The long term dynamics of the solar radiative zone associated to new results from SoHO and young solar analogs

TL;DR

This paper reviews recent observational data from SoHO and young solar analogs to improve understanding of the solar radiative zone's long-term dynamics beyond the Standard Solar Model, highlighting missing processes and future implications.

Contribution

It introduces new insights from SoHO and young star observations to enhance models of the solar radiative zone's evolution beyond traditional assumptions.

Findings

Recent data challenge the Standard Solar Model assumptions.

Identification of missing physical processes in current models.

Progress towards more realistic stellar evolution models.

Abstract

The Standard Solar Model (SSM) is no more sufficient to interpret all the observations of the radiative zone obtained with the SoHO satellite. We recall our present knowledge of this internal region and compare the recent results to models beyond the SSM assumptions. Then we discuss the missing processes and quantify some of them in using young analog observations to build a more realistic view of our star. This progress will be useful for solar-like stars observed by COROT and KEPLER.
