摘要
我们展示了詹姆斯·韦伯空间望远镜近红外成像仪和无缝光谱仪(JWST/NIRISS)上孔径掩模干涉测量(AMI)模式的性能分析。得益于自校准可观测量，AMI 可触及低至甚至优于经典衍射极限的内工作角。该模式的科学潜力已由早期释放科学(ERS) 1386 计划通过深度搜寻 HIP 65426 系外行星系统中的密近伴星得以证实。作为 ERS 1386 的一部分，我们使用同一数据集探究 NIRISS AMI 可观测量中的随机、静态与校准误差。我们将观测噪声特性和可实现对比度与理论预测进行比较。我们探究了校准误差的可能来源，并表明 HIP 65426 与 point-spread function 校准星的观测间电荷迁移差异可解释所实现的对比度曲线。最后，我们利用自校准测试证明，在充分校准下 NIRISS F380M AMI 可在 处达到 mag 的对比度水平。这些测试引出了观测规划建议，并强烈推动未来研究以制定考虑这些系统效应的复杂校准策略。这将释放 JWST/NIRISS AMI 前所未有的能力，其对显著更冷、更低质量的系外行星的灵敏度优于低对比度地基 AMI 装置，且处于 JWST 日冕仪无法触及的轨道间距。
