Cold and Possibly Unbound Planets from Wide-Field Microlensing Surveys

PI和他的团队将继续使用引力微透镜技术与具有宽视场望远镜的国际天文台网络合作寻找新的系外行星。微透镜现象是一种通过背景光源的光在行星引力作用下发生弯曲而探测到非常微弱的物体的现象。调查人员将与国际专业和业余观察员网络进行观察。这项工作将通过让不同国家的研究人员参与进来，通过在统一引力透镜社区方面取得进展，与一些望远镜的业余科学家合作，以及公共宣传工作，产生广泛的影响。 PI还将在这一领域培养一名研究生。微透镜有可能探测到许多新的具有重要人口统计数据的系外行星，这些数据通常被其他技术所遗漏，例如发现与宿主星星高度分离的行星，自由浮动的行星，或者那些似乎不受任何星星引力约束的行星。

The PI and his team will continue to search for new exoplanets using gravitational microlensing techniques in collaboration with an international network of observatories with wide-field telescopes. Microlensing is a phenomenon which can be used to detect a very faint object, such as planet, through the planet's gravitational bending of light of a background source. The investigators will conduct observations with an international network of professional and amateur observers. This work will have broad impact by involving researchers in different countries, by making progress in unifying the gravitational lensing community, working with amateur scientists at some of the telescopes, and public outreach efforts. The PI will also train a graduate student in this field. Microlensing has the potential to detect many new exoplanets with important demographics that are often missed with other techniques, such as finding planets at high separation from the host star, and free-floating planets, or those which do not appear to be gravitationally bound to any star.
