Lomnicky Peak天文台的SECIS仪器
The SECIS instrument on the Lomnicky Peak Observatory
摘要:
将在斯洛伐克科学院天文研究所Lomnicky峰高海拔太阳观测台利用弗罗茨瓦夫大学天文研究所(波兰)提供的中型Lyot日冕仪和焦点后仪器SECIS对日冕的加热机制进行研究。这些数据将研究负责将日冕加热到百万开尔文温度的能量传输和释放。特别是调查将集中在太阳日冕中可能的高频MHD波的检测。本文介绍了该项目的科学背景、为Lomnicky Peak日冕观测而改进的SECIS系统的技术细节以及试验数据的检验。
英文摘要:
Heating mechanisms of the solar corona will be investigated at the high-altitude solar observatory Lomnicky Peak of the Astronomical Institute of SAS (Slovakia) using its mid-size Lyot coronagraph and post-focal instrument SECIS provided by Astronomical Institute of the University of Wroclaw (Poland). The data will be studied with respect to the energy transport and release responsible for heating the solar corona to temperatures of mega-Kelvins. In particular investigations will be focused on detection of possible high-frequency MHD waves in the solar corona. The scientific background of the project, technical details of the SECIS system modified specially for the Lomnicky Peak coronagraph, and inspection of the test data are described in the paper.
