为了显著提升我国太阳物理研究水平、满足国家对空间天气监测和预报的重大战略需求,同时兼顾夜间时域天文学观测的需要,我们建议研制一架2.5 m大视场高分辨率望远镜(WeHiT).它将是世界上首架既做白天高分辨率太阳观测又做夜间大视场巡天观测、具有重大创新设计的特殊望远镜.它的科学目标覆盖了太阳物理、时域天文学、星系物理和太阳系外行星物理等天文领域的前沿热门课题,可为我国、特别是高校的天文学家提供一流的观测资料.特别是,作为全世界最大的轴对称太阳望远镜,具有比所有大型太阳望远镜更大的视场,可提供前所未有的太阳活动区高分辨率资料,在太阳活动区和太阳爆发现象(特别是耀斑和日冕物质抛射)的研究中有望取得突破性成果,并为我国空间天气学研究提供宝贵资料;作为中国时区的大口径、大视场望远镜,对于持续严密监控超新星、伽玛暴和大质量双黑洞等时变天文现象十分重要,将填补国际上的空白,提供在中国时区的第一手观测资料;同时在窄波段星系巡天、临近星系研究及系外行星搜索等许多领域提供宝贵的高质量资料. 

Other Abstract

We propose to construct a 2.5 m wide-field and high-resolution telescope (WeHiT). It will be the first facility in the world with a special innovative design and can conduct both high-resolution solar observations and the wide-field night sky survey. Its scientific objectives cover solar physics, time-domain astronomy, galactic astrophysics, and exoplanet science, all of which are recent hot topics in astronomy. The telescope can provide top-ranked data for Chinese astronomers. In particular, as the largest on-axis solar telescope in the world with wide-field than all large solar telescopes operating at present, it can provide unprecedented high-resolution solar data, which can help us obtain breakthrough achievements in the study of solar active regions and solar eruptions, such as solar flares and coronal mass ejections (CMEs). The data are also very useful for the study of space weather. As a large telescope in the China time-zone, the telescope is very unique in continuously monitoring short-time transient events by filling the gap in the time-zone. Furthermore, it can provide valuable high-quality data of the narrow-band extragalactic survey, nearby galaxy study and exoplanet survey. Moreover, the telescope is a top-level one which can make essential contribution to training the graduate and undergraduate students majoring in observational astronomy.
