Hydra Observations of Aluminum Abundances in the Red Giants of the Globular Clusters M80 and NGC 6752
Robert M. Cavallo, Nicholas B. Suntzeff, Catherine A. Pilachowski
Aluminum and other metal abundances were determined in 21 red giants in the globular clusters NGC 6752 and M80 as part of a larger study to determine whether the aluminum distribut…
Djehuty, a Code for Modeling Stars in Three Dimensions
G. Bazan, D. S. P. Dearborn, D. D. Dossa +10
Current practice in stellar evolution is to employ one-dimensional calculations that quantitatively apply only to a minority of the observed stars (single non-rotating stars, or we…
Preliminary Abundance Analysis of Galactic Bulge Main Sequence, Subgiant, and Giant Branch Stars Observed During Microlensing with Keck/HIRES
R. M. Cavallo, K. H. Cook, D. Minniti +1
We present an abundance analysis of six main sequence turnoff, subgiant, and giant branch stars toward the Galactic bulge that were observed with Keck/HIRES during microlensing eve…
Aluminum Abundances, Deep Mixing and the Blue-Tail Second-Parameter Effect in the Globular Clusters M 3 and M 13
Robert M. Cavallo, Neil M. Nagar
We explore the relatiohsip between deep mixing on the red-giant branch and the second parameter that gives rise to the extended blue tail seen on the horizontal branch of the globu…
Aluminum Abundances on the Red Giant Branch: Testing Helium Mixing as a Second Parameter
R. M. Cavallo
We present new data and discuss the relationship between the Al abundances on the red giant branches (RGBs) and the horizontal-branch (HB) morphologies of the second-parameter pair…
Proton-Capture Nucleosynthesis in Globular Cluster Red Giant Stars
Robert M. Cavallo, Allen V. Sweigart, Roger A. Bell
We follow the static abundance profiles of the C, N, O, Ne, Na, Mg, and Al isotopes around the hydrogen-burning shell (H shell) of globular cluster red-giant-branch (RGB) stellar m…
The Production of Sodium and Aluminum in Globular Cluster Red Giant Stars
Robert M. Cavallo, Allen V. Sweigart, Roger A. Bell
We study the production of Na and Al around the hydrogen shell of two red-giant sequences of different metallicity in order to explain the abundance variations seen in globular clu…
