摘要
行星成图仪(PFI)项目旨在为超越即将到来的极大望远镜这一代地基光学天文学提供强有力的科学愿景。我们论证指出，为了揭示行星形成过程中涉及的物理过程，必须在角分辨率成像能力上取得突破。PFI将被优化以提供所有恒星中心半径上、年龄范围从0.1到约100 Myr的原行星种群的完整普查。在这一年龄期间，行星系统经历剧烈变化，行星系统的最终架构得以确定。我们的目标是在物质聚集的自然空间尺度，即形成中行星的“希尔球”上研究行星的诞生，并通过测量其质量和物理性质来表征原行星核。我们的科学工作组研究了这些年轻原行星的观测特征以及可能改变系统架构的迁移机制。我们模拟了行星在星盘中留下的印记，并研究了PFI如何能彻底改变从系外行星到河外天文学的多个领域。在本文中，我们概述了PFI的关键科学驱动因素，并讨论了将指导技术选择、台址选择以及潜在科学/技术权衡的要求。
