标题： Search for gamma-ray emission from solar system bodies with Fermi-LAT

摘要： 费米伽马射线太空望远镜（FERMI-LAT）正在进行一次全天空的伽马射线巡天，范围从 30 MeV 到$>$300 GeV，其灵敏度和角分辨率前所未有。 自观测开始的最初几周内，费米已经探测到来自月球和太阳的高能伽马射线。 这种辐射是由宇宙射线与这些天体之间的相互作用产生的。 类似地，一些伽马射线发射也可以由小行星和行星与宇宙射线的相互作用产生。 在数据采集的前 6 个月里，我们针对主要行星搜索了这种辐射。 本文介绍了搜索工作的现状。 显示英文摘要

摘要： FERMI-LAT is performing an all-sky gamma-ray survey from 30 MeV to $>$300 GeV with unprecedented sensitivity and angular resolution. FERMI has detected high-energy gamma rays from the Moon and Sun since the first weeks of data taking. This emission is produced by interactions of cosmic rays with these objects. Similarly, some gamma ray emission can be produced by interactions with asteroids and planets. We have searched this emission looking major planets during the first 6 months of data taking. We present here the status of the search.
