The LF of TP-AGB stars in the LMC and SMC
Gustavo Bruzual, Stephane Charlot, Rosa Gonzalez Lopezlira +3
We show that Montecarlo simulations of the TP-AGB stellar population in the LMC and SMC galaxies using the CB* models produce LF and color distributions that are in closer agreemen…
On the metallicity dependence of crystalline silicates in oxygen-rich asymptotic giant branch stars and red supergiants
O. C. Jones, F. Kemper, B. A. Sargent +10
We investigate the occurrence of crystalline silicates in oxygen-rich evolved stars across a range of metallicities and mass-loss rates. It has been suggested that the crystalline…
Fundamental parameters and infrared excesses of Hipparcos stars
Iain McDonald, Albert A. Zijlstra, Martha L. Boyer
We derive the fundamental parameters (temperature and luminosity) of 107 619 Hipparcos stars and place these stars on a true Hertzsprung-Russell diagram. This is achieved by compar…
The Contribution of TP-AGB and RHeB Stars to the Near-IR Luminosity of Local Galaxies: Implications for Stellar Mass Measurements of High Redshift Galaxies
J. Melbourne, Benjamin F. Williams, Julianne J. Dalcanton +9
Using high spatial resolution HST WFC3 and ACS imaging of resolved stellar populations, we constrain the contribution of thermally-pulsing asymptotic giant branch (TP-AGB) stars an…
The Dust Budget of the SMC: Are AGB Stars the Primary Dust Source at Low Metallicity?
Martha L. Boyer, S. Srinivasan, D. Riebel +7
We estimate the total dust input from the cool evolved stars in the Small Magellanic Cloud (SMC), using the 8 micron excess emission as a proxy for the dust-production rate. We fin…
