We present the analyses of two microlensing events, OGLE-2018-BLG-0567 and OGLE-2018-BLG-0962.
Description
In both events, the short-lasting anomalies were densely and continuously covered by two high-cadence surveys. The light-curve modeling indicates that the anomalies are generated by source crossings over the planetary caustics induced by planetary companions to the hosts.
The estimated planet/host separation (scaled to the angular Einstein radius {theta}E) and mass ratio are (s, qx10^3^)=(1.81{+/-}0.02, 1.24{+/-}0.07) and (s, qx10^3^)=(1.25{+/-}0.03, 2.38{+/-}0.08), respectively. From Bayesian analyses, we estimate the host and planet masses as (M_h_, M_p_)=(0.25_-0.13_^+0.27^, M{odot}, 0.32_-0.17_^+0.34^, M_J_) and (M_h_, M_p_=(0.54_-0.28_^+0.33^, M{odot}, 1.34_-0.70_^+0.82^, M_J_), respectively.

These planetary systems are located at a distance of 7.06_-1.15_^+0.93^kpc for OGLE-2018-BLG-0567 and 6.50_-1.75_^+1.06^kpc for OGLE-2018-BLG-0962, suggesting that they are likely to be near the Galactic bulge. The two events prove the capability of current high-cadence surveys for finding planets through the planetary-caustic channel. We find that most published planetary-caustic planets are found in Hollywood events in which the source size strongly contributes to the anomaly cross-section relative to the size of the caustic.
