Abstract:
We present the detailed analysis of triple system KR Com with
different observational techniques - photometry, interferometry, and
period variation.
The use of BVR photometry of the close-contact binary KR Com, which is
the primary component of a triple system, helps us to better describe
the properties of the components. The interferometric data obtained
during the last 30 years sufficiently determine the visual orbit, but
the use of minima timings of KR Com for the study of period variation
together with the visual orbit is a novel approach in this system.
