SDSS J142625.71+575218.3: The First Pulsating White Dwarf with a Large Detectable Magnetic Field
P. Dufour, G. Fontaine, J. Liebert +2
We report the discovery of a strong magnetic field in the unique pulsating carbon-atmosphere white dwarf SDSS J142625.71+575218.3. From spectra gathered at the MMT and Keck telesco…
SDSS J142625.71+575218.3, a Prototype for a New Class of Variable White Dwarf
M. H. Montgomery, Kurtis A. Williams, D. E. Winget +3
We present the results of a search for pulsations in six of the recently discovered carbon-atmosphere white dwarf ("hot DQ") stars. Based on our theoretical calculations, the star…
Might Carbon-Atmosphere White Dwarfs Harbour a New Type of Pulsating Star?
G. Fontaine, P. Brassard, P. Dufour
In the light of the recent and unexpected discovery of a brand new type of white dwarfs, those with carbon-dominated atmospheres, we examine the asteroseismological potential of su…
Rare White dwarf stars with carbon atmospheres
P. Dufour, James Liebert, G. Fontaine +1
White dwarfs represent the endpoint of stellar evolution for stars with initial masses between approximately 0.07 msun and 8-10 msun, where msun is the mass of the Sun (more massiv…
