Galactic archeology aims to study the structure and evolution of our galaxy by measuring ages and chemical compositions of stellar populations in different parts of the Milky Way. Several large observing programs are currently underway to obtain spectra of stellar populations such as the APOGEE survey, the GALAH survey, SAGA, LAMOST and the Gaia-ESO survey. I am a board member of the APOGEE-Kepler Asteroseismic Science Consortium collaboration (APOKASC), a member of the GALAH survey, and a science team member and working group lead within the Maunakea Spectroscopic Explorer (MSE) Project.
The combination of spectroscopy with asteroseismology in red giant stars is a particularly powerful combination for galactic archeology, since it allows the precise determinations of masses (and thus ages) as well as chemical compositions. Another advantage is that the red giants are very luminous, and hence can be observed out to very large distances. A particularly exciting prospect for galactic archeology and asteroseismology is the K2 Mission, which observes different parts of the galaxy in each campaign. The K2 Galactic Archeology Program aims to provide asteroseismic parameters for these different populations. The animation below shows a model of the different populations in our galaxy that will be observed. We expect to continue to expand this reach with data from the NASA TESS mission.
