Calculation of the Solar UV/EUV Spectrum in Spherical Symmetry

TL;DR

This paper discusses the development of spectral synthesis calculations for the solar UV/EUV spectrum using spherical symmetry, validating the models against recent observational data from the EVE instrument.

Contribution

It introduces a spherical symmetry approach in spectral synthesis for solar UV/EUV, demonstrating good agreement with observed spectra during solar minimum.

Findings

Synthetic spectrum matches EVE observations well

Atmosphere structures used are suitable for irradiance calculations

Validates spherical symmetry modeling for solar spectrum

Abstract

We present work in progress concerning spectral synthesis calculations of the solar UV/EUV in spherical symmetry carried out with the Solar Radiation Physical Modeling (SRPM) project. We compare the synthetic irradiance spectrum for the quiet Sun with the recent solar minimum spectrum taken with the EVE rocket instrument. The good agreement of the synthetic spectrum with the observation shows that the employed atmosphere structures are suitable for irradiance calculations.
