The Atacama Large Millimetre Array (ALMA) is a major new instrument for Astronomy at mm and sub-mm wavelengths. During 2017 the first regular solar observations with ALMA opened up a new view of the Sun at those wavelengths. Our group has obtained observing time with ALMA to study the solar atmosphere (e.g. filaments, prominences, active region moss) and will continue to seek more observing time to study the Sun around its minimum activity. These observations will be widely supported by a range of ground-based and space-based instruments, bringing a comprehensive coverage from the extreme-ultraviolet to the radio domains via optical and infrared parts of the spectrum. The student will carry out the analysis and interpretation of ALMA and other observations, and use them to advance our understanding of the conditions within the solar plasma and of processes associated with heating and cooling of fine-scale structures. He will also contribute to applications for further observing time on ALMA and other UK facilities. As the work progresses and detailed physical questions emerge, data analysis and interpretation will eventually be supplemented by radiation transfer modelling.

阿塔卡马大型毫米阵列（阿尔马）是一个主要的新的天文仪器在毫米和亚毫米波长。在2017年期间，阿尔马的第一次定期太阳观测在这些波长上开辟了太阳的新视角。我们的小组已经获得了与阿尔马一起研究太阳大气层（例如，细丝、折射率、活动区苔藓）的观测时间，并将继续寻求更多的观测时间，以研究太阳最低活动前后的情况。这些观测将得到一系列地面和空间仪器的广泛支持，通过光谱的光学和红外部分实现从极紫外到无线电领域的全面覆盖。学生将进行阿尔马和其他观测的分析和解释，并利用它们来推进我们对太阳等离子体内的条件以及与加热和冷却精细尺度结构相关的过程的理解。他还将为阿尔马和其他英国设施的进一步观测时间的申请做出贡献。随着工作的进展和详细的物理问题的出现，数据分析和解释最终将由辐射转移模型来补充。
