Age and metallicity of low-mass galaxies: From their centres to their stellar halos

Aims. In this work we aim to analyse the metallicity and the ages of the stellar halos of low-mass galaxies (M* ≲ 1010 M⊙) to better understand their formation history. Methods. We use a sample of 17 simulated central low-mass galaxies from the Auriga project with a stellar mass range from ∼3 × 108 ...
