... Astronomers of the SAO together with an international group of scientists have proposed an explanation to the long-standing mystery of why magnetic fields are more common amongst cool white dwarf stars than amongst young and hotter ones. ... As the result magnetic white dwarfs demonstrate excess in their frequencies in the temperature range below 14000K. The authors also show that the strongly magnetic white dwarfs are of the oldest stars of the Galaxy originated from intermediate-mass relic stars. ...

... In the western literature this method is now called ``coupled dipole method" (CDM). ... Thus, a system of equations relative to the fields scattered by the elementary domains can be obtained, and summation of these fields gives the total scattering field. ... A subtle difference between both methods is in the fact that in the first method one works with the fields which excite a dipole (without the field of the dipole), whereas in the second method one uses the real fields in a given domain. ...
