Predictions of planets for 586 exosystems and a method for predicting planets in multi-planetary exosystems

Abstract : We have applied a model of planetary system formation in the field of a standing sound wave (the ‘SSW-Model’) to the prediction of planets in 586 multi-planetary exosystems (384 bi-planetary, 127 tri-planetary and 75 exosystems with four or more confirmed planets). We have verified our predictions using transit-like events from the NASA Threshold-Crossing Event (TCE) catalogue, finding that more than 80% of these events are included in our list of exoplanet predictions. We describe a method for predicting the periods and semi-major axes of additional planets for exosystems with two or more confirmed planets. The recently discovered planet Kepler-47 d with a period of 187.4 days is present in our predictions (176 ± 19 days), we predict in the Kepler-47 system also another planet with a period of 96.5 ± 11 days between Kepler-47 b and Kepler-47 d. Our method can significantly facilitate targeted searches for planets in exosystems, enabling the detection of many new exoplanets, including those located in the habitable zones.
