Analysing their spectra reveals the bulk composition of the exoplanetary material that they have accreted.', 'We analyse the abundances of a wide binary system consisting of a K-dwarf and a white dwarf which has accreted planetary material. As binary pairs are chemically homogeneous, the K-dwarf is used as a proxy for the progenitor composition of the white dwarf.', 'The abundances of the K-dwarf and the planetary material polluting the atmosphere of the white dwarf are consistent with the hypothesis that exoplanetary bodies have the same refractory composition as their host stars.', 'Check out the paper for more detail, discussions and caveats', '@MarcoMarco1822 Potentially! Although planet formation is very complicated. It may help to target certain stars when looking for potential exoplanets where life as we know it could exist!', '@MarcoMarco1822 We can use observations of polluted white dwarfs to infer if there was a core/mantle or even water sometimes, however, these planets have been destroyed so this makes it hard to find life there!']",21,02,1261
