Cool stars are fundamental astrophysical laboratories. On the H-R diagram they span a vast range of gravities, luminosities, and, thus, internal structures. As a result, they probe a plethora of distances and are preferential targets of past and current Galactic surveys (e.g., 2MASS, SDSS, RAVE, Gaia-ESO, APOGEE, GALAH, Kepler, LSST, SAGA). Be it a dwarf or a giant, their cool surface temperatures are the realm of interesting atomic and molecular physics that shape their emergent spectra. This temperature regime is dominated by convection, which is the main driver underlying the fundamental oscillations detected by asteroseismology.
Cool stars are thus at the cross-roads of a number of areas in astronomy. To best exploit cool stars, we must accurately and precisely measure their observational properties with Galactic surveys. This is only possible if we have realistic models to both guide and interpret observations. For example, the orbits and chemical compositions of cool stars provide an unprecedented fossil record of different epochs of star formation. However, only with advanced stellar modeling can we determine reliable stellar ages and distances, allowing us to constrain Galactic evolution.
The purpose of this Splinter Session is to bring together experts from both observational and theoretical stellar astronomy to highlight successes, discuss problems and failures, and explore new ideas to use Cool Stars for Galactic studies. This session features two panel discussions, one focused on surveys and the other on theory. Prior to the meeting, we request that registered participants contribute topics and questions for the discussion in the comment section below. Each panelist will briefly discuss the audience-proposed topics and questions, after which the session will shift to a discussion between the panelists and audience.

We welcome topics and questions for these panel discussions. Audience participation, both before and during the meeting, is critical to the success of the Galactic Archaeology with Cool Stars session.
