The Astrophysical Journal Supplement SeriesThe electron temperature of the corona is one of the key physical parameters which reflect the complexity of coronal-heating processes. L. E. Cram was the first to show that the K-coronal spectrum, produced by the scattering of the photospheric spectrum ...

Periodic Variations in Visible Light Brightness as Tracers of Fine Coronal Structures
The Astrophysical JournalThe quiescent or dynamic nature of fine-scale raylike features in the Sun corona, observed in visible light, is still an open question. Here, we show that most of the daily and hourly periodic variations in visible light brightness of the high corona (up

Progress in Photovoltaics: Research and Applications, EarlyView.This work deals with the degradation of solar modules with varying material combinations under accelerated aging conditions. By in situ moisture measurements and simulations of oxygen ingress, the consumption of stabilizing additives and polymer degradation can be correlated spatially resolved with the penetrating stressors.

Solar Stereoscopy and Tomography
Living Reviews in Solar Physics, 2011 We review stereoscopic and tomographic methods used in the solar corona, including ground-based and space-based measurements, using solar rotation or multiple spacecraft vantage points, in particular from the STEREO mission during 2007--2010 ...

Journal of Field Robotics, EarlyView.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

, 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
