摘要:

由南京天文光学技术研究所与云南天文台合作研制的多波长太阳望远镜--光学和近红外太阳喷发跟踪仪(ONSET)是南京大学的一台新型多波长太阳望远镜。ONSET能够在三个波长窗口中观测太阳:He { \small I} 10830 nm,H $α$,以及3600 nm和4250 nm的白光,选择这些波长窗口是为了同时获得日冕,色球层和光球层的动力学。在10弧分的视场下,几乎可以同时获得三个波长的全圆盘或部分圆盘太阳图像。它的目的是以高空间和时间分辨率跟踪太阳喷发。这台望远镜安装在中国西南部云南省抚仙湖附近的一个新的太阳观测站。场地位于E102 N24,海拔1722米。视觉稳定,质量高。我们简要介绍了科学目标和ONSET的基本结构。文中还介绍了一些初步结果。

英文摘要:

A new multi-wavelength solar telescope, Optical and Near-infrared Solar Eruption Tracer (ONSET) of Nanjing University, was constructed, being fabricated by Nanjing Institute of Astronomical Optics & Technology and run in cooperation with Yunnan Astronomical Observatory. ONSET is able to observe the Sun in three wavelength windows: He {\small I} 10830 Å, H$α$, and white-light at 3600 Åand 4250 Å, which are selected in order to obtain the dynamics in the corona, chromosphere, and the photosphere simultaneously. Full-disk or partial-disk solar images with a field of 10 arcmin at three wavelengths can be obtained nearly simultaneously. It is designed to trace solar eruptions with high spatial and temporal resolutions. This telescope was installed at a new solar observing site near Fuxian Lake in Yunnan Province, southwest China. The site is located at E102N24, with an altitude of 1722 m. The seeing is stable and of high quality. We give a brief description of the scientific objectives and the basic structure of the ONSET. Some preliminary results are also presented.
