Galactic archaeology with metal-poor stars

, 2017
The chemical fingerprints of old, metal-poor stars can be used to unravel the events of the newborn Universe and help us understand the properties of the first stars and star clusters. The study of nearby stars to infer properties in the distant past is often referred to as Galactic archaeology.

Dynamics for galactic archaeology [PDF]

New Astronomy Reviews, 2013
Our Galaxy is a complex machine in which several processes operate simultaneously: metal-poor gas is accreted, is chemically enriched by dying stars, and then drifts inwards, surrendering its angular momentum to stars; new stars are formed on nearly circular orbits in the equatorial plane and then diffuse through orbit space to eccentric and inclined ...

Galactic archaeology with high temporal resolution [PDF]

, 2023
The study of the formation and evolution of the Milky Way has entered a golden era. Galactic archaeology, enabled by high-precision astrometry and spectroscopy, has equipped us with rich maps of our Galaxy's kinematic and chemical structures.
