Improvements in stellar ages in the era of Gaia
Abstract
We present estimates of the distances; ages and masses for nearly 5;5 million stars from public spectroscopic surveys. To derive these estimates we use Gaia DR2 parallax values; spectroscopic parameters as well as infra-red photometry. These estimates were obtained with the third version of the Unified tool to estimate Distances; Ages; and Masses (UniDAM); which introduced the use of optical photometry and (where available) asteroseismic data.
