Montsec天文台的Fabra-ROA Baker-Nunn相机：系外行星transit探测的宽视场成像设施
The Fabra-ROA Baker-Nunn Camera at Observatori Astronòmic del Montsec: a wide-field imaging facility for exoplanet transit detection
摘要：
美国史密森学会在60年代制造了一批贝克-纳恩相机（BNC），作为人造卫星的光学跟踪系统，具有最佳的光学和机械规格。其中一个安装在皇家海军研究所和观察站。我们对将安装在蒙特塞克天文台（OAdM）的望远镜进行了深入的翻新项目。因此，BNC提供了巨大FOV（4.4 $°$ x4.4 $°$）和孔径（导致V $\sim$ 20的极限幅度）的最大组合。这些技术指标以及它们的遥控和机器人性质，使该仪器能够在适当的星等范围内以高信噪比面对通过凌日技术探测系外行星的观测计划。
英文摘要：
A number of Baker-Nunn Camera (BNC) were manufactured by Smithsonian Institution during the 60s as optical tracking systems for artificial satellites with optimal optical and mechanical specifications. One of them was installed at the Real Instituto y Observatorio de la Armada (ROA). We have conducted a profound refurbishment project of the telescope to be installed at Observatori Astronòmic del Montsec (OAdM). As a result, the BNC offers the largest combination of a huge FOV (4.4$°$x4.4$°$) and aperture (leading to a limiting magnitude of V$\sim$20). These specifications, together with their remote and robotic natures, allows this instrument to face an observational program of exoplanets detection by means of transit technique with high signal-to-noise ratio in the appropiate magnitude range.
