Bifrost spectral inversions, Fast non-LTE solar chromospheric diagnostics from 3D simulations
Elias R. Udnæs, Tiago M. D. Pereira, Ignasi J. Soler Poquet +1
Modern solar observatories produce vast amounts of detailed spectral data. To infer atmospheric parameters from these data, in particular for the solar chromosphere, requires immen…
Formation of H in the solar atmosphere
K. Krikova, T. M. D. Pereira, L. H. M. Rouppe van der Voort
Aims. We aim to understand how Hepsilon is formed in the quiet Sun. In particular, we consider the particular physical mechanism that sets its source function and extinction, how i…
Shape-based clustering of synthetic Stokes profiles using k-means and k-Shape
Thore Espedal Moe, Tiago M. D. Pereira, Flavio Calvo +1
The shapes of Stokes profiles contain much information about the atmospheric conditions that produced them. However, a variety of different atmospheric structures can produce very…
Irregular grids for 3D NLTE radiative transfer in stellar atmospheres
Elias R. Udnæs, Tiago M. D. Pereira
Context. Three-dimensional non-local thermodynamical equilibrium (NLTE) radiative transfer calculations are a fundamental tool for a detailed spectral analysis in stellar atmospher…
Effects of spatial resolution on inferences of atmospheric quantities from simulations
Thore E. Moe, Tiago M. D. Pereira, Mats Carlsson
Small scale processes are thought to be important for the dynamics of the solar atmosphere. While numerical resolution fundamentally limits their inclusion in MHD simulations, real…
SunnyNet: A neural network approach to 3D non-LTE radiative transfer
Bruce A. Chappell, Tiago M. D. Pereira
Context. Computing spectra from 3D simulations of stellar atmospheres when allowing for departures from local thermodynamic equilibrium (non-LTE) is computationally very intensive.…
