Socrates/Erasmus Intensive Programme

Computing Atomic Data for Astrophysics using New Technologies

29 March - 8 April 2005, Lund


This EU-funded Intensive Program concerns the calculation of reliable atomic data for astrophysical applications. The emphasis is on developing an understanding of the atomic physics involved, together with the main theoretical and computational methods used. Students follow a series of lectures on atomic structure, collisions and astrophysical modelling. In practical classes, they undertake non-trivial calculations of atomic structure and collisional data using state-of-the-art computer packages. There is also an opportunity to see how this data is used in an astrophysical model.

All mobility costs for students will be covered by the Socrates/Erasmus programme. Students should have a reasonably good command of English, in particular aural comprehension, as all the courses are given in this language. French and Swedish teachers will however be present during the tutorials.

The IP in 2005 will be held at the University of Lund.
