Expectations from a Microlensing Search for Planets
The statistical distribution of the masses of planets about stars between the Sun and the center of the galaxy is constrained to within a factor of three by an intensive search for planets during microlensing events. Projected separations in terms of the lens Einstein ring radius yield a rough estimate of the distribution of planetary semimajor axes with planetary mass. The search consists of f...
متن کاملPLANET II: A Microlensing and Transit Search for Extrasolar Planets
Due to their extremely small luminosity compared to the stars they orbit, planets outside our own Solar System are extraordinarily difficult to detect directly in optical light. Careful photometric monitoring of distant stars, however, can reveal the presence of exoplanets via the microlensing or eclipsing effects they induce. The international PLANET collaboration is performing such monitoring...
متن کاملMicrolensing search for extrasolar planets: observational strategy, discoveries and implications
Microlensing has proven to be a valuable tool to search for extrasolar planets of Jovianto Super-Earth-mass planets at orbits of a few AU. Since planetary signals are of very short duration, an intense and continuous monitoring is required. This is achieved by groundbased networks of telescopes (PLANET/RoboNET, μFUN) following up targets, which are identified as microlensing events by single de...
متن کاملMicrolensing Searches for Extrasolar Planets
I review results from, and future prospects for, microlensing searches for extrasolar planets. Analyses of well-sampled microlensing light curves by several collaborations have demonstrated that current searches are sensitive to ∼> MJ planets with few AU separations from M-dwarfs in the Galactic bulge. To date, however, no unambiguous planetary detections have been made. Detailed analysis has s...
متن کاملDetecting Planets through Microlensing
More than 100 microlensing events have been detected during the last 4 years, most of them towards the Galactic Bulge. Since the line of sight towards the Bulge passes through the disk and the Bulge itself, the known stars towards the Bulge play a dominant role as gravitational lenses. If these stars have planets around them, then the signature of the planets can be seen as sharp, extra peaks o...
