摘要
过去十年，像SPHERE@VLT这样的前沿行星探测仪器，通过耦合星形光学装置和极端自适应光学系统， thanks to 大型调查，发现了约20颗质量为行星的伴侣，其半长轴大于10个天文单位。直接成像是唯一能够探测行星系统外部区域的检测技术，SPHERE红外测绘寻找系外行星（SHINE）旨在于2015年至2021年研究此类年轻气体巨型行星围绕400颗年轻近距离太阳型恒星的人口统计学。在本文中，我们呈现了观测策略、数据质量以及针对完整SHINE统计样本以及snapSHINE的点源分析。两个调查都使用SPHERE@VLT仪器，结合IRDIS双带成像仪和积分域光谱仪IFS，以及角分辨差成像观测技术。所有SHINE数据（650个数据集），对应400颗恒星，包括F150调查的目标，均以一种称为PACO ASDI的高级后处理算法进行统一处理。我们对最有希望的候选伴侣进行分类和识别。与之前的早期分析SHINE F150相比，采用先进的后处理技术显著提高了1至2个 magnitudes（x3-x6）的对比度检测极限，这将允许我们对年轻气体巨型行星的径向分布施加更严格的约束。此提高灵敏度直接将SHINE定位为目前所做的最大且最深的直接成像调查。我们检测并分类了超过3500个物理源。调查第二阶段确认了另一颗亚星际伴侣（HIP 74865 B），以及几颗新获批的候选伴侣正在等待第二次观测确认。
