摘要:

根据系外行星低振幅(0.005 - 0.02星等)绕母恒星凌日的精确时间,应该可以推断系统中存在其他行星体,直到类似地球的质量。我们描述的设计和建设的上升,一个快速读出帧传输相机的利物浦望远镜设计进行这项实验。我们的调试测试的结果进行了说明,以及必要的数据处理程序。我们提出的光变曲线的两个对象,显示所需的时间和光度精度可以获得提供自动引导是用来保持目标在同一个探测器像素的整个(通常为4小时)观察运行。

英文摘要:

By the precise timing of the low amplitude (0.005 - 0.02 magnitude) transits of exoplanets around their parent star it should be possible to infer the presence of other planetary bodies in the system down to Earth-like masses. We describe the design and construction of RISE, a fast-readout frame transfer camera for the Liverpool Telescope designed to carry out this experiment. The results of our commissioning tests are described as well as the data reduction procedure necessary. We present light curves of two objects, showing that the desired timing and photometric accuracy can be obtained providing that autoguiding is used to keep the target on the same detector pixel for the entire (typically 4 hour) observing run.
