Limitations of the Ca II 8542 Å line for the determination of magnetic field oscillations
T. Felipe, H. Socas Navarro, C. R. Sangeetha +1
Chromospheric umbral oscillations produce periodic brightenings in the core of some spectral lines, known as umbral flashes. They are also accompanied by fluctuations in velocity,…
The Lightweaver Framework for NLTE Radiative Transfer in Python
Christopher M J Osborne, Ivan Milić
Tools for computing detailed optically thick spectral line profiles out of local thermodynamic equilibrium have always been focused on speed, due to the large computational effort…
Are the Magnetic Fields Radial in the Solar Polar Region?
Xudong Sun, Yang Liu, Ivan Milić +1
We investigate the orientation of the photospheric magnetic fields in the solar polar region using observations from the Helioseismic and Magnetic Imager (HMI). Inside small patche…
Chromospheric resonances above sunspots and potential seismological applications
T. Felipe, C. Kuckein, S. J. González Manrique +2
Oscillations in sunspot umbrae exhibit remarkable differences between the photosphere and chromosphere. We evaluate two competing scenarios proposed for explaining those observatio…
Mimicking spectropolarimetric inversions using convolutional neural networks
Ivan Milic, Ricardo Gafeira
Interpreting spectropolarimetric observations of the solar atmosphere takes much longer than the acquiring the data. The most important reason for this is that the model fitting, o…
Using the infrared iron lines to probe solar subsurface convection
Ivan Milic, Smitha Narayanamurthy, Andreas Lagg
Studying the properties of the solar convection using high-resolution spectropolarimetry began in the early 90's with the focus on observations in the visible wavelength regions. I…
