Evidence of enhanced magnetism in cool, polluted white dwarfs

Evidence of enhanced magnetism in cool, polluted white dwarfs

We report the discovery of a new, polluted, magnetic white dwarf in the Luyten survey of high-proper motion stars. High-dispersion spectra of NLTT 7547 reveal a complex heavy element line spectrum in a cool (≈5200 K) hydrogen-dominated atmosphere showing the effect of a surface averaged field of 163...
