Stellar Age Gradients in 42 Local Volume Dwarf Galaxies

Abstract We present radial stellar age gradients measured from star formation histories (SFHs) fit to resolved color–magnitude diagrams (CMDs) of 42 Local Volume dwarfs (6 ≲ Log M ⋆ / M ⊙ ≲ 9), spatially divided into elliptical annuli. Ages in each annulus are quantified using τ...
