Seismology of rapidly rotating stars

Abstract
Interpreting the frequency spectrum of rapidly rotating stars is a long standing unsolved problem of stellar seismology, that prevents a detailed seismic diagnostic of typical intermediate-mass and massive stars. The quality of the spatial data together with the advances in modelling bring fresh perspectives towards a successful comparison between theory and observation.
I shall present recent progresses in modelling the effects of rapid rotation on stellar oscillation modes and their possible application to the mode identification problem.

Institute of Astrophysics and Space Sciences

Institute of Astrophysics and Space Sciences (IA) is a new but long anticipated research infrastructure with a national dimension. It embodies a bold but feasible vision for the development of Astronomy, Astrophysics and Space Sciences in Portugal, taking full advantage and fully realizing the potential created by the national membership of the European Space Agency (ESA) and the European Southern Observatory (ESO). IA resulted from the merging the two most prominent research units in the field in Portugal: the Centre for Astrophysics of the University of Porto (CAUP) and the Center for Astronomy and Astrophysics of the University of Lisbon (CAAUL). It currently hosts more than two-thirds of all active researchers working in Space Sciences in Portugal, and is responsible for an even greater fraction of the national productivity in international ISI journals in the area of Space Sciences. This is the scientific area with the highest relative impact factor (1.65 times above the international average) and the field with the highest average number of citations per article for Portugal.
