Histograms for the ejection of the terrestrial planet from the HZs of HD 20782 and HD 188015. The models are based on starting positions for the giant planet at perigee or apogee, respectively. The starting positions for the terrestrial planet given by δ = 0.5 were forwarded in 10° increments, resulting in 36 models per histogram display. The white bars correspond to models of minimum mass for the giant planet, whereas the black bars represent models with an increase in mass by a factor of 1.3. Note that the data given for event number 10 also include outliers, if existing.
