Abstract

Carbon copies White dwarf stars are an endpoint of stellar evolution for some smaller stars. They come in two forms as a rule, with either hydrogen- or helium-rich atmospheres. The discovery of white dwarfs with atmospheres primarily composed of carbon, with little or no hydrogen or helium, is therefore unexpected. Though quite rare, this new type of star appears to represent an alternative route for stellar evolution.
