Analysing Solar‐like Oscillations with an Automatic Pipeline

The Kepler mission will provide a huge amount of asteroseismic data during the next few years, among which hundreds of solar‐like stars will be targeted. The amount of stars and their observation length represent a step forward in the comprehension of the stellar evolution that has already been initiated by CoRoT and MOST missions. Up to now, the slow cadence of observed targets allowed an individual and personalized analysis of each star. During the survey phase of Kepler, this will be impossible. This is the reason why, within the AsteroFLAG team, we have been developing automatic pipelines for the Kepler solar‐like oscillation stars. Our code starts by finding the frequency‐range where p‐mode power is present and, after fitting the background, it looks for the mode amplitudes as well as the central frequency of the p‐mode hump. A good estimation of the large separation can thus be inferred in this region. If the signal to noise is high enough, the code obtains the characteristics of the p modes by doin...
