利用分光偏振无线电成像结合Aditya-L1和PUNCH任务进行空间天气研究
Space Weather Research using Spectropolarimetric Radio Imaging Combined With Aditya-L1 and PUNCH Missions
摘要：
几十年来，低频射电观测一直被认为是空间天气观测的有力工具。射电观测对从日冕物质抛射（CME）到太阳风的各种SW相关观测都很敏感。地面无线电观测台可以在很长一段时间内收集高时间和高频谱分辨率的高灵敏度数据，这对大多数天基观测台来说仍然是一个挑战。虽然像行星际闪烁（IPS）这样的无线电技术已经很成熟，但无线电成像研究仍然具有技术挑战性。现在，随着Murchison Widefield Array（MWA）等仪器的数据和强大的无监督分析管道的融合，这种情况正在发生变化。该管道提供了前所未有的保真度和动态范围的全斯托克斯无线电图像。这将成为日冕和日光层研究的有力工具。本文介绍了日冕物质抛射等离子体和冲击波阵面磁场测量的最新进展和成就，并介绍了在太阳视场中测量日光层法拉第旋转的现状。我们设想，在未来几年，新一代无线电仪器的可用性与Aditya-L1和PUNCH任务相结合，将标志着空间天气建模和预测新时代的开始。
英文摘要：
Low-frequency radio observations have been expected to serve as a powerful tool for Space Weather (SW) observations for decades. Radio observations are sensitive to a wide range of SW-related observations ranging from emissions from coronal mass ejections (CMEs) to the solar wind. Ground-based radio observatories allow one gathering of high-sensitivity data at high time and spectral resolution for an extended period, which remains a challenge for most space-based observatories. While radio techniques like Interplanetary Scintillation (IPS) are well established, radio imaging studies have remained technically challenging. This is now changing with the confluence of data from instruments, like the Murchison Widefield Array (MWA), and robust unsupervised analysis pipelines. This pipeline delivers full Stokes radio images with unprecedented fidelity and dynamic range. This will serve as a powerful tool for coronal and heliospheric studies. We present the recent developments and achievements to measure the magnetic fields of the CME plasma and shock front at coronal heights and also share the current status of the objective to measure the heliospheric Faraday rotation towards numerous background linearly polarised radio sources with the Sun in the field of view. We envision that in the coming years, the availability of new-generation radio instruments combined with the Aditya-L1 and PUNCH mission will mark the start of a new era in Space Weather modeling and prediction.
