Seismic studies of stars

After the dramatic success of helioseismology in probing the internal structure of the Sun, an extension to asteroseismic investigations of other stars is essential to secure a broader observational base for the understanding of stellar structure and evolution, and for probing the properties of matter under stellar conditions.

Following many questionable results over the past two decades such studies are finally becoming possible thanks to major developments of observational techniques. The development of very stable spectrographs, largely motivated by the search for extrasolar planets, has enabled ground-based observations at the required level of sensitivity.

Futhermore, within a few years, space-based observations will allow extended studies of huge number of stars. In parallel with these observational developments, substantial development is also taking place in the procedures for stellar modelling, particular with regards to the treatment of the effects of convection and rotation.

The goal of the Danish AsteroSeismology Centre is to place the Danish astrophysical community in the forefront of the exploitation of these new asteroseismic opportunities, by organizing and carrying out observations, develop and apply data analysis and modelling tools, and preparing for participation in the upcoming space projects.
