Differential population studies using asteroseismology: solar-like oscillating giants in CoRoT fields LRc01 and LRa01

TL;DR

This paper discusses how solar-like oscillating giants observed by CoRoT can serve as tracers of stellar populations in the Milky Way, providing insights into their distances, masses, and ages through pulsation spectra analysis.

Contribution

It offers a comparative analysis of giant star populations in two CoRoT fields, enhancing understanding of stellar population differences.

Findings

Distinct stellar population characteristics identified in LRc01 and LRa01 fields

Pulsation spectra enable accurate estimates of stellar radii and masses

Data supports using giants as proxies for Galactic evolution studies

Abstract

Solar-like oscillating giants observed by the space-borne satellites CoRoT and Kepler can be used as key tracers of stellar populations in the Milky Way. When combined with additional photometric/spectroscopic constraints, the pulsation spectra of solar-like oscillating giant stars not only reveal their radii, and hence distances, but also provide well-constrained estimates of their masses, which can be used as proxies for the ages of these evolved stars. In this contribution we provide supplementary material to the comparison we presented in Miglio et al. (2013) between populations of giants observed by CoRoT in the fields designated LRc01 and LRa01.
