Height-dependent Phase Shifts of Wave Pulses in the Lower Solar Atmosphere Measured with S unrise iii

Andreas Lagg, H. N. Smitha, Sami K. Solanki, Tino L. Riethmüller et autres

Abstract We report on the measurement of the height-dependent time shifts of wave pulses in the lower solar atmosphere from high-resolution spectropolarimetric observations obtained with the SUSI instrument on board the S unrise iii balloon-borne solar observatory during its successful science flight …

Exploring if a coronal dimming event can produce coronal hole-like properties

Adriana De-Sassi, Louise Harra, Krzysztof Barczyński, David H. Brooks et autres

Context . Coronal dimmings, or transient coronal holes, are manifested as a sudden reduction in extreme ultraviolet (EUV) and X-ray emission, often following solar eruptions. Aims . We investigate whether a dimming event can produce coronal hole-like plasma characteristics in the initially …

Exploring if a coronal dimming event can produce coronal hole-like properties

Adriana De-Sassi, Louise Harra, Krzysztof Barczyński, David H. Brooks et autres

Coronal dimmings, or transient coronal holes, are manifested as a sudden reduction in extreme ultraviolet (EUV) and X-ray emission, often following solar eruptions. We investigate whether a dimming event can produce coronal hole-like plasma characteristics by comparing imaging and spectroscopic observations from …

Three-dimensional Analysis of a C-class Flare Observed with Sunrise III/SCIP

C. Quintero Noda, F. Ferrente, S. K. Solanki, Yukio Katsukawa et autres

Abstract Deciphering the physical properties of flares is crucial for understanding the nature of one of the most energetic events on the Sun. We analyze high spatial and spectral resolution observations of a C-class flare, focusing on a complex light bridge in …

We report on the measurement of the height-dependent time shifts of wave pulses in the lower solar atmosphere from high-resolution spectro-polarimetric observations obtained with the SUSI instrument on board the SUNRISE III balloon-borne solar observatory during its successful science flight in July …

Solar Flare Ribbons Structured by Uncombed Chromospheric Loops

L. P. Chitta, E. R. Priest, D. Orozco Suárez, A. L. Siu-Tapia et autres

Abstract A part of the magnetic energy released during a flare is transported to the lower atmosphere. High-resolution observations show that flare ribbons, sites of energy deposition at the footpoints of flaring loops that appear bright in the chromosphere and transition region, …

Magnetic structure of coronal dark halos

J. D. Nölke, S. K. Solanki, J. Hirzberger, Hardi Peter et autres

Context. At low coronal temperatures around or below 1 MK distinct areas in the surroundings of active regions (ARs) show emission at a level significantly below the emission coming from the quiet Sun (QS). These areas are referred to as dark halos, …

A self-consistent 3D magnetohydrodynamic model producing a solar blowout jet

Yajie Chen, Hardi Peter, Damien Przybylski, L. P. Chitta et autres

Context. Solar blowout jets are a distinct subclass of ubiquitous extreme-ultraviolet (EUV) and X-ray coronal jets. Aims. Most existing models of blowout jets prescribe initial magnetic-field configurations and apply ad hoc changes in the photosphere to trigger the jets. In contrast, we …

A magnetic avalanche as the central engine powering a solar flare

L. P. Chitta, David I. Pontin, Eric R. Priest, David Berghmans et autres

Solar flares are the most powerful, magnetically driven, explosions in the heliosphere. The nature of magnetic energy release in the solar corona that heats the plasma and accelerates particles in a flare, however, remains poorly understood. Here, we report highresolution coronal observations …
