Abstract

Radial velocity observations of V 1010 Oph obtained at Asiago from 23 spectra combined with those published by Guinan and Koch (1977) reveal a significant eccentricity (e≃0.20±0.03) with a periastron angle close to 90° at 1 σ level. This underlines the need for a new analysis of the light curve for photometric elements.
