Abstract

The free precession of white dwarf stars has been investigated and the increase of the free precession period due to elastic properties of the star matter computed. For these white dwarf models the ratio Δ between Chandler and Euler period turned out to lie between 8 and 21, depending upon central density of the white dwarf (4.9 10 5 g cm -3 to 1.15 10 9 g cm -3 )
