The polluted atmospheres of cool white dwarfs and the magnetic field connection

We present an analysis of X-Shooter spectra of the polluted hydrogen-rich white dwarfs (DAZ) NLTT 888 and NLTT 53908. The spectra of NLTT 53908 show strong, Zeeman-split calcium lines (Ca II H&K and Ca I?4226) and the star appears to be a close relative of the polluted magnetic white dwarf (DAZH...
