OGLE wide-orbit exoplanets
Listed in IVOA Registry (Virtual Observatory)
We use nearly 20yr of photometry obtained by the OGLE survey to measure the occurrence rate of wide-orbit (or ice giant) microlensing planets, i.e.,with separations from ~5a.u. to ~15a.u. and mass-ratios from 10^-4^ to 0.033.
Description
In a sample of 3112 events we find six previously known wideorbit planets and a new microlensing planet or brown dwarf OGLE-2017-BLG-0114Lb, for which close and wide orbits are possible and close orbit is preferred.
We run extensive simulations of the planet detection efficiency, robustly taking into account the finite-source effects. We find that the extrapolation of the previously measured rate of microlensing planets significantly under-predicts the number of wide-orbit planets. On average, every microlensing star hosts 1.4^+0.9^_-0.6^ ice giant planets.
