Figure 8: Eccentricity versus orbital period for a sample of 21 low-mass binary pulsars which are not in globular clusters, with the triangles denoting three recently discovered systems [341]. The solid line shows the median of the predicted relationship between orbital period and eccentricity [287]. Dashed lines show 95% the confidence limit about this relationship. The dotted line shows 2 Pb ∝ e. Figure provided by Ingrid Stairs [341] using an adaptation of the orbital period-eccentricity relationship tabulated by Fernando Camilo.
