使用利物浦望远镜新的快速相机RISE更新了凌日系外行星WASP-3b的参数
Updated parameters for the transiting exoplanet WASP-3b using RISE, a new fast camera for the Liverpool Telescope
摘要：
一些第一批结果是由RISE报告的-一种安装在利物浦望远镜上的新的快速相机，主要用于获得凌日系外行星的高时间分辨率光变曲线，以用于凌日计时。提出了WASP-3的完全和部分过境，并使用蒙特卡罗马尔可夫链分析来更新发现论文中的参数。这导致行星半径为1.29^{+0.05}_{-0.12} R_J，因此密度为0.82^{+0.14}_{-0.09} p_J，与以前的结果一致。倾角为85.07^{+0.15}-0.16}度，与以前测定的值一致（但精度有显著提高）。发现中心凌日时间与发现论文中给出的星历表一致。然而，使用较长基线计算的新星历表的结果是T_c（0）= 2454605.55915 +- 0.00023 HJD和P = 1.846835 +- 0.000002天。
英文摘要：
Some of the first results are reported from RISE - a new fast camera mounted on the Liverpool Telescope primarily designed to obtain high time resolution light curves of transiting extrasolar planets for the purpose of transit timing. A full and partial transit of WASP-3 are presented, and a Monte Carlo Markov Chain analysis is used to update the parameters from the discovery paper. This results in a planetary radius of 1.29^{+0.05}_{-0.12} R_J and therefore a density of 0.82^{+0.14}_{-0.09} p_J, consistent with previous results. The inclination is 85.07^{+0.15}_{-0.16} deg, in agreement (but with a significant improvement in the precision) with the previously determined value. Central transit times are found to be consistent with the ephemeris given in the discovery paper. However, a new ephemeris calculated using the longer baseline results in T_c(0) = 2454605.55915 +- 0.00023 HJD and P = 1.846835 +- 0.000002 days.
