Description
Different age-dating techniques can produce very different results. The main culprit for this state of affairs is the lack of a universal age scale and the absence of a systematic and robust cross-calibration of the various methods. This situation can change due to the availability of several massive database (Gaia, Cosmic-DANCe, Kepler, Gaia-ESO) and the development of state-of-the-art theoretical models. The CHRONOS project will start with the simplest, least model dependant techniques and will apply them to well known open clusters and associations. It will build up sequentially starting from first principles, observations and simple and well understood physical phenomena, such as Lithium Depletion Boundary and kinematics. These will then be used to bridge the gaps and anchor other precise but relative or model-dependent age scales such as the gyrochronology and asteroseismology to make the ultimate self-consistent universal age scale covering the entire astrophysical time domain.
