Coronal Condensations Caused by Magnetic Reconnection between Solar Coronal Loops [PDF]
The Astrophysical Journal Letters, 2018 AbstractEmployingSolar Dynamics Observatory/Atmospheric Imaging Assembly (AIA) multi-wavelength images, we report the coronal condensation during the magnetic reconnection (MR) between a system of open and closed coronal loops. Higher-lying magnetically open structures, observed in AIA 171 Å images above the solar limb, move downward and interact with ...

3D Reconstruction of Coronal Loops by the Principal Component Analysis [PDF]
Entropy, 2013 Knowing the three dimensional structure of plasma filaments in the uppermost part of the solar atmosphere, known as coronal loops, and especially their length, is an important parameter in the wave-based diagnostics of this part of the Sun.

Self-organized braiding in solar coronal loops [PDF]
Journal of Plasma Physics, 2015 AbstractIn this paper, we investigate the evolution of braided solar coronal loops. We assume that coronal loops consist of several internal strands which twist and braid about each other. Reconnection between the strands leads to small flares and heating of the loop to x-ray temperatures.

Reduced Thermal Conduction in Solar Coronal Loops
The Astrophysical JournalThermal conduction plays an important role in the energy balance of the solar coronal plasma. In this paper, we present a new method for deriving observational constraints on the density–temperature relationship for coronal loops from the differential ...

Radiation-Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System. [PDF]
Adv MaterA novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

Acoustic response to transverse oscillations in a solar coronal loop [PDF]
Astronomy & Astrophysics, 2021 Context. Magnetohydrodynamic (MHD) waves play an important role in the dynamics and heating of the solar corona. Their investigation also reveals information about the local conditions. Transverse (Alfvénic) oscillations of loops commonly occur in response to solar eruptions. It has been shown that these oscillations elicit an acoustic response through

HomoTherm: An Open-Source Approach to Modelling Heat Exchange in Humans and Other Hominins in Diverse Environments. [PDF]
Glob Chang BiolWe present ‘HomoTherm’, a human heat budget model for simulating humans and related species with diverse traits in diverse environments. It is part of the NicheMapR package for biophysical modelling and is a multi‐part extension of the ‘endoR’ function.

EUV FLICKERING OF SOLAR CORONAL LOOPS: A NEW DIAGNOSTIC OF CORONAL HEATING [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT A previous work of ours found the best agreement between EUV light curves observed in an active region core (with evidence of super-hot plasma) and those predicted from a model with a random combination of many pulse-heated strands with a power-law energy distribution.
