ASPCAP: The Apogee Stellar Parameter and Chemical Abundances Pipeline
Ana E. García Pérez, Carlos Allende Prieto, Jon A. Holtzman +27
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) has built the largest moderately high-resolution (R=22, 500) spectroscopic map of the stars across the Milky Way…
AGB stars in the SMC: evolution and dust properties based on Spitzer observations
F. Dell'Agli, D. A. García-Hernández, P. Ventura +3
We study the population of asymptotic giant branch (AGB) stars in the Small Magellanic Cloud (SMC) by means of full evolutionary models of stars of mass 1Msun < M < 8Msun, evolved…
A test for asymptotic giant branch evolution theories: Planetary Nebulae in the Large Magellanic Cloud
P. Ventura, L. Stanghellini, F. Dell'Agli +2
We used a new generation of asymptotic giant branch (AGB) stellar models that include dust formation in the stellar winds to find the links between evolutionary models and the obse…
Rapid Rotation of Low-Mass Red Giants Using APOKASC: A Measure of Interaction Rates on the Post-main-sequence
Jamie Tayar, Tugdual Ceillier, D. A. García-Hernández +16
We investigate the occurrence rate of rapidly rotating (10 km s), low-mass giant stars in the APOGEE-Kepler (APOKASC) fields with asteroseismic mass and surface…
The Large Magellanic Cloud as a laboratory for Hot Bottom Burning in massive Asymptotic Giant Branch stars
P. Ventura, A. I. Karakas, F. Dell'Agli +4
We use Spitzer observations of the rich population of Asymptotic Giant Branch stars in the Large Magellanic Cloud (LMC) to test models describing the internal structure and nucleos…
Constraint on the time variation of the fine-structure constant with the SDSS-III/BOSS DR12 quasar sample
Franco D. Albareti, Johan Comparat, Carlos M. Gutiérrez +9
From the Sloan Digital Sky Survey (SDSS) Data Release 12, which covers the full Baryonic Oscillation Spectroscopic Survey (BOSS) footprint, we investigate the possible variation of…
