Singapore)

• represents the "galaxy" that is home to our solar system.

• is the Sun or Earth or planets.• symbolizes a fern for new life, similar to the

significance attached to it by the Maoris of New Zealand, and also expresses our linkage to the Oceania. The G also resembles a whirling cloud in the atmospheres.

• represents the oceanic waves - and lee waves as well for the familiar scientists.

Solar Flares and Coronal Mass Ejections

Brief DescriptionSolar flares and coronal mass ejections (CMEs) are fundamental key factors controlling space weather. Recent development of space solar observations such as by Yohkoh, SOHO, TRACE, and RHESSI has revealed that the solar atmosphere is full of reconnection events, and there are increasing evidence of reconnection in solar flares and coronal mass ejections, which leads to a unified view of these phenomena. It is now necessary to review and summarize recent observations and theories of solar flares and CMEs in a unified and critical way. In this session, considering these. both solar flares and CMEs are discussed in detail, especially on following topics, (1) preflare/preCME conditions, (2) particle acceleration associated with them, (3) coronal and interplanetary shock waves, and (4) theoretical models.

 

Introduction to the session SP7: Solar Flares and Coronal Mass Ejections – Unified View and Key Issues

K. Shibata

Kyoto University

1st AOGS meeting, @Singapore 2004 July 7

Purpose of this session

• Solar flares and coronal mass ejections (CMEs) are fundamental key factors controlling solar-terrestrial environment and space weather.

• Recent development of space solar observations such as by Yohkoh, SOHO, TRACE, and RHESSI has revealed that the solar atmosphere is full of reconnection events, and there are increasing evidence of reconnection in flares and CMEs, which leads to a unified view of these phenomena.

• It is now necessary to review and summarize recent observations and theories of solar flares and CMEs in a unified and critical way.

Key Questions

• Where are reconnection inflows/outflows and assoiated MHD slow/fast shocks in flares/CMEs ?

• What is the relation between mass ejections and reconnection in flares/CMEs ?

• Can we unify flares and CMEs ?– Are CMEs ideal MHD process (Low) ?

Or are CMEs a part of resistive MHD processes involving flares (Shibata) ?

• What is the preflare/preCME conditions ?• What is the natue of flare associated waves/shocks

(EIT waves and Moreton waves) ?• What is the particle acceleration mechanism in flares/CM

Es ?
