Coronal Magnetic Fields Derived with Images Acquired during the 2017 August 21 Total Solar Eclipse
The Astrophysical Journal, 2023 The coronal magnetic field, despite its overwhelming importance to the physics and dynamics of the corona, has only rarely been measured. Here, electron density maps derived from images acquired during the total solar eclipse of 2017 August 21 are ...

Alfvén Wave Connection between the Chromosphere and the Corona of the Sun: An Analytical Study
The Astrophysical Journal, 2023 Alfvén waves are closely relevant to the three outstanding problems in the solar corona: coronal heating, solar wind acceleration, and the fractionization of low first ionization potential (FIP) elements.

Characterizing the Spectral Structure of Weak Impulsive Narrowband Quiet Sun Emissions
The Astrophysical Journal, 2023 Weak Impulsive Narrowband Quiet Sun Emissions (WINQSEs) are a newly discovered class of radio emission from the solar corona. These emissions are characterized by their extremely impulsive, narrowband, and ubiquitous nature.

Micro-events in the active and quiet solar corona [PDF]
Advances in Space Research, 2003 The content of hot material in the corona is not constant. Soft X-ray and high-temperature EUV line observations show that new material, apparently heated and evaporated from the chromosphere, is frequently injected into the corona both in active and quiet regions. Active regions are found to exhibit transient brightenings, termed here microflares, due

Tracking Nonradial Outflows in Extreme Ultraviolet and White Light Solar Images
The Astrophysical Journal, 2023 Understanding the solar corona requires knowledge of its dynamics through its various layers and subsequent connectivity to the heliosphere. This requires understanding the nature of the outflows and the physical transitions through the middle corona (∼1.
