Fleeting Small-scale Surface Magnetic Fields Build the Quiet-Sun Corona
The Astrophysical Journal Letters, 2023 Arch-like loop structures filled with million Kelvin hot plasma form the building blocks of the quiet-Sun corona. Both high-resolution observations and magnetoconvection simulations show the ubiquitous presence of magnetic fields on the solar surface on ...

An AB Initio Approach to Solar Coronal Loops [PDF]
The Astrophysical Journal, 2005 Data from recent numerical simulations of the solar corona and transition region are analysed and the magnetic field connection between the low corona and the photosphere is found to be close to that of a potential field. The fieldline to fieldline displacements follow a power law distribution with typical displacements of just a few Mm.

The Astrophysical Journal, 2022 A challenge in characterizing active region (AR) coronal heating is in separating transient (bursty) loop heating from the diffuse background (steady) heating.

Commission 10: Solar Activity [PDF]
, 2007 Commission 10 aims at the study of various forms of solar activity, including networks, plages, pores, spots, fibrils, surges, jets, filaments/prominences, coronal loops, flares, coronal mass ejections (CMEs), solar cycle, microflares, nanoflares ...

On the Nature of the Three-part Structure of Solar Coronal Mass Ejections
The Astrophysical Journal, 2022 Coronal mass ejections (CMEs) result from eruptions of magnetic flux ropes (MFRs) and can possess a three-part structure in white-light coronagraphs, including a bright front, dark cavity, and bright core.

The Equilibrium of Coronal Loops Near Separatrices
The Astrophysical Journal, 2023 We present numerical models from the field-aligned HYDrodynamics and RADiation code (HYDRAD) of a highly asymmetric closed coronal loop with near-singular expansion factor.

Coronal Loops with Different Metallicities and Generalized RTV Scaling Laws
The Astrophysical Journal, 2023 Stellar metallicity is a critical factor to characterize the stellar coronae because it directly affects the radiative energy loss from the atmosphere.

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.

, 2014 Aims. We construct a new analytical model of a solar coronal loop that is embedded in a gravitationally stratified and magnetically confined atmosphere. On the basis of this analytical model, we devise a numerical model of solar coronal loops.
