A fast method for Stokes profile synthesis -- Radiative transfer modeling for ZDI and Stokes profile inversion
T. A. Carroll, M. Kopf, K. G. Strassmeier
The major challenges for a fully polarized radiative transfer driven approach to Zeeman-Doppler imaging are still the enormous computational requirements. In every cycle of the ite…
PCA detection and denoising of Zeeman signatures in stellar polarised spectra
M. J. Martinez Gonzalez, A. Asensio Ramos, T. A. Carroll +3
Our main objective is to develop a denoising strategy to increase the signal to noise ratio of individual spectral lines of stellar spectropolarimetric observations. We use a multi…
Zeeman-Tomography of the Solar Photosphere -- 3-Dimensional Surface Structures Retrieved from Hinode Observations
T. A. Carroll, M. Kopf
AIMS :The thermodynamic and magnetic field structure of the solar photosphere is analyzed by means of a novel 3-dimensional spectropolarimetric inversion and reconstruction techniq…
Zeeman-Doppler Imaging of Late-Type Stars -- The Surface Magnetic Field of II Peg
T. A. Carroll, M. Kopf, I. Ilyin +1
Late-type stars in general possess complicated magnetic surface fields which makes their detection and in particular their modeling and reconstruction challenging. In this work we…
The Characteristic Length Scale of the Magnetic Fluctuation in a Sunspot Penumbra: A Stochastic Polarized Radiative Transfer Approach
T. A. Carroll, J. Staude
The characteristic size of penumbral structures are still below the current resolution limit of modern solar telescopes. Though we have seen a significant progress in theoretical w…
Stokes Profile Inversion in Meso-Structured Magnetic Atmospheres
T. A. Carroll
Based on the Meso-Structured Magnetic Atmosphere (MESMA) approximation, recently introduced by Carroll & Kopf (2007), we present first results of an inversion of spectropolarimetri…
