What can stellar metallicity tell about galactic outflow? I 

will be talking about the stellar-phase mass - metallicity relation of 

quiescent galaxies and its evolution with redshift. I will show how the 

relation can be used to constrain mass-loading factor as a function 

of mass. Other possible applications include: 1) to determine 

whether quiescent galaxies evolve passively; and 2) to compare 

stellar metallicity with gas-phase metallicity in star-forming galaxies 

without directly measuring stellar metallicities in star-forming galaxies.
