Contribution

It provides a comprehensive review of photometric methods, calibrations, and the integration of classical and asteroseismic data for stellar and Galactic research.

Findings

Photometric systems encode key stellar parameters.

Combining classical and asteroseismic data improves accuracy.

Calibrations for late-type stars are summarized.

Abstract

Asteroseismology has the capability of delivering stellar properties which would otherwise be inaccessible, such as radii, masses and thus ages of stars. When coupling this information with classical determinations of stellar parameters, such as metallicities, effective temperatures and angular diameters, powerful new diagnostics for both stellar and Galactic studies can be obtained. I review how different photometric systems and filters carry important information on classical stellar parameters, the accuracy at which those parameters can be derived, and summarize some of the calibrations available in the literature for late-type stars. Recent efforts in combining classical and asteroseismic parameters are discussed, and the unique- ness of their intertwine is highlighted.
