The CARMENES Photometry Project (CPP)

CARMENES测光项目（CPP）是Calar Alto上CARMENES径向速度测量的后续观测活动，使用我们在西班牙，德克萨斯州和南非的望远镜。一方面，我们建议对CARMENES巡天的径向速度变量进行密集的准同步光度测量，以评估恒星的活动；这些信息对于帮助从行星中分离径向速度信号和从活动信号中分离假阳性信号至关重要。另一方面，我们将在由CARMENES径向速度测量预测的凌日窗口期间寻找凌日。这要么会排除凌日现象，要么会导致凌日现象的发现，这将为更详细的分析开辟道路，即确定行星密度及其大气。

The CARMENES Photometry Project (CPP) is a follow-up observational campaign to the CARMENES radial velocity survey on Calar Alto, using our own telescopes in Spain, Texas, and South Africa. On the one hand, we propose to carry out a dense and quasi-simultaneous photometry of radial velocity variables from the CARMENES survey in order to assess the stellar activity; this information is crucial to help separating radial velocity signals from planets and false positives from activity signals. On the other hand, we will search for transits during the transit windows predicted from the CARMENES radial velocity measurements. This will either exclude a transit or lead to a transit detection, which would then open up the path towards a much more detailed analysis, i.e. the determination of the planetary density and its atmosphere.
