• HR 8257: A Three-Dimensional Orbit And Basic Properties 

      Fekel, Francis C.; Boden, Andrew F.; Tomkin, Jocelyn; Torres, Guillermo (2009-04)
      We have used interferometric and spectroscopic observations of HR 8257 to determine a three-dimensional orbit of the system. The orbit has a period of 12.21345 days and an eccentricity of 0.2895. The masses of the F0 and ...
