First Radio Evidence for Impulsive Heating Contribution to the Quiet Solar Corona

This Letter explores the relevance of nanoflare-based models for heating the quiet Sun corona. Using meterwave data from the Murchison Widefield Array, we present the first successful detection of impulsive emissions down to flux densities of \~mSFU, about two orders of magnitude weaker than earlier attempts. These impulsive emissions have durations ≲1 s and are present throughout the quiet solar corona. The fractional time occupancy of these impulsive emissions at a given region is ≲10\%. The histograms of these impu ...

The Long-standing Closure Crisis in Coronal Plasmas

Coronal and solar wind physics have long used plasma fluid models to motivate physical explanations of observations; the hypothesized model is introduced into a fluid simulation to see if observations are reproduced. This procedure is called Verification of Mechanism (VoM) modeling; it is contingent on the self consistency of the closure that made the simulation possible. Inner corona VoMs typically assume weak gradient Spitzer-Braginskii closures. Four prominent coronal VoMs in place for decades are shown to contradict t ...

On the Fast Solar Wind Heating and Acceleration Processes: A Statistical Study Based on the UVCS Survey Data

The UltraViolet Coronagraph Spectrometer (UVCS) on board the SOlar and Heliospheric Observatory has almost continuously observed, throughout the whole solar cycle 23, the UV solar corona. This work addresses the first-ever statistical analysis of the daily UVCS observations, performed in the O VI channel, of the northern polar coronal hole, between 1.5 and 3 R _☉, during the period of low solar activity from 1996 April to 1997 December. The study is based on the investigation, at different heights, of the corr ...
