Primordial Stellar Metallicity
Absence of a Correlation between White Dwarf Planetary Accretion and
Primordial Stellar Metallicity
Over a quarter of white dwarfs have photospheric metal pollution, which is evidence for recent accretion of exoplanetary material. While a wide range of mechanisms have been proposed to account for this pollution, there are currently few observational constraints to differentiate between them. To investigate the driving mechanism, we observe …
