| contents | White dwarf stars are the most common final stage of stellar evolution. Since the serendipitous discovery of the first white dwarf by William Herschel and the first physical models by Subrahmanyan Chandrasekhar and Arthur Eddington, there have been a lot of advances in the field fueled by new observational data. With new astrometric measurements enabling us to identify hundreds of thousands of white dwarf candidates, and spectroscopic surveys revealing a plethora of chemical elements in white dwarf atmospheres pointing at spectral evolution and interaction with planetary bodies, there is a lot we can learn from the characterization of observed white dwarfs. Here we provide an observational overview of white dwarf stars, describing how they are identified and characterized, and the main properties of the observed population. |
