The most common observable evidence of a remnant planetary system is pollution of the spectrum of a white dwarf with metal absorption lines. 27–50% of white dwarfs show a spectrum polluted with metals, [153] but these heavy elements settle out in the atmosphere of white dwarfs colder than 20 000 K.
The common Proto-Germanic form is generally reconstructed as *dwergaz. [1] [3] ... Dwarf names in Eddic sources include Fullangr ... "Snow White and the Seven Dwarfs".

Dwarfism is a condition of people and animals marked by unusually small size or short stature. [1] In humans, it is sometimes defined as an adult height of less than 147 centimetres (4 ft 10 in), regardless of sex; the average adult height among people with dwarfism is 120 centimetres (4 ft).
