Particles, Plasma and Electromagnetic Waves in the Inner Heliosphere

近太阳环境下的太阳系等离子体物理学是太阳物理学中的一个重大挑战。日冕和内日球层是产生影响日球层并形成空间天气的太阳扰动的关键空间区域。新的十米波长射电观测（特别是低频阵列（LOFAR））将弥补这一差距，并将为研究内日球层的太阳现象以及空间天气的起源开辟新的机会。将结合模拟和新的观测结果研究高能电子的加速、传播和射电发射。具体来说，对LOFAR无线电数据的分析与美国宇航局帕克太阳探测器（前所未有地靠近太阳）的原位分析相结合，将提高我们对内日球层过程的理解。

The physics of the solar system plasma in the near-Sun environment presents a major challenge in solar physics. Solar corona and the inner heliosphere is the key region of space responsible for the birth of the solar disturbances that affects the heliosphere and forms the space weather.The new radio observations at decameter wavelength (notably with Low Frequency Array (LOFAR)) will bridge the gap and will open new opportunities to study the solar phenomena in the inner heliosphere as well as the progenitors of space weather. Acceleration, propagation and radio emission of energetic electrons will be studied combining the simulations and the new observations. Specifically, the analysis of LOFAR radio data in combination with in-situ NASA Parker Solar Probe close to the Sun (as never before) will improve our understanding of the processes in the inner heliosphere.
