讲座摘要

Low-frequency radio observation provides a unique viewing point for solar and spaceweather studies,including the inspection of solar energetic particles and the diagnostics for background plasmas. Solar radio bursts are generated from high energy particles pacing through the solar atmosphere and inner heliosphere interacting with the background plasma.The Low-frequency array (LOFAR)is a radio telescope composed of massive numbers of antennas spreading all over Europe,it is currently the largest radio telescope in the frequency range of 10-240MHz.In thistalk,I present the recent proceedings in solar and spaceweather radio observations with LOFAR's high resolution and sensitivity,including the imaging and spectroscopy of solar radio bursts, using bright quasar to perform sounding detection for the inner-heliosphere,and imaging of the quiet Sun.
