Lithium Inventory of 2 Red Clump Stars in Open Clusters: A Test of the Helium Flash Mechanism
Joleen K. Carlberg, Katia Cunha, Verne V. Smith
The temperature distribution of field Li-rich red giants suggests the presence of a population of Li-rich red clump (RC) stars. One proposed explanation for this population is that…
Chemical Abundances in a Sample of Red Giants in the Open Cluster NGC 2420 from APOGEE
Diogo Souto, Katia Cunha, Verne Smith +20
NGC 2420 is a 2 Gyr-old well-populated open cluster that lies about 2 kpc beyond the solar circle, in the general direction of the Galactic anti-center. Most previous abundan…
Chemical abundance gradients from open clusters in the Milky Way disk: results from the APOGEE survey
Katia Cunha, Peter M. Frinchaboy, Diogo Souto +23
Metallicity gradients provide strong constraints for understanding the chemical evolution of the Galaxy. We report on radial abundance gradients of Fe, Ni, Ca, Si, and Mg obtained…
