. Draf - the star of small dimensions (1 - 0,01 of the Sun's radius) and of low luminance (from 1 to 10^-4 of the Sun's luminance) with mass M from 1 to 0,1 of solar mass. There are a lot of eruptive stars among the dwarfs. Unusual white drafs greatly differ with the usual red drafs in structure. Back .
