Panchromatic Hubble Andromeda Treasury XII. Mapping Stellar Metallicity Distributions in M31
Dylan Gregersen, Anil C. Seth, Benjamin F. Williams +14
We present a study of spatial variations in the metallicity of old red giant branch stars in the Andromeda galaxy. Photometric metallicity estimates are derived by interpolating is…
A Spectroscopic and Photometric Exploration of the C/M Ratio in the Disk of M31
Katherine M. Hamren, Constance M. Rockosi, Puragra Guhathakurta +12
We explore the ratio (C/M) of carbon-rich to oxygen-rich thermally pulsing asymptotic giant branch(TP-AGB) stars in the disk of M31 using a combination of moderate-resolution optic…
A clear age-velocity dispersion correlation in Andromeda's stellar disk
Claire E. Dorman, Puragra Guhathakurta, Anil C. Seth +9
The stellar kinematics of galactic disks are key to constraining disk formation and evolution processes. In this paper, for the first time, we measure the stellar age-velocity disp…
