摘要:

我们报告发现了一颗行星过境一个中等亮度(V = 12.00)G恒星,轨道周期为2.788491 +/-0.000025天。根据凌日光变曲线,我们确定行星的半径为Rp = 1.257 +/- 0.053 RJup。HAT-P-5 b的质量为Mp = 1.06 +/- 0.11 MJup,与之前已知的凌日系外行星的平均质量相似,密度为rho = 0.66 +/- 0.11 g cm^-3。我们发现凌日中心Tc = 2,454,241.77663 +/- 0.00022(HJD),凌日总持续时间为0.1217 +/- 0.0012天。

英文摘要:

We report the discovery of a planet transiting a moderately bright (V = 12.00) G star, with an orbital period of 2.788491 +/-0.000025 days. From the transit light curve we determine that the radius of the planet is Rp = 1.257 +/- 0.053 RJup. HAT-P-5b has a mass of Mp = 1.06 +/- 0.11 MJup, similar to the average mass of previously-known transiting exoplanets, and a density of rho = 0.66 +/- 0.11 g cm^-3 . We find that the center of transit is Tc = 2,454,241.77663 +/- 0.00022 (HJD), and the total transit duration is 0.1217 +/- 0.0012 days.
