White dwarfs represent the endpoint of stellar evolution for stars with initial masses between approximately 0.07 and 8–10, where is the mass of the Sun (more massive stars end their life as either black holes or neutron stars). The theory of stellar evolution predicts that the majority of white dwarfs have a core made of carbon and oxygen, which itself is surrounded by a helium layer and, for ∼80 per cent of known white dwarfs, by an additional hydrogen layer. All white dwarfs therefore have… Expand
Two White Dwarfs with Oxygen-Rich Atmospheres
TLDR
The detection of two white dwarfs with large photospheric oxygen abundances are reported, implying that they are bare oxygen-neon cores and that they may have descended from the most massive progenitors that avoid core collapse. Expand
Stars with Unusual Compositions: Carbon and Oxygen in Cool White Dwarfs
White dwarfs represent the end products of the evolution of all stars on the main sequence that had initial masses below ∼8M⊙. After some important mass-loss episodes in the red giant phases,Expand
An ultra-massive white dwarf with a mixed hydrogen–carbon atmosphere as a likely merger remnant
White dwarfs are dense, cooling stellar embers consisting mostly of carbon and oxygen 1 , or oxygen and neon (with a few per cent carbon) at higher initial stellar masses 2 . These stellar cores areExpand
Might carbon-atmosphere white dwarfs harbour a new type of pulsating star?
Aims. In the light of the recent and unexpected discovery of a new type of white dwarfs, those with carbon-dominated atmospheres, we examine the asteroseismological potential of such stars. TheExpand
Evolutionary and pulsational properties of white dwarf stars
White dwarf stars are the final evolutionary stage of the vast majority of stars, including our Sun. Since the coolest white dwarfs are very old objects, the present population of white dwarfsExpand
Latest generation white dwarf cooling models : theory and applications
White dwarfs are the most common stellar evolutionary end-point. Moreover, they can be considered as reliable cosmic clocks to infer the age of a wide variety of stellar populations, includingExpand
New evolutionary sequences for hot h-deficient white dwarfs on the basis of a full account of progenitor evolution
We present full evolutionary calculations appropriate for the study of hot hydrogen-deficient DO white dwarfs, PG 1159 stars, and DB white dwarfs. White dwarf sequences are computed for a wide rangeExpand

Abstract This paper is focused on the transition phase between central stars and white dwarfs, i.e. objects in the effective temperature range 100 000 – 200 000 K. We confine our review toExpand
Atmospheric parameters and carbon abundance for hot DB white dwarfs
Atmospheric parameters for hot DB (helium atmosphere) white dwarfs near effective temperatures of 25000K are extremely difficult to determine from optical spectroscopy. This is particularlyExpand
ON THE FORMATION OF HOT DQ WHITE DWARFS
We present the first full evolutionary calculations aimed at exploring the origin of hot DQ white dwarfs. These calculations consistently cover the whole evolution from the born-again stage to theExpand

Context. DQ white dwarfs show atomic or molecular carbon features in their spectra. The atmosphere consists of helium and the carbon is believed to be dredged-up to the surface by the deepeningExpand
