The Sun at millimeter wavelengths V. Magnetohydrodynamic waves in a fibrillar structure
Maryam Saberi, Shahin Jafarzadeh, Sven Wedemeyer +4
Magnetohydrodynamic (MHD) waves, playing a crucial role in transporting energy through the solar atmosphere, manifest in various chromospheric structures. Here, we investigated MHD…
Unexpected frequency of horizontal oscillations of magnetic structures in the solar photosphere
M. Berretti, M. Stangalini, G. Verth +6
It is well known that the dominant frequency of oscillations in the solar photosphere is 3 mHz, which is the result of global resonant modes pertaining to the whole stella…
Unveiling the True Nature of Plasma Dynamics from the Reference Frame of a Super-penumbral Fibril
W. Bate, D. B. Jess, S. D. T. Grant +11
The magnetic geometry of the solar atmosphere, combined with projection effects, makes it difficult to accurately map the propagation of ubiquitous waves in fibrillar structures. T…
Sausage, kink, and fluting MHD wave modes identified in solar magnetic pores by Solar Orbiter/PHI
S. Jafarzadeh, L. A. C. Schiavo, V. Fedun +25
Solar pores are intense concentrations of magnetic flux that emerge through the Sun's photosphere. When compared to sunspots, they are much smaller in diameter and hence can be imp…
Identifying plasma fractionation processes in the chromosphere using IRIS
David M. Long, Deborah Baker, Andy S. H. To +7
The composition of the solar corona differs from that of the photosphere, with the plasma thought to fractionate in the solar chromosphere according to the First Ionisation Potenti…
Eruptive events with exceptionally bright emission in HI Ly-alpha observed by the Metis coronagraph
G. Russano, V. Andretta, Y. De Leo +29
Metis, the coronagraph on board Solar Orbiter, provides for the first time coronagraphic imaging in the ultraviolet HI Ly-alpha line and, simultaneously, in polarized visible light…
Intriguing Plasma Composition Pattern in a Solar Active Region: a Result of Non-Resonant Alfvén Waves?
