A High-Resolution Three-Dimensional Model of the Solar Photosphere Derived from Hinode Observations

TL;DR

This paper presents a high-resolution 3D model of the solar photosphere derived from Hinode spectro-polarimetric data, offering a detailed and accurate representation without reliance on simulations.

Contribution

The model is uniquely obtained through inversion of observational data rather than numerical simulations, providing a new approach for solar atmospheric modeling.

Findings

Model fits observed Hinode data accurately

Model reproduces previous solar atlas observations

No micro- or macro-turbulence needed for spectral line fitting

Abstract

A new three-dimensional model of the solar photosphere is presented in this paper and made publicly available to the community. This model has the peculiarity that it has been obtained by inverting spectro-polarimetric observations, rather than from numerical radiation hydrodynamical simulations. The data used here are from the spectro-polarimeter onboard the Hinode satellite, which routinely delivers Stokes I, Q, U and V profiles in the 6302 A spectral region with excellent quality, stability and spatial resolution (approximately 0.3"). With such spatial resolution, the major granular components are well resolved, which implies that the derived model needs no micro- or macro-turbulence to properly fit the widths of the observed spectral lines. Not only this model fits the observed data used for its construction, but it can also fit previous solar atlas observations satisfactorily.
