论文摘要
暴力太阳喷发通常伴随着相对论的带电颗粒的光束。在太阳背景下，它们被称为SPE（太阳粒子事件），并已知会产生特征性的扫描频率无线电爆发。由于它们的电离潜力，这种光束会影响大气化学和宜居性。无线电观察结果在恒星耀斑之间提供了至关重要的隔离剂，并且不会产生粒子梁。在这里，我使用太阳经验数据和半定量理论估计来评估检测相关无线电爆发的可行性。我的主要结论是，对现有低频（$ν\ Lessim 10^2 \，{\ rm MHz} $）数据集的第二次频率无线电爆发的专门搜索在技术上具有挑战性，而在技术上具有挑战性，可能会证明阳光般的星星中的高能颗粒。
Violent solar eruptions are often accompanied by relativistic beams of charged particles. In the solar context, they are referred to as SPEs (Solar Particle Events) and are known to generate a characteristic swept-frequency radio burst. Due to their ionizing potential, such beams influence atmospheric chemistry and habitability. Radio observations provide a crucial discriminant between stellar flares that do and do not generate particle beams. Here I use solar empirical data and semi-quantitative theoretical estimates to gauge the feasibility of detecting the associated radio bursts. My principal conclusion is that a dedicated search for swept frequency radio bursts on second-timescales in existing low-frequency ($ν\lesssim 10^2\,{\rm MHz}$) datasets, while technically challenging, will likely evidence high energy particles beams in Sun-like stars.
