摘要
在过去的几十年中，直接成像已证实存在距宿主恒星宽轨道（>10 au）的亚恒星伴星（系外行星或棕矮星）。为了理解它们的形成和演化机制，我们于 2015 年启动了 SPHERE 系外行星红外巡天 (SHINE)，这是一项针对年轻、邻近恒星的系统性直接成像巡天，以探索其人口统计特征。我们的目标是探测并表征年轻、邻近恒星周围雪线之外的巨行星和棕矮星种群。结合巡天完备性，我们的观测提供了约束这些年轻巨行星统计特性（出现率、质量和轨道分布、对恒星质量的依赖性）的机会。在本研究中，我们展示了观测和数据分析策略、探测候选体的排序过程，以及针对 150 颗恒星子样本的巡天性能，该子样本代表了完整的 SHINE 样本。观测于 2015 年 2 月至 2017 年 2 月以均匀方式使用专用的地基 VLT/SPHERE 仪器进行，该仪器配备 IFS 积分场光谱仪和 IRDIS 双波段成像仪，覆盖 0.9 至 2.3 m 的光谱范围。我们使用日冕、角微分和光谱微分成像技术，使本研究在行星质量区间内达到最佳探测性能。
