In order to form a rocky, potentially habitable planet, like Earth, the planet’s building blocks must loose volatiles. White dwarfs that have accreted planetary material provide the perfect opportunity to study the volatile content of planetary building blocks. The unique behaviour of Mn and Na depending on the conditions under which volatiles are lost means that planetary material in the atmospheres of white dwarfs can tell us how planetary building blocks lost volatiles [1]. This talk will summarise some recent results regarding observations of volatiles in the atmospheres of white dwarfs, models that describe how white dwarfs accrete volatiles and evidence from white dwarfs for volatile loss both early, in the hot, inner regions of a planet-forming disc and late, when large-scale melting is induced following impacts.
