Multi-wavelength synthesis of a flux rope-trapped mini-prominence eruption and post-flare coronal rain
Samrat Sen, Alexander G. M. Pietrow, Veronika Jercic +1
Small-scale eruptive phenomena in the solar corona including miniature flux ropes and associated cool plasma condensations are not fully understood despite increasing high-resoluti…
Extreme-ultraviolet synthesis of nanojet-like ejections due to coalescing flux ropes
Samrat Sen, A. Ramada C. Sukarmadji, D. Nóbrega-Siverio +3
Detection and characterization of small-scale energetic events such as nanoflares and nanojets remain challenging owing to their short lifetimes, small spatial extent, and relative…
Role of magnetic shear distribution on the formation of eruptive flux ropes
Samrat Sen, Sushree S Nayak, Patrick Antolin
Erupting flux ropes play crucial role in powering a wide range of solar transients, including flares, jets, and coronal mass ejections. These events are driven by the release of st…
The coronal power spectrum from MHD mode conversion above sunspots
Hemanthi Miriyala, Richard J. Morton, Elena Khomenko +2
Sunspots are intense regions of magnetic flux that are rooted deep below the photosphere. It is well established that sunspots host magnetohydrodynamic waves, with numerous observa…
The Lorentz force at work: multi-phase magnetohydrodynamics throughout a flare lifespan
Wenzhi Ruan, Rony Keppens, Limei Yan +1
The hour-long, gradual phase of solar flares is well-observed across the electromagnetic spectrum, demonstrating many multi-phase aspects, where cold condensations form within the…
Transverse MHD waves as signatures of braiding-induced magnetic reconnection in coronal loops
A. Ramada. C. Sukarmadji, Patrick Antolin
A major coronal heating theory based on magnetic reconnection relies on the existence of braided magnetic field structures in the corona. In this small-angle reconnection scenario,…
