The occurrence rate of Earth - size (0.5 - 1.4 Earth radius) planets is constant across the temperature range of our sample at 0.51 (+0.06 / -0.05) Earth - size planets per star, but the occurrence of 1.4 - 4 Earth radius planets decreases significantly at cooler temperatures.

Over the past 15 years, many surveys have placed strong constraints on the occurrence rate of wide - orbit giants, mostly based on non-detections, but very few have tried to make a direct link with planet formation theories.
