标题： JASMINE: Near-Infrared Astrometry and Time Series Photometry Science

摘要： 日本天文学卫星红外探索任务（JASMINE）是由日本宇宙航空研究开发机构（JAXA）空间与航天航空科学研究所计划的一项M级科学太空任务。 JASMINE有两个主要的科学目标。 一个是通过银河系中心巡天来开展银河考古学，旨在从近红外Hw波段（1.0-1.6 $\mu$米）的盖亚级别（~25 $\mu$弧秒）的天体测量揭示银河系核心结构和形成历史。 另一个是系外行星巡天，旨在当无法观测银河系中心时，通过M矮星的近红外时序测光发现宜居带内的类地系外行星。 我们介绍了这项任务，回顾了许多科学目标，并提出了仪器概念。 JASMINE将是首个专门的近红外天体测量太空任务，利用近红外显著较低的消光效应，提供银河系中心恒星精确的天体测量信息。 通过拍摄许多短曝光图像获得精确的天体测量数据。 因此，JASMINE银河系中心巡天数据对于系外行星凌日、恒星振荡学、变星和微引力透镜研究（包括（中间质量）黑洞的发现）等研究具有重要价值。 我们强调了这些潜在科学研究的一系列内容，并描述了与其他任务的协同作用。 显示英文摘要

摘要： Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a planned M-class science space mission by the Institute of Space and Astronautical Science, the Japan Aerospace Exploration Agency. JASMINE has two main science goals. One is the Galactic archaeology with Galactic Center Survey, which aims to reveal the Milky Way's central core structure and formation history from Gaia-level (~25 $\mu$as) astrometry in the Near-Infrared (NIR) Hw-band (1.0-1.6 $\mu$m). The other is the Exoplanet Survey, which aims to discover transiting Earth-like exoplanets in the habitable zone from NIR time-series photometry of M dwarfs when the Galactic center is not accessible. We introduce the mission, review many science objectives, and present the instrument concept. JASMINE will be the first dedicated NIR astrometry space mission and provide precise astrometric information of the stars in the Galactic center, taking advantage of the significantly lower extinction in the NIR. The precise astrometry is obtained by taking many short-exposure images. Hence, the JASMINE Galactic center survey data will be valuable for studies of exoplanet transits, asteroseismology, variable stars and microlensing studies, including discovery of (intermediate mass) black holes. We highlight a swath of such potential science, and also describe synergies with other missions.
