摘要:

我们提出了新的行星候选人确定在美国宇航局开普勒第二季度公开发布的数据由志愿者从事行星猎人公民科学项目。这里提出的两个候选者通过了假阳性检查,包括检查像素偏移以限制背景食二进制的可能性。候选行星的轨道周期分别为97.46天(KIC 4552729)和284.03天(KIC 10005758),模拟的行星半径分别为5.3和3.8 R_Earth。后一颗恒星还有另外一颗已知的行星候选者,半径为5.05 R_Earth,周期为134.49,由开普勒管道探测到。这些候选者的发现说明了大规模分布的志愿者对开普勒数据库进行审查的价值,以恢复否则无法编目的候选者。

英文摘要:

We present new planet candidates identified in NASA Kepler quarter two public release data by volunteers engaged in the Planet Hunters citizen science project. The two candidates presented here survive checks for false-positives, including examination of the pixel offset to constrain the possibility of a background eclipsing binary. The orbital periods of the planet candidates are 97.46 days (KIC 4552729) and 284.03 (KIC 10005758) days and the modeled planet radii are 5.3 and 3.8 R_Earth. The latter star has an additional known planet candidate with a radius of 5.05 R_Earth and a period of 134.49 which was detected by the Kepler pipeline. The discovery of these candidates illustrates the value of massively distributed volunteer review of the Kepler database to recover candidates which were otherwise uncatalogued.
