Scientific paper

In order to understand the structural evolution of the sun during the last seven millenia we have studied and analysed the evolution of solar luminosity obtained from a carbon-14 proxy. From the obtained luminosity distribution, we found that the mean luminosity is 0.12%-0.14% lower that the adopted luminosity value used on the standard solar model. The large standard deviation of the luminosity distribution of the Sun reveals a more active evolution of the Sun than previously expected. Furthermore, we have studying the Sun evolution model's response to this luminosity variations under several evolution scenarios.
