HD 165590 - a spectroscopic-visual triple system.
Abstract
IID 165590 is known to be a visual binary with a period of 20 years and extremely high orbital eccentricity. New instrumental and computer techniques are used to show that one member of the visual pair is a spectroscopic binary with a period of 0.879511 day. Key words: spectroscopic binary-visual binary-radial velocities
