"Workshop on Galactic archaeology - Asteroseismology"
Date: March 22, 2016
Venue: "Cosmos-Kaikan" conference room, Mitaka campus of NAOJ
Age information of stars is crucial to our understanding of the chemical evolution of the Galaxy. Precise photometric observations from space telescopes enable us to determine mass of stars with asteroseismic scaling relations. The mass information is used to estimate ages of stars with stellar evolution models. Following the success of CoRoT and Kepler missions, the TESS will be launched in 2017 and observe stars with high photometric precision across the whole sky, though its main target is identification of exoplanets. In this workshop, we would like to discuss how the ongoing projects of asteroseismology will improve our understanding of the chemical evolution of the Galaxy.
