At present, a large number of pulsating white dwarf (WD) stars is being
discovered either from Earth-based surveys such as the Sloan Digital Sky
Survey, or through observations from space (e.g., the Kepler mission). The
asteroseismological techniques allow us to infer details of internal chemical
stratification, the total mass, and even the stellar rotation profile. In this
paper, we first describe the basic properties of WD stars and their pulsations,
as well as the different sub-types of these variables known so far.
Subsequently, we describe some recent findings about pulsating low-mass WDs.Comment: 10 pages, 4 figures. To be published in the proceedings of the "THIRD
