Multi-height Identification of Sausage and Fluting Eigenmodes in a Solar Pore
Shahin Jafarzadeh, David B. Jess, Marco Stangalini +34
Magnetic pores are compact, strongly magnetised waveguides in the lower solar atmosphere and therefore provide favourable conditions for identifying magnetohydrodynamic (MHD) wave…
Magnetically Structured Oscillatory Power Along an Active-Region Transect in Near-UV Sunrise-III/SUSI Spectroscopy
Shahin Jafarzadeh, David B. Jess, Marco Stangalini +33
We present a multi-line characterisation of how oscillatory power is organised across distinct magnetic environments in an active region using seeing-free, stratospheric near-ultra…
The Influence of Opacity on Inferred MHD Wave Signatures in the Lower Solar Atmosphere
Samuel J. Skirvin, Samuel D. T. Grant, David B. Jess +8
Magnetohydrodynamic wave activity in small-scale magnetic structures, such as solar pores, provides key insights into energy transport in the lower solar atmosphere. This study pre…
Adaptive multi-line fitting for stable line-core intensity and Doppler velocity
Shahin Jafarzadeh, David B. Jess, Marco Stangalini +5
Next-generation solar spectrographs increasingly record dense wavelength windows in which tens to hundreds of spectral lines are sampled at each spatial location and time step. Thi…
Analysing the highly irregular boundaries of solar pores
T. J. Duckenfield, D. B. Jess, S. Jafarzadeh +3
Solar pores possess irregular and evolving boundaries that are often far from the ideal circular flux tubes assumed in many magnetohydrodynamic (MHD) oscillation models. To tackle…
Determining the Polarisation of a Coronal Standing Kink Oscillation Using Spectral Imaging Techniques with the Coronal Multi-channel Polarimeter (CoMP)
T. J. Duckenfield, D. B. Jess, R. J. Morton +1
Coronal oscillations offer insight into energy transport and driving in the solar atmosphere. Knowing its polarisation state helps constrain a wave's displacement and velocity ampl…
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…
Kelvin-Helmholtz instability and heating in oscillating loops perturbed by power-law transverse wave drivers
Konstantinos Karampelas, Tom Van Doorsselaere, Mingzhe Guo +2
Instabilities in oscillating loops are believed to be essential for dissipating the wave energy and heating the solar coronal plasma. Our aim is to study the development of the Kel…
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…
Influence of the Lower Atmosphere on Wave Heating and Evaporation in Solar Coronal Loops
Mingzhe Guo, Timothy Duckenfield, Tom Van Doorsselaere +3
We model a coronal loop as a three-dimensional magnetic cylinder in a realistic solar atmosphere that extends from the chromosphere to the corona. Kink oscillations, believed ubiqu…
Cut-off of transverse waves through the solar transition region
Gabriel Pelouze, Tom Van Doorsselaere, Konstantinos Karampelas +2
Context. Transverse oscillations are ubiquitously observed in the solar corona, both in coronal loops and open magnetic flux tubes. Numerical simulations suggest that their dissipa…
Probing the Density Fine Structuring of the Solar Corona with Comet Lovejoy
Giuseppe Nisticò, Gaetano Zimbardo, Silvia Perri +3
The passage of sungrazing comets in the solar corona can be a powerful tool to probe the local plasma properties. Here, we carry out a study of the striae pattern appearing in the…
The dynamics and observability of circularly polarized kink waves
N. Magyar, T. Duckenfield, T. Van Doorsselaere +1
Context. Kink waves are routinely observed in coronal loops. Resonant absorption is a well-accepted mechanism that extracts energy from kink waves. Nonlinear kink waves are know to…
The effect of magnetic field on the damping of slow waves in the solar corona
T. J. Duckenfield, D. Y. Kolotkov, V. M. Nakariakov
Slow magnetoacoustic waves are routinely observed in astrophysical plasma systems such as the solar corona. As a slow wave propagates through a plasma, it modifies the equilibrium…
Seismological constraints on the solar coronal heating function
D. Y. Kolotkov, T. J. Duckenfield, V. M. Nakariakov
The hot solar corona exists because of the balance between radiative and conductive cooling and some counteracting heating mechanism which remains one of the major puzzles in solar…
