Conference: Stellar Coronae in the Chandra and XMM-Newton Era

25 - 29 June, 2001

ESTEC, Noordwijk, The Netherlands

Results from earlier generations of X-ray and EUV observatories (Einstein, EXOSAT, ROSAT, ASCA, SAX, EUVE) over the past two decades have opened up the field of stellar coronae, while solar observations have greatly advanced our view of the only stellar corona that we can study with spatial resolution. However, the observational advances and discoveries have left many open questions regarding the nature of stellar outer atmospheres. Fundamental issues such as coronal heating, the spatial distribution of stellar coronal plasma, and the nature and presence of elemental fractionation and abundance anomalies, remain outstanding problems. Much also remains to be explored concerning the existence and role of hot stellar coronae in the broader context of the HR diagram, in star formation and in other areas of astronomy.

Thanks to their high sensitivity and spectral resolution, the data obtained by the Chandra and XMM-Newton missions are providing a new look at the coronae of stars. At the same time, the spectacular successes of the SoHO and TRACE missions are providing the most detailed spatial and spectral views ever obtained of the solar corona. The aim of this conference is to provide a timely forum for a detailed discussion of the impact of the new generation of data on coronal astronomy at large, bringing together observers and theoreticians, as well as experts in other disciplines of relevance, such as stellar structure and star formation.
