A photometric research on the eclipsing binary RU UMi.
Abstract
A series of photoelectric observations of the eclipsing binary RU UMi, made in 1972 with a yellow filter at the Astronomical Observatory of Torino, is presented. The lightcurve shows perturbations and some features not previously found. An interpretation was attempted by means of the method of Russell and Merrill. The elements found suggest that RU UMi is probably a contact system, with presence of gas streams. No period variation has been detected.
