摘要
Backyard Worlds: Planet 9 公民科学项目利用广域红外巡天探测器的数据来探测具有显著运动的红外天体。在这项工作中，我们展示了通过这一努力发现的大多数 L 型和 T 型矮星候选体。对于每个候选体，我们提供了自行测量以及光学、近红外和中红外测光数据（如有）、测光光谱型和距离估计。本工作展示了三千零六个新的运动确认发现，其中 2,357 个具有 L 型测光光谱型，649 个具有 T 型测光光谱型。我们还额外展示了 80 个天体，它们根据可用测光数据可能是 L 型或 T 型矮星，但无法获得显著的自行测量。我们在这批样本中识别出 28 个天体为更高质量恒星的新共动伴星，另有 9 个源是由两颗 L 型或更晚型超冷矮星组成的候选双星系统。对候选体进行后续光谱观测将是确认光谱型和进一步表征本项目发现的天源所必需的。本工作展示了迄今为止最大的单一样本的运动确认 L 型和 T 型矮星发现，如果得到确认，将使已知的 L 型和 T 型矮星数量增加一倍以上。我们真诚感谢我们的公民科学合作者们的巨大努力，他们直接促成了本项目的成功。
