Transit of TrES-1

We present z-band photometry of three consecutive transits of the exoplanet TrES-1, with an accuracy of 0.15% and a cadence of 40s. We improve on estimates of the system...本文呈现了系外行星（exoplanet）TrES-1三次连续凌星（transit）事件的z波段测光（z-band photometry）数据，其测光精度达0.15%，观测采样间隔为40秒。本研究对该行星系统的参数估计进行了优化改进。
