作为NASA EPOXI机遇号使命的一部分，我们观测了七个已知的凌日系外行星系统，以构建具有极高相位覆盖率和精度的时间序列测光。在这里，我们提出了四个“热木星系统”与近太阳恒星的结果-HAT-P-4，TrES-3，TrES-2和WASP-3。我们观测了10次HAT-P-4凌日，估计行星半径Rp = 1.332 ± 0.052 RJup，恒星半径R_（max）= 1.602 ± 0.061 R_（max），倾角i = 89.67 ± 0.30 °，从第一次到第四次接触的凌日持续时间τ = 255.6 ± 1.9分钟。对于TrES-3，我们观察到7次凌日，并发现Rp = 1.320 ± 0.057 RJup，R τ = 0.817 ± 0.022 RJup，i = 81.99 ± 0.30 deg，τ = 81.9 ± 1.1 min。我们还注意到TrES-3光变曲线的长期变化，这可能是由于星星斑点。我们观测了TrES-2的9次凌日，得到Rp = 1.169 ± 0.034 RJup，R_（max）= 0.940 ± 0.026 RJup，i = 84.15 ± 0.16 deg，τ = 107.3 ± 1.1 min。最后，我们观测到WASP-3的8次凌日，发现Rp = 1.385 ± 0.060 RJup，R τ = 1.354 ± 0.056 RJup，i = 84.22 ± 0.81 deg，τ = 167.3 ± 1.3 min。我们提出了改进的轨道周期和过境时间为每个目标。我们的状态95%的置信度上限的二次日食深度在我们的宽带可见光带宽为中心的650 nm。HAT-P-4、TrES-3、TrES-2和WASP-3的这些限度分别为0.073%、0.062%、0.16%和0.11%。我们结合联合收割机的TrES-3二次日食的信息与现有的公布的数据，并确认大气可能没有逆温。
As part of the NASA EPOXI Mission of Opportunity, we observed seven known transiting extrasolar planet systems in order to construct time series photometry of extremely high phase coverage and precision. Here we present the results for four “hot-Jupiter systems” with near-solar stars—HAT-P-4, TrES-3, TrES-2, and WASP-3. We observe 10 transits of HAT-P-4, estimating the planet radius Rp = 1.332 ± 0.052 RJup, the stellar radius R⋆ = 1.602 ± 0.061 R☉, the inclination i = 89.67 ± 0.30 deg, and the transit duration from first to fourth contact τ = 255.6 ± 1.9 minutes. For TrES-3, we observe seven transits and find Rp = 1.320 ± 0.057 RJup, R⋆ = 0.817 ± 0.022 R☉, i = 81.99 ± 0.30 deg, and τ = 81.9 ± 1.1 minutes. We also note a long-term variability in the TrES-3 light curve, which may be due to star spots. We observe nine transits of TrES-2 and find Rp = 1.169 ± 0.034 RJup, R⋆ = 0.940 ± 0.026 R☉, i = 84.15 ± 0.16 deg, and τ = 107.3 ± 1.1 minutes. Finally, we observe eight transits of WASP-3, finding Rp = 1.385 ± 0.060 RJup, R⋆ = 1.354 ± 0.056 R☉, i = 84.22 ± 0.81 deg, and τ = 167.3 ± 1.3 minutes. We present refined orbital periods and times of transit for each target. We state 95% confidence upper limits on the secondary eclipse depths in our broadband visible bandpass centered on 650 nm. These limits are 0.073% for HAT-P-4, 0.062% for TrES-3, 0.16% for TrES-2, and 0.11% for WASP-3. We combine the TrES-3 secondary eclipse information with the existing published data and confirm that the atmosphere likely does not have a temperature inversion.
