Sub-Commission E2: The Sun as a Star

Cristina Mandrini, Chair, Sub-Commission E2


Peng-Fei Chen, Vice-Chair, Sub-Commission E2

Cristina Mandrini, C. (Argentina), 2022 – 2026*

Yuhong Fan, Vice-Chair, Sub-Commission E2


Peng Fei Chen (China), 2022 – 2026*
Yuhong Fan (USA), 2022 – 2026*

Terms of Reference

Sub-commission E2 deals with the study of the Sun as a star including, in particular, the theoretical and observational study of solar structure and radiation. The latter topics cover the solar interior structure and dynamics, the mechanism of solar magnetic cycles, the structure and dynamics of the lower solar atmosphere and of its magnetic field because of their relevance and implications to the understanding of the solar-stellar connection, and in the same line the sources of solar irradiance and long-term variability.

Silvano Fineschi (Italy), 2021 – 2024
Susanna Parenti (France), 2021 – 2024

Terms of Reference

(1) Observational and theoretical study of the phenomena of the quiet and active sun in the photosphere, chromosphere, and corona that relate to energy release in form of coronal heating, solar wind acceleration, energetic particle generation, flares and coronal mass ejections.

(2) Observational and theoretical study of the subsequent phenomena in the inner heliosphere and of the processes governing its structure, such as fast and slow solar wind streams, interplanetary coronal mass ejections and shock waves, solar energetic particles, corotating interaction regions including their space weather effects.


Sub-Commission B6/E4: Exoplanets Detection, Characterization and Modelling


Francesca Altieri (Italy), 2022 – 2026*


Michael Ireland (Australia), 2022 – 2026*

Terms of Reference

Sub-commission B6/E4 deals with Exoplanets detection, characterization and modelling.

The recent discoveries of nearly a thousand of extrasolar planetary systems have opened up a number of new questions about their properties, physical conditions along with a rethinking of the concepts of habitability and life. In this context, it is not obvious whether a planetary system like our own solar system is common or unusual in the Galaxy. Planets may form and orbit around stars of almost every kind. We have found many planets which we call exotic, i.e. very close to their parent star, in highly eccentric orbits, or around binary systems, in a word very different from planets in our solar system.

Recent observations have shown how diverse can be the physical conditions of planets, both in structure, with fluffy or very dense planets, and in the composition and atmospheric stratification.  The key word is diversity.

Understanding the origin of such diversity is the goal of many of the new studies and current projects. Such activities may cover both scientific and technological aspects and could include:

  • Analysis of the current and proposed projects for future observations
  • Analysis of diversity of extrasolar planet
  • The Solar System in the context of extrasolar planetary systems
  • Definition, even non-conventional, of habitability and life
  • Definition and detectability of organic pre-biotic material and biomarkers
  • Laboratory activity supporting modelling and atmospheric properties studies
