Understanding the Duration of Solar and Stellar Flares at Various Wavelengths
The Astrophysical Journal, 2023 Recent irradiance measurements from numerous heliophysics and astrophysics missions including Solar Dynamics Observatory (SDO), GOES, Kepler, TESS, Chandra, the X-ray Multi-Mirror Mission, and NICER have provided critical input into understanding the ...

Coronal loops above an Active Region - observation versus model
, 2014 We conducted a high-resolution numerical simulation of the solar corona above a stable active region. The aim is to test the field-line braiding mechanism for a sufficient coronal energy input.

, 1980 In the past few years it has been realised that loop structures are an important feature of the solar corona, Presumably, these structures outline the local magnetic field and in this thesis some theoretical aspects of solar coronal loops are considered.

Impulsively Excited Quasiperiodic Fast-propagating Waves in the Solar Corona
The Astrophysical JournalQuasiperiodic fast-propagating (QFP) waves excited by an impulsive, spatially localized velocity perturbation in a curved coronal loop are investigated with three-dimensional numerical simulations.

On the Size of Structures in the Solar Corona [PDF]
, 2006 Fine-scale structure in the corona appears not to be well resolved by current imaging instruments. Assuming this to be true offers a simple geometric explanation for several current puzzles in coronal physics, including: the apparent uniform cross ...

Recent Applications of Bayesian Methods to the Solar Corona
Frontiers in Astronomy and Space Sciences, 2022 Solar coronal seismology is based on the remote diagnostics of physical conditions in the corona of the Sun by comparison between model predictions and observations of magnetohydrodynamic wave activity.

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Modeling Solar Energetic Neutral Atoms from Solar Flares and CME-driven Shocks
The Astrophysical Journal, 2023 We examine the production of energetic neutral atoms (ENAs) in solar flares and coronal mass ejection (CME)-driven shocks and their subsequent propagation to 1 au. Time profiles and fluence spectra of solar ENAs at 1 au are computed for two scenarios: (1)
