The objective of the Helio- and Asteroseismology Network is to co-ordinate activities among those European institutions and organisations that support Europe’s major research groups in helio- and asteroseismology. The transfer of knowledge, data, and data analysis techniques through HELAS will achieve a structuring of this field of research that is essentially needed to prepare the European research community for important opportunities in the immediate future.

Combining the core competences of the individual research groups through the network activities of HELAS, the activity will:

• ensure European competence and competitiveness in helio- and asteroseismology by spreading expertise,
• increase in volume and quality the European scientific output in this research area,
• enhance the synergy between helio- and asteroseismology,
• improve the public understanding and interest in solar and stellar physics.
