Relationship between period and eccentricity in the OWN sample, compared to other known spectroscopic binaries from the literature. Histograms are also shown. It is noticeable how the OWN SB1 populate the longer periods (log P > 2) and also the largest eccentricities. The continuous curve depicts the upper limit for eccentricity (Moe & Di Stefano 2017).
