摘要:

PTF/M-dwarfs是一个100,000个目标的M-dwarfs行星凌日调查,是Palomar Transient Factory(PTF)合作的关键项目。该调查对所有目标恒星周围的行星半径都很敏感,并且有足够的精度达到海王星和超级地球的最佳目标。Palomar Transient Factory是一个全自动的广域观测系统,旨在系统地探索光学瞬变天空。这次调查是使用一个新的7.26平方度的相机安装在48英寸塞缪尔Oschin望远镜在帕洛玛天文台。每个9200万像素的R波段曝光包含大约3,000个可用于行星探测的M矮星。在每一个PTF观测季,PTF/M-矮星会搜寻近30,000颗M-矮星周围的海王星半径行星,约500颗M-矮星周围的海王星半径行星,以及100颗超级地球。预计在未来几年内,全面调查将涵盖10万多个目标。在Palomar 60英寸、LCOGT、Palomar 200英寸、MDM和Keck望远镜上进行测光和分光后续操作。这项调查自2009年年中开始。我们详细介绍了调查设计,调查的数据分析管道和第一年的业务表现。

英文摘要:

PTF/M-dwarfs is a 100,000-target M-dwarf planetary transit survey, a Key Project of the Palomar Transient Factory (PTF) collaboration. The survey is sensitive to Jupiter-radius planets around all of the target stars, and has sufficient precision to reach Neptunes and super-Earths for the best targets. The Palomar Transient Factory is a fully-automated, wide-field survey aimed at a systematic exploration of the optical transient sky. The survey is performed using a new 7.26 square degree camera installed on the 48 inch Samuel Oschin telescope at Palomar Observatory. Each 92-megapixel R-band exposure contains about 3,000 M-dwarfs usable for planet detection. In each PTF observational season PTF/M-dwarfs searches for Jupiter-radius planets around almost 30,000 M-dwarfs, Neptune-radius planets around approximately 500 M-dwarfs, and super-Earths around 100 targets. The full survey is expected to cover more than 100,000 targets over the next several years. Photometric and spectroscopic followup operations are performed on the Palomar 60-inch, LCOGT, Palomar 200-inch, MDM and Keck telescopes. The survey has been running since mid-2009. We detail the survey design, the survey's data analysis pipeline and the performance of the first year of operations.
