AsteroFLAG: first results from hare-and-hounds Exercise #1

W. J. Chaplin, T. Appourchaux, T. Arentoft, J. Ballot, J. Christensen-Dalsgaard, O. L. Creevey, Y. Elsworth, S. T. Fletcher, R. Garcia, G. Houdek, S. J. Jimenez-Reyes, H. Kjeldsen, R. New, C. Régulo, D. Salabert, T. Sekii, S. G. Sousa, T. Toutain, the rest of the asteroFLAG group

We report on initial results from the first phase of Exercise #1 of the asteroFLAG hare and hounds. The asteroFLAG group is helping to prepare for the asteroseismology component of NASA’s Kepler mission, and the first phase of Exercise #1 is concerned with testing extraction of estimates of the large and small frequency spacings of the low-degree p modes from Kepler-like artificial data. These  seismic frequency spacings will provide key input for complementing the exoplanet search data.

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.
