Two Practical Methods for Coronal Intensity Determination
, 2017 Determining the relative brightness of the solar corona is one of the most critical stages in solar eclipse studies. For this purpose, images taken with different exposures and polarization angles in white-light observations are used. The composite image

Highlights of Astronomy, 1980 AbstractRecent observations from space have shown that the solar corona is spatially a very structured medium and temporally a very dynamic one. The consequent changes in the current theoretical ideas about coronal physics are reviewed. The role of the magnetic fields in shaping and heating the coronal structures is especially underlined.

Suprathermal Electron Transport and Electron Beam Formation in the Solar Corona
The Astrophysical Journal, 2023 Electron beams that are commonly observed in the corona were discovered to be associated with solar flares. These “coronal” electron beams are found ≥300 Mm above the acceleration region and have velocities ranging from 0.1 c up to 0.6 c .

Compensating Faraday depolarization by magnetic helicity in the solar corona
, 2017 A turbulent dynamo in spherical geometry with an outer corona is simulated to study the sign of magnetic helicity in the outer parts. In agreement with earlier studies, the sign in the outer corona is found to be opposite to that inside the dynamo.

Influence of projection effects on the observed differential rotation rate in the UV corona
Journal of Advanced Research, 2013 Following previous investigations by Giordano and Mancuso [1] and Mancuso and Giordano [2,3] on the differential rotation of the solar corona as obtained through the analysis of the intensity time series of the O VI 1032 Å spectral line observed by the ...

, 2009 We propose a new model for explaining the observations of more than mass proportional heating of heavy ions in the polar solar corona. We point out that a large number of small scale intermittent shock waves can be present in the solar corona.

, 2023 The X-ray emission from the Sun reveals a very dynamic hot atmosphere, the corona, which is characterized by a complex morphology and broad range of timescales of variability and spatial structuring. The solar magnetic fields play a fundamental role in the heating and structuring of the solar corona. Increasingly higher quality X-ray solar observations

Differential rotation measurement of soft X-Ray corona
, 2010 The aim of this paper is to study the latitudinal variation in the solar rotation in soft X-ray corona. The time series bins are formed on different latitude regions of the solar full disk (SFD) images that extend from 80 degree South to 80 degree North.

Advanced Healthcare Materials, EarlyView.Protein corona plays a critical role in the biological behavior of nanoparticles. This study investigates the distribution of complement proteins in soft corona and their impact on the macrophage uptake of polymer nanoparticles. It underlines the significance of soft corona investigation for understanding in vivo performance of nanomedicines.
