Investigating the inferred spatiotemporal evolution of magnetic fields during an X1-class flare
Dimitri Arramy, Jaime de la Cruz Rodríguez, Adur Pastor Yabar +1
Several observational studies have reported sudden temporal changes in chromospheric magnetic fields inferred during solar flares using the weak-field approximation (WFA) and nonlo…
Chromospheric heating and magnetic topology above the shared penumbra of a delta-spot: Multi-line inversions and multi-height magnetic-field extrapolations
M. Kriginsky, J. Leenaarts, J. de la Cruz Rodríguez +1
We analysed observations of the Fe I 617.3 nm, Ca II 854.2 nm, and Ca II H lines obtained with CRISP and CHROMIS at the SST. Spatially coupled non-LTE inversions constrained the ch…
The IRIS inversion tool: recovering the radiative losses and the thermodynamics in the lower solar atmosphere
Alberto Sainz Dalda, Jaime de la Cruz Rodríguez, Viggo Hansteen +2
We introduce an improved and fast inversion tool that is able to provide the thermodynamics of the solar atmosphere from the photosphere to the top of the chromosphere, as well as…
Characterization of telecentric dual-etalon Fabry-Pérot systems from observational data. Properties of the CRISP2 instrument at the Swedish 1-m Solar Telescope
J. de la Cruz Rodríguez, G. B. Scharmer, P. Sütterlin +5
Imaging Fabry-Pérot Interferometer (FPI) observations are commonly used in solar physics to infer physical parameters in the photosphere and chromosphere through modeling of the ob…
The making of robust and highly performing imaging spectropolarimeters for large solar telescopes
G. B. Scharmer, J. de la Cruz Rodríguez, J. Leenaarts +7
We discuss the requirements, concepts, simulations, implementation, and calibration of two dual Fabry-Perot based imaging spectropolarimeters, CRISP and CHROMIS, at the Swedish 1-m…
Jacobian-Free Newton-Krylov method for multilevel NLTE radiative transfer problems
D. Arramy, J. de la Cruz Rodríguez, J. Leenaarts
The calculation of the emerging radiation from a model atmosphere requires knowledge of the emissivity and absorption coefficients, which are proportional to the atomic level popul…
