狼疮Transit调查：结果和教训
The Lupus Transit Survey For Hot Jupiters: Results and Lessons
摘要：
我们提出了一个深，宽场过境调查的结果，针对热木星行星在银河系的狼疮地区进行了超过53个晚上集中在两个时代相隔一年。使用澳大利亚国立大学在赛丁泉天文台（SSO）的40英寸望远镜，调查覆盖了0.66平方米。°的靠近银道面的区域（b=11度）总共监测了110，372颗恒星（15.0<V<22.0）。用差分成像测光法测得16，134条光变曲线，测光精度σ <0.025 mag。在这些光变曲线中搜寻凌日，发现了四颗候选行星，它们显示出与凌日巨行星一致的低振幅变化。进一步的研究，包括光谱分类和径向速度测量，显示这四个中，一个是真正的行星伴星（Lupus-TR-3），两个是混合系统（Lupus-TR-1和4），一个是双星（Lupus-TR-2）。这次成功的调查结果对于优化观测策略和深入搜索凌日行星的后续程序具有指导意义，包括即将在SSO使用SkyMapper望远镜进行的调查。
英文摘要：
We present the results of a deep, wide-field transit survey targeting Hot Jupiter planets in the Lupus region of the Galactic plane conducted over 53 nights concentrated in two epochs separated by a year. Using the Australian National University 40-inch telescope at Siding Spring Observatory (SSO), the survey covered a 0.66 sq. deg. region close to the Galactic Plane (b=11 deg.) and monitored a total of 110,372 stars (15.0<V<22.0). Using difference imaging photometry, 16,134 light curves with a photometric precision of sigma<0.025 mag were obtained. These light curves were searched for transits, and four candidates were detected that displayed low-amplitude variability consistent with a transiting giant planet. Further investigations, including spectral typing and radial velocity measurements for some candidates, revealed that of the four, one is a true planetary companion (Lupus-TR-3), two are blended systems (Lupus-TR-1 and 4), and one is a binary (Lupus-TR-2). The results of this successful survey are instructive for optimizing the observational strategy and follow-up procedure for deep searches for transiting planets, including an upcoming survey using the SkyMapper telescope at SSO.
