Evidence for a merger of binary white dwarfs: the case of GD 362
E. Garcia-Berro, P. Loren-Aguilar, A. G. Pedemonte +4
GD 362 is a massive white dwarf with a spectrum suggesting a H-rich atmosphere which also shows very high abundances of Ca, Mg, Fe and other metals. However, for pure H-atmospheres…
Detailed Spectroscopic and Photometric Analysis of DQ White Dwarfs
P. Dufour, P. Bergeron, G. Fontaine
We present an analysis of spectroscopic and photometric data for cool DQ white dwarfs based on improved model atmosphere calculations. In particular, we revise the atmospheric para…
Discovery of a Cool, Massive, and Metal-Rich DAZ White Dwarf
A. Gianninas, P. Dufour, P. Bergeron
We report the discovery of a new metal-rich DAZ white dwarf, GD 362. High signal-to-noise optical spectroscopy reveals the presence of spectral lines from hydrogen as well as CaI,…
