色球和日珥磁力仪

The chromosphere and prominence magnetometer

Alfred G. de Wijn, Christian Bethge, Steven Tomczyk, Scott McIntosh

摘要:

色球和日珥磁力仪(ChroMag)的目标是通过对整个太阳盘的成像光谱偏振测量来量化太阳色球和日珥的相互交织的动力学和磁性。色球磁性和动力学的图像正在迅速发展,迫切需要在日光层系统的真实下边界对色球矢量磁场测量进行突破性观测。ChroMag将提供测量数据,使科学家能够研究和更好地了解太阳大气层的能量学、磁场是如何形成的、能量如何储存在大气层的磁场结构中,以及在耀斑和日冕物质抛射等空间天气事件期间能量是如何释放的。ChroMag计划的一个组成部分是致力于开发和提供社区访问“反演”工具,这些工具是对测量结果进行困难解释所必需的,并推导出等离子体的磁流体动力学参数。像ChroMag这样的仪器的测量为太阳动力学天文台(SDO)和界面区域成像光谱仪(IRIS)以及未来先进技术太阳望远镜(ATST)等地面天文台提供了关键的物理背景。

英文摘要:

The Chromosphere and Prominence Magnetometer (ChroMag) is conceived with the goal of quantifying the intertwined dynamics and magnetism of the solar chromosphere and in prominences through imaging spectro-polarimetry of the full solar disk. The picture of chromospheric magnetism and dynamics is rapidly developing, and a pressing need exists for breakthrough observations of chromospheric vector magnetic field measurements at the true lower boundary of the heliospheric system. ChroMag will provide measurements that will enable scientists to study and better understand the energetics of the solar atmosphere, how prominences are formed, how energy is stored in the magnetic field structure of the atmosphere and how it is released during space weather events like flares and coronal mass ejections. An integral part of the ChroMag program is a commitment to develop and provide community access to the "inversion" tools necessary for the difficult interpretation of the measurements and derive the magneto-hydrodynamic parameters of the plasma. Measurements of an instrument like ChroMag provide critical physical context for the Solar Dynamics Observatory (SDO) and Interface Region Imaging Spectrograph (IRIS) as well as ground-based observatories such as the future Advanced Technology Solar Telescope (ATST).
