| Zusammenfassung |
| Microlensing planet hunt is a unique method to probe efficiently for
frozen Super Earth orbiting the most common stars of our galaxy. It is
nicely complementing the parameter space probed by very high accuracy
radial velocity measurements and future space based detections of low mass
transiting planets. In order to maximize the planet catch, the
microlensing community is engaged in a total cooperation among the
different groups (OGLE, MicroFUN, MOA, PLANET/RoboNET) by making the real
time data available, and mutual informing/reporting about modeling
efforts. Eight planets have been published so far by combinations of the
different groups, 4 Jovian analogues, one Neptune and two Super Earth.
Given the microlensing detection efficiency, it suggests that these
Neptunes/Super Earths may be quite common. Using networks of dedicated
1-2m class telescopes, the microlensing community has entered a new phase
of planet discoveries, and will be able to provide constraints on the
abundance of frozen Super-Earths in the near future. Statistics about Mars
to Earth mass planets, extending to the habitable zone will be achieved
with space based wide field imagers (EUCLID) at the horizon 2017. |
