RESEARCHERS AT ABERYSTWYTH
Postdoctoral researcher at Aberystwyth university.
Due to the high complexity of the solar atmosphere, advanced, high-resolution spectropolarimetric observations are required to investigate its
thermodynamic properties including the characteristics of the magnetic field. High-resolution, full Stokes chromospheric spectropolarimetry
from ground-based telescopes offers the opportunity to obtain such data sets. My research focus on design, execution, analysis and
interpretation of ground-based spectropolarimetric observations.
The main aim of my current projects are:
Figure 1. Solar spicule in Hβ line wing at ∆λ = −0.699 Å observed at the western limb of the Sun with Swedish Solar telescope (SST).
The size of this structure is about 9,000 km.
Figure 2. A composite of SST Hβ ± 0.455 Å images of the X8.2 flare coronal loops on 10 September 2017.
- Develop semi-empirical radiative hydrodynamic models of the chromospheric structures through advanced spectropolarimetric inversion techniques.
- Perform diagnostics of the key plasma parameters, such as temperature, density, plasma pressure, magnetic field and velocity.
- Study the spatial and temporal variation of the physical parameters in the chromospheric structures and their magnetohydrodynamic stability.
