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.

卡门测光计划(CPP)是卡拉阿尔托上的卡门径向速度测量的后续观测活动，使用的是我们在西班牙、得克萨斯和南非的望远镜。一方面，我们建议对Carmenes测量的径向速度变量进行密集和准同时的光度测量，以评估恒星的活动；这些信息对于从行星中分离径向速度信号和从活动信号中分离假阳性是至关重要的。另一方面，我们将搜索由Carmenes径向速度测量预测的凌日窗口期间的凌日。这要么排除凌日，要么导致凌日探测，这将为更详细的分析开辟道路，即确定行星密度及其大气层。
