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.

CARMENES 光度测量项目 (CPP) 是卡拉阿尔托 CARMENES 径向速度调查的后续观测活动，使用我们在西班牙、德克萨斯和南非的自己的望远镜。一方面，我们建议对 CARMENES 巡天的径向速度变量进行密集且准同步的光度测量，以评估恒星活动；这些信息对于帮助区分行星的径向速度信号和活动信号的误报至关重要。另一方面，我们将在根据 CARMENES 径向速度测量预测的凌日窗口期间搜索凌日。这将排除凌日现象或导致凌日探测，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。
