A New Generation of Cool White Dwarf Atmosphere Models. IV. Revisiting the Spectral Evolution of Cool White Dwarfs
Simon Blouin, Patrick Dufour, Christian Thibeault +1
As a result of competing physical mechanisms, the atmospheric composition of white dwarfs changes throughout their evolution, a process known as spectral evolution. Because of the…

Line Profiles of the Calcium I Resonance Line in Cool Metal-polluted White Dwarfs
S. Blouin, N. F. Allard, T. Leininger +2
Metal-polluted white dwarfs (DZ stars) are characterized by a helium-rich atmosphere contaminated by heavy elements traces originating from accreted rocky planetesimals. As a detai…

A New Generation of Cool White Dwarf Atmosphere Models. III. WD J2356209: Accretion of a Planetesimal with an Unusual Composition
S. Blouin, P. Dufour, N. F. Allard +3
WD J2356209 is a cool metal-polluted white dwarf whose visible spectrum is dominated by a strong and broad sodium feature. Although discovered nearly two decades ago, no detaile…
