论文摘要
在这项工作中，我们研究了一类最近发现的Metrewave太阳瞬变，称为弱冲动窄带静态太阳发射\ Citep [Winqses，] [] {Mondal2020}。它们的力量是安静的阳光背景的几％，其特征是它们在安静的阳光区域中非常冲动，狭窄和无处不在的存在。 \ citet {mondal2020}假设这些排放可能是纳米插曲的无线电对应物，其潜在意义值得详细的研究。在这里，我们对非常安静的时间进行了对数据的分析，并且对以前的工作进行了改进的方法。和以前一样，我们检测到许多Winqses，我们已将其用于进一步的特征。在这些数据中也观察到它们的关键特性，即它们在安静的太阳上的冲动性质和无处不在的存在。有趣的是，我们还发现某些观察到的特性与早期工作显着不同。通过证明对Winqses的常规发现，我们希望对更大的社区产生兴趣，以深入了解Winqses。
In this work we study a class of recently discovered metrewave solar transients referred to as Weak Impulsive Narrowband Quiet Sun Emission \citep[WINQSEs,][]{mondal2020}. Their strength is a few percent of the quiet Sun background and are characterised by their very impulsive, narrow-band and ubiquitous presence in quiet Sun regions. \citet{mondal2020} hypothesised that these emissions might be the radio counterparts of the nanoflares and their potential significance warrants detailed studies. Here we present an analysis of data from an extremely quiet time and with an improved methodology over the previous work. As before, we detect numerous WINQSEs, which we have used for their further characterisation. Their key properties, namely, their impulsive nature and ubiquitous presence on the quiet Sun are observed in these data as well. Interestingly, we also find some of the observed properties to differ significantly from the earlier work. With this demonstration of routine detection of WINQSEs, we hope to engender interest in the larger community to build a deeper understanding of WINQSEs.
