摘要
利用高对比度成像直接表征系外行星系统是整个系外行星界的优先重点之一。由于探测和表征类地系外行星孪生体需要大型空间任务，发展系外行星直接成像的技术与工艺是界内的驱动焦点。JWST将首次在超过5m的中红外波长直接观测太阳系外行星，提供揭示更精确化学丰度和大气条件的详细光谱，并对宽轨道间距的太阳系冰巨星行星类似体敏感，这是一个全新的系外行星类别。然而，为在任务寿命期内最大化科学产出，需要尽可能早地精细理解JWST的仪器性能。在本文中，我们描述了我们的55小时早期释放科学计划，该计划将利用全部四台JWST仪器将行星质量伴星的表征扩展到15m，并以空前灵敏度在中红外对星周盘成像。我们的计划还将评估天文台在预期常用于系外行星直接成像与光谱学的关键模式中的表现，优化数据校准与处理，并生成代表性数据集，使广泛用户群能在未来周期中有效规划通用观测计划。
