Coronal Loops: Observations and Modeling of Confined Plasma

open access: yesLiving Reviews in Solar Physics, 2014
Coronal loops are the building blocks of the X-ray bright solar corona. They owe their brightness to the dense confined plasma, and this review focuses on loops mostly as structures confining plasma.

Solar Coronal Loops Associated with Small-scale Mixed Polarity Surface Magnetic Fields

open access: yesAstrophysical Journal, Supplement Series, 2017
How and where are coronal loops rooted in the solar lower atmosphere? The details of the magnetic environment and its evolution at the footpoints of coronal loops are crucial to understanding the processes of mass and energy supply to the solar corona ...

Steadiness of Coronal Heating

open access: yesThe Astrophysical Journal, 2023
The EUI instrument on the Solar Orbiter spacecraft has obtained the most stable, high-resolution images of the solar corona from its orbit with a perihelion near 0.4 au.

Modelling of Solar Coronal Loops [PDF]

open access: yesHighlights of Astronomy, 1992
Modelling of coronal active regions in terms of loop structures began around 1974 (see Jordan 1975) and was stimulated by images of the corona in X-rays and the uv, obtained from rocket flights. Vaiana was a pioneer in this field (see Vaiana et al. 1973). The Skylab missions provided a fuller range of imaging and spectroscopic observations, and much of

A Statistical Study of Short-period Decayless Oscillations of Coronal Loops in an Active Region

open access: yesThe Astrophysical Journal, 2023
Coronal loop oscillations are common phenomena in the solar corona, which are often classified as decaying and decayless oscillations. Using the high-resolution observation measured by the Extreme Ultraviolet Imager (EUI) on board the Solar Orbiter, we ...

3D Solar Coronal Loop Reconstructions with Machine Learning

open access: yesThe Astrophysical Journal Letters, 2021
Abstract The magnetic field plays an essential role in the initiation and evolution of different solar phenomena in the corona. The structure and evolution of the 3D coronal magnetic field are still not very well known. A way to ascertain the 3D structure of the coronal magnetic field is by performing magnetic field extrapolations from ...

From Coronal Holes to Pulsars and Back Again: Learning the Importance of Data

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Although wanting to become an astronomer from an early age, I ended up in solar physics purely by chance, after first working in high-energy astrophysics.

Coronal global EIT waves as tools for multiple diagnostics [PDF]

open access: yes, 2007
Observations in EUV lines of the solar corona revealed large scale propagating waves generated by eruptive events able to travel across the solar disk for large distances. In the low corona, CMEs are known to generate, e.g. EIT waves which can be used to
