The task of accurately determining the fundamental parameters of a star from medium or low resolution spectra is time consuming and requires substantial experience. Since the first large‐scale space missions such as CoRoT or Kepler came along, the need for a fast and statistically sound method emerged to cope with the large amount of ground based support data. We present here a fully automated approach for the determination of stellar parameters from low‐resolution stellar spectra using a Bayesian approach and discuss the reliability and limits of the method (© 2012 WILEY‐VCH Verlag GmbH & Co.
