Ground‐based follow‐up in relation to Kepler asteroseismic investigation

The Kepler space mission, successfully launched in March 2009, is providing continuous and high‐precision photometry of thousands of stars simultaneously. The uninterrupted time‐series of stars of all known pulsation types are a precious source for asteroseismic studies. The Kepler data do not provide information on the physical parameters, such as log g , metallicity, and v sin i , which are crucial for successful asteroseismic modelling. Additional ground‐based time‐series data are needed to characterize mode parameters in several types of pulsating stars. Therefore, ground‐based multi‐colour photometry and mid/high‐resolution spectroscopy are needed to complement the space data. We present ground‐based activities within KASC on selected asteroseismic Kepler targets of several pulsation types (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
