太阳喷流及相关耀斑的研究

Study of Solar Jets and Related Flares

Reetika Joshi

摘要:

太阳喷流是太阳大气中普遍存在的瞬时准直质量外流,其大小范围从小尺度的纳米喷流到几个太阳半径,嵌入太阳色球层到日冕。喷流经常伴随着太阳耀斑,这些耀斑提供了向上传播等离子体物质的力量,并可能伴随着日冕物质抛射。这些喷流可以作为一种来源,将大量的质量和能量从太阳大气层的下部输送到日冕的上部,从而加热日冕并加速太阳风。磁重联被认为是这些喷流活动背后的触发原因。论文题目是:太阳喷流和相关耀斑的研究,包括引发喷流引发的不同机制的各种案例研究、相关的大规模喷发,并提供强有力的观测证据来验证磁通量出现模型的数值实验。对太阳喷流及其磁源的研究有助于解决日冕加热问题,为现有的理论模型提供证据,并为行星际科学打开了一扇新的窗口。

英文摘要:

Solar jets are ubiquitous transient collimated mass outflows in the solar atmosphere over a wide range of sizes from small scale nanojets to a few solar radii, embedded in the solar chromosphere to solar corona. Jets are frequently accompanied by solar flares and these flares provide the force to propagate the plasma material upward and could be accompanied by coronal mass ejections. These jets could act as a source for transporting a significant mass and energy from the lower solar atmosphere to the upper coronal heights and consequently heating the solar corona and accelerating the solar wind. Magnetic reconnection is believed to be the triggering reason behind these jet activity. The thesis entitled: Study of Solar Jets and Related Flares, includes various case studies with different mechanisms to set off the jet initiation, associated large scale eruptions and mounts strong observational evidences to validate the numerical experiments for the magnetic flux emergence models. Such studies on solar jets along with their magnetic origin contribute to resolve the scandalous coronal heating problem and provide the evidences for the existing theoretical models and open a new window for the interplanetary science.
