Asteroseismology of red giants & galactic archaeology [PDF]

, 2017
Red-giant stars are low- to intermediate-mass ($M \lesssim 10$~M$_{\odot}$) stars that have exhausted hydrogen in the core. These extended, cool and hence red stars are key targets for stellar evolution studies as well as galactic studies for several ...

Galactic archaeology: IMF and depletion in the "thin disk"

, 2003
We determine the initial mass function (IMF) of the ``thin disk'' by means of a direct comparison between synthetic stellar samples (for different matching choices of IMF, star formation rate SFR and depletion) and a complete (volume-limited) sample of ...

Massive first star binaries as new tools for Galactic archaeology [PDF]

EPJ Web of Conferences, 2022
Binary systems are important probes of the origin of stars with peculiar chemical features through the interactions between two stars. We have studied the evolution of a metal-free massive binary after the collision of the supernova ejecta with a low ...

The Far Side of the Galactic Bar/Bulge Revealed through Semi-regular Variables

The Astronomical Journal, 2023
The Galactic bulge is critical to our understanding of the Milky Way. However, due to the lack of reliable stellar distances, the structure and kinematics of the bulge/bar beyond the Galactic center have remained largely unexplored.

The Chemical Enrichment of the Milky Way Disk Evaluated Using Conditional Abundances

The Astrophysical Journal, 2023
Chemical abundances of Milky Way disk stars are empirical tracers of its enrichment history. However, they capture joint-information that is valuable to disentangle.

PLATO as it is: A legacy mission for Galactic archaeology [PDF]

Astronomische Nachrichten, 2017
Deciphering the assembly history of the Milky Way is a formidable task, which becomes possible only if one can produce high‐resolution chrono‐chemo‐kinematical maps of the Galaxy. Data from large‐scale astrometric and spectroscopic surveys will soon provide us with a well‐defined view of the current chemo‐kinematical structure of the Milky Way, but it ...

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 ...
