1998-2000 OGLE events microlensing limits
Listed in IVOA Registry (Virtual Observatory)
We analyse three years (1998-2000) of Optical Gravitational Lensing Experiment (OGLE) observations of microlensing events to place limits on the abundance of planets with a planet-to-star mass ratio q=10^-3^ at distances ~1-4AU from their host stars, i.e. 'cool Jupiters'.
Description
We fit a total of 145 events using a maximum-likelihood fit that adjusts six parameters. Each data point on the light curve allows us to exclude planets close to the two images of the source appearing on opposite sides of the Einstein ring of the lens star.
We proceed to compute detection probability maps for each event, using {Delta}{chi}^2^ threshold values of 25, 60 and 100, and combine the results from all events to place global constraints. Our selection criteria returned five candidate events for a planet with mass ratio q=10^-3^.
