PHAT XX. AGB stars and other cool giants in M31 star clusters
Leo Girardi, Martha L. Boyer, L. Clifton Johnson +20
The presence of AGB stars in clusters provides key constraints for stellar models, as has been demonstrated with historical data from the Magellanic Clouds. In this work, we look f…
Combined Effects of Rotation and Age Spreads on Extended Main Sequence Turn Offs
Seth Gossage, Charlie Conroy, Aaron Dotter +10
The extended main sequence turn offs (eMSTOs) of several young to intermediate age clusters are examined in the Magellanic Clouds and the Milky Way. We explore the effects of exten…
A Dramatic Decrease in Carbon Star Formation in M31
M. L. Boyer, B. F. Williams, B. Aringer +8
We analyze resolved stellar near-infrared photometry of 21 HST fields in M31 to constrain the impact of metallicity on the formation of carbon stars. Observations of nearby galaxie…
Self-consistent predictions for LIER-like emission lines from post-AGB stars
Nell Byler, Julianne J. Dalcanton, Charlie Conroy +4
Early type galaxies (ETGs) frequently show emission from warm ionized gas. These Low Ionization Emission Regions (LIERs) were originally attributed to a central, low-luminosity act…
Age Determinations of the Hyades, Praesepe, and Pleiades via MESA Models with Rotation
Seth Gossage, Charlie Conroy, Aaron Dotter +4
The Hyades, Praesepe, and Pleiades are well studied stellar clusters that anchor important secondary stellar age indicators. Recent studies have shown that main sequence turn off-b…
Panchromatic Hubble Andromeda Treasury. XIX. The Ancient Star Formation History of the M31 Disk
Benjamin F. Williams, Andrew E. Dolphin, Julianne J. Dalcanton +7
We map the star formation history across M31 by fitting stellar evolution models to color-magnitude diagrams of each 8383 (0.31.4 kpc, deprojected) region o…
