<Erik A. Petigura> studies <exoplanet occurrence rates> using transit observations. His 2013 study with <Geoffrey W. Marcy> and <Andrew W. Howard> independently searched <Kepler space telescope> photometry for small <planets> with <orbital periods> of $5$–$50$ days.
To estimate how many <planets> the search missed, the team injected synthetic <exoplanet transit> signals into the observations and ran the detection procedure again. Correcting for this recovery rate changed the inference from a count of detected candidates to an estimate of the underlying population. Their inferred size distribution flattened below roughly twice <Earth>'s <radius>.<A Plateau in the Planet Population Below Twice the Size of Earth by Erik A.
