摘要:

我们提出了一个社区为主导的评估太阳系的调查与美国宇航局的下一代太空望远镜,宽视场红外巡天望远镜(WFIRST)。WFIRST将提供0.43-2.0 $μ$ m的成像、光谱和日冕照相能力,并将成为JWST的潜在当代和最终继任者。不规则卫星和小型天体的调查是WFIRST将凭借其0.28度$^2$视场宽视场仪器(WFI)脱颖而出的地方。WFIRST的潜在突破性发现可能包括探测在内奥尔特云中轨道运行的第一个小天体,识别更多的地球特洛伊小行星,以及发现和描述类似于Ida/Dactyl的小行星双星系统。对小行星,巨行星卫星,特洛伊小行星,半人马座,柯伊伯带天体和彗星的额外调查。讨论了天体物理学资产在太阳系科学中的先前用途以及WFIRST、LSST、JWST和拟议的近地天体摄像机任务之间的协同作用。我们还提出了实施移动目标跟踪的情况下,一个功能,将受益于遗产的JWST,使更广泛的太阳系观测。

英文摘要:

We present a community-led assessment of the solar system investigations achievable with NASA's next-generation space telescope, the Wide Field InfraRed Survey Telescope (WFIRST). WFIRST will provide imaging, spectroscopic, and coronagraphic capabilities from 0.43-2.0 $μ$m and will be a potential contemporary and eventual successor to JWST. Surveys of irregular satellites and minor bodies are where WFIRST will excel with its 0.28 deg$^2$ field of view Wide Field Instrument (WFI). Potential ground-breaking discoveries from WFIRST could include detection of the first minor bodies orbiting in the Inner Oort Cloud, identification of additional Earth Trojan asteroids, and the discovery and characterization of asteroid binary systems similar to Ida/Dactyl. Additional investigations into asteroids, giant planet satellites, Trojan asteroids, Centaurs, Kuiper Belt Objects, and comets are presented. Previous use of astrophysics assets for solar system science and synergies between WFIRST, LSST, JWST, and the proposed NEOCam mission are discussed. We also present the case for implementation of moving target tracking, a feature that will benefit from the heritage of JWST and enable a broader range of solar system observations.
