Red giant masses and ages derived from carbon and nitrogen abundances
Marie Martig, Morgan Fouesneau, Hans-Walter Rix +7
We show that the masses of red giant stars can be well predicted from their photospheric carbon and nitrogen abundances, in conjunction with their spectroscopic stellar labels log…
Dust and molecules in extra-galactic planetary nebulae
D. A. Garcia-Hernandez
Extra-galactic planetary nebulae (PNe) permit the study of dust and molecules in metallicity environments other than the Galaxy. Their known distances lower the number of free para…
Clear evidence for the presence of second-generation asymptotic giant branch stars in metal-poor Galactic globular clusters
D. A. Garcia-Hernandez, Sz. Meszaros, M. Monelli +5
Galactic globular clusters (GCs) are known to host multiple stellar populations: a first generation with a chemical pattern typical of halo field stars and a second generation (SG)…
High resolution imaging of NGC 2346 with GSAOI/GeMS: disentangling the planetary nebula molecular structure to understand its origin and evolution
Arturo Manchado, Letizia Stanghellini, Eva Villaver +3
We present high spatial resolution ( 60--90 milliarcseconds) images of the molecular hydrogen emission in the Planetary Nebula (PN) NGC 2346. The data were acquired during…
Chemical Cartography with APOGEE: Metallicity Distribution Functions and the Chemical Structure of the Milky Way Disk
Michael R. Hayden, Jo Bovy, Jon A. Holtzman +32
Using a sample of 69,919 red giants from the SDSS-III/APOGEE Data Release 12, we measure the distribution of stars in the [/Fe] vs. [Fe/H] plane and the metallicity distribution…
Exploring Anticorrelations and Light Element Variations in Northern Globular Clusters Observed by the APOGEE Survey
Szabolcs Meszaros, Sarah L. Martell, Matthew Shetrone +20
We investigate the light-element behavior of red giant stars in Northern globular clusters (GCs) observed by the SDSS-III Apache Point Observatory Galactic Evolution Experiment (AP…
