A pipeline for Solar like oscillation with Kepler
Pierre-Olivier Quirion, Jørgen Christensen-Dalsgaard

Abstract

Many pipelines interested in transforming Kepler's light curves into information about large, small separation and the maximum power frequency have been developed. Parallel to these "data analysis pipelines" (DA pipeline), a series of "modeling pipelines" (M pipeline) have been crafted to make uses of the DA pipeline outputs to pin down stellar parameters.

We have developed SEEK, a M pipeline which is especially potent at expressing realistic error on stellar parameters of Solar like oscillators. SEEK is based and a
fixed stellar grid and makes use of Bayesian statistics to to handle error
analysis. Its quasi instantaneous output speed makes it a perfect tool to process large database. It can also be use to constrain an area of the stellar parameter space prior to the extended computation of a mode by mode asteroseismology analysis. SEEK also comes has a ready to use IDL GUI (Widget) which can be made available on demand.

I present here the main characteristic of SEEK and finally validate the approach by
comparing its output with a list of solar like oscillator having known radius from
interferometric measurements and/or known mass from binarity measurements.
