| Popis: | For the first and second DDLES components the radii are, respectively, $${\propto}1/(M_{1}/M_{2})^{\omega}$$ and $${\propto}(M_{1}/M_{2})^{\omega}$$ . $$M_{1}$$ and $$M_{2}$$ are, respectively, the gravitational masses of the first and second DDLES components, $$M_{1}/M_{2}\geqslant 1$$ and $$\omega=0$$ , 1, 3/2. The luminosities are, respectively, $${\propto}\eta^{*}_{1}(M_{1}/M_{2})^{1/2}$$ and $${\propto}\eta^{*}_{2}/(M_{1}/M_{2})^{1/2}$$ , where $$\eta^{*}$$ is the reduced luminosity of the DDLES component. The absolute and relative evolutionary expansions of the first and second DDLES components are discrete. The distributions of the DDLES’s along the axes $$M_{1}/M_{2}$$ and $$\log(\eta^{*}_{1}/\eta^{*}_{2})$$ have, respectively, six and four peaks, the positions of which are determined by the constant steps. In all DDLES’s there are some discrete physical systems which create the discrete effects in absolute and relative evolutionary expansions, nucleosynthesis, formation of the first and second DDLES components. A general gravitational mass of any DDLES and the gravitational masses of its two components are proposed as these discrete physical systems. The DDLES’s are useful physical laboratories for studying the gravitation of stars located at a relatively small distance from each other. |
