Dynamic formation of multi-threaded prominences in arcade configurations

V. Jercic et al.

Summary: This study reveals the importance of random localized heating in the evolution of prominences and their threaded structure. Random heating strongly influences the morphology, area, mass, minimum temperature, and average density of prominence threads. Stronger heating sources can generate condensations faster and result in larger and more massive prominences. We also detail how stochastic heating sources determine counter-streaming flows and oscillations of prominence threads.

1.5D non-LTE spectral synthesis of a 3D filament and prominence simulation

J. M. Jenkins et al.

Summary: This paper introduces a new method based on the "Lightweaver" framework, which enables non-local thermodynamic equilibrium spectral synthesis of solar filaments and prominences in three-dimensional magnetohydrodynamic simulations. By comparing the synthesized spectra with observational results, it is found that there is a good agreement between the two.

The role of asymmetries in coronal rain formation during thermal non-equilibrium cycles

Gabriel Pelouze et al.

Summary: By studying the geometric shape of periodic coronal rain events and conducting simulations, we found that the occurrence of abundant coronal rain or lack thereof in TNE cycles depends on the asymmetry of the loop and heating. The results show that asymmetric loops are less likely to produce coronal rain, while symmetric loops only produce rain when the heating is also symmetric.

Decayless longitudinal oscillations of a solar filament maintained by quasi-periodic jets

Y. W. Ni et al.

Summary: This study investigates the decayless longitudinal filament oscillations through observations and numerical simulations. It is found that these oscillations are maintained by quasi-periodic jets and the period of oscillations depends not only on the pendulum model but also on the driving period of the jets.

An approximate recipe of chromospheric radiative losses for solar flares

J. Hong et al.

Summary: The study aims to construct an approximate recipe of chromospheric radiative losses for solar flares by tabulating optically thin radiative loss, escape probability, and ionization fraction using a grid of flare models from radiative hydrodynamic simulations. The new lookup tables provided a better approximation of detailed radiative losses for flares compared to previous recipes.

Coronal Rain in Randomly Heated Arcades

Xiaohong Li et al.

Summary: In this study, a 2.5-dimensional magnetohydrodynamic simulation using the MPI-AMRVAC code is performed to investigate the formation and evolution of the coronal rain phenomenon. The simulation shows the presence of dark structures resembling rain showers, as well as bright blobs with cool cores, consistent with real observations. Statistical analysis of the rain blobs reveals continuous heating-condensation cycles and variations in EUV emissions. Compared to previous studies, the rain occurs faster and in more erratic cycles. Individual blob movement is dominantly driven by the pressure evolution in the dynamic loop system.

Resolving the solar prominence/filament paradox using the magnetic Rayleigh-Taylor instability

Jack M. Jenkins et al.

Summary: It has been discovered that prominences and filaments in the solar corona are structures formed by the interaction of the ambient magnetic field and plasma. Simulations have shown that the different appearances of these structures when projected against the solar disk or at the limb can be explained by a universal gravitational interchange process. These findings are important for predicting observations from future instruments and understanding the formation and evolution of these structures.

The influence of flux rope heating models on solar prominence formation

N. Brughmans et al.

Summary: This study investigates the influence of different heating models on the formation and morphology of solar prominences. Numerical simulations show that different heating models result in different types of condensations within the flux rope structure.

Detection of Ubiquitous Weak and Impulsive Nonthermal Emissions from the Solar Corona

Rohit Sharma et al.

Summary: The hypothesis of nanoflares suggests that weak energy releases are responsible for coronal heating. Mondal et al. recently reported weak and impulsive emissions that may be radio counterparts of nanoflares. In this study, using data from the Murchison Widefield Array, the authors detect bursts of weak impulsive emissions from the Sun and analyze their properties, including brightness temperatures, distributions, morphologies, durations, and associations with extreme-UV images.

Transition region adaptive conduction (TRAC) in multidimensional magnetohydrodynamic simulations

Yu-Hao Zhou et al.

Summary: The study aims to extend the adaptive conduction method to fully multidimensional magnetohydrodynamic settings for realistic applications in solar atmosphere simulations. Two strategies are proposed and demonstrated in 2D simulations, showing promising results in addressing the underestimated chromospheric evaporation due to poor spatial resolution in the transition region.

A Unified Model of Solar Prominence Formation

C. J. Huang et al.

Summary: The formation of solar prominences or filaments can be explained by two popular mechanisms: direct injection and evaporation-condensation models. In the direct injection model, cold plasma is ejected from the chromosphere into the corona, while in the evaporation-condensation model, cold plasma is heated and evaporated into the corona before condensing into prominences. Both mechanisms can be unified by localized heating in the chromosphere, with variations leading to either direct injection or evaporation-condensation processes.

Kink Oscillations of Coronal Loops

V. M. Nakariakov et al.

Summary: Kink oscillations of coronal loops, driven by impulsive energy releases, are one of the most studied dynamic phenomena in the solar corona. The oscillation periods increase linearly with the major radius of the loops, demonstrating that kink oscillations are natural modes of the loops. These oscillations can be in rapidly decaying or decayless regimes, depending on the parameters of the oscillating loop.

A fundamental mechanism of solar eruption initiation

Chaowei Jiang et al.

Summary: Solar eruptions can be efficiently initiated in a single bipolar configuration through photospheric shearing motion alone, without the need of any additional special topology, as shown in fully three-dimensional magnetohydrodynamic simulations. Magnetic reconnection expels the entire arcade impulsively, forming a fast-expanding twisted flux rope with a highly turbulent reconnecting region underneath. The simplicity and efficacy of this scenario argue strongly for its fundamental importance in the initiation of solar eruptions.
