...A,=ft, and combining this with the second equation, x= ", y=%Hence Z Herculis consists of two components of equal size, one of which is twice as bright as the other. It is here assumed that the mutual eclipses are central, or nearly so; still I have not been able to...

...faint and very bright. To suit these intervals and magnitudes, DUNÉR finds that we must assume that Z Herculis consists of two stars of equal size, one of which is twice as bright as the other. The semimajor axis of the elliptic orbit of the stars is six times their diameter (assuming that one...
