Description
The age-metallicity relation is a fundamental observational tool for constraining the chemical evolution of the Galactic disc in time. In this work we analyse the observational properties of this relation using binary stars that evolved avoiding mass transfer episodes consisting of a main sequence star - from which we can derive the metallicities - and a white dwarf - from which we can derive the total ages of the systems. Our sample consists of 189 WD+MS common proper motion pairs (CPMPs) identified within Gaia.
