Seven white dwarfs with circumstellar gas discs I: white dwarf parameters and accreted planetary abundances
L. K. Rogers, A. Bonsor, S. Xu +9
Observations of planetary material polluting the atmospheres of white dwarfs are an important probe of the bulk composition of exoplanetary material. Medium- and high-resolution op…
Spectrophotometric analysis of magnetic white dwarf II: Helium-rich compositions
François Hardy, Patrick Dufour, Stefan Jordan
We present an analysis of all single white dwarf stars known to exhibit spectroscopic signatures of neutral helium line splitting due to the presence of a strong magnetic field. Us…
Spectrophotometric analysis of magnetic white dwarf I: Hydrogen-rich compositions
François Hardy, Patrick Dufour, Stefan Jordan
We present an homogeneous analysis of all DA stars labeled as magnetic in the Montreal White Dwarf Database (MWDD). Our sample is restricted to almost all known magnetic white dwar…
