Asteroseismology is a powerful tool to study stellar structure and dynamics as well as their evolution. The Kepler space telescope provides unprecedented photometric data, enabling us to perform such analysis for thousands of stars. To unfold the full potential of seismology the precise fundamental parameter from spectroscopy is needed and allows an accurate determination of mass and radius of the star. In turn, seismology provides important inferences on the internal structure such as the evolutionary state and rotational gradient from which the spectral interpretation of stars benefits.
In this talk we discus the combination of seismic, photometry and spectroscopic methods to investigate the connection of parameters such as age, rotation, activity, and also specific surface element abundance of solar-like oscillating stars. For binaries with at least one oscillating component, the combination of spectroscopy and seismology provides even further constraints. Both methods allow us to derive several fundamental parameters in redundant ways and compare the results. By combing numerous techniques like spectroscopy, light curve modeling and asteroseismology, we can draw comprehensive pictures of the studied binary systems and constrain the systems properties and history.
