The Chemical Evolution Of High Z Galaxies From The Relative Abundances Of N, Si, S, And Fe In Damped Lyman Alpha Systems
R. B. C. Henry, Jason X. Prochaska
Abundances of N, Si, S, and Fe for 45 damped Lyman alpha systems (DLAs) have been compiled and detailed one-zone chemical evolution models have been constructed for 30 of them. Ass…
ELSA: An Integrated, Semi-Automated Nebular Abundance Package
M. D. Johnson, J. S. Levitt, R. B. C. Henry +1
We present ELSA, a new modular software package, written in C, to analyze and manage spectroscopic data from emission-line objects. In addition to calculating plasma diagnostics an…
Sulfur, Chlorine, and Argon Abundances in Planetary Nebulae. IV: Synthesis and the Sulfur Anomaly
R. B. C. Henry, K. B. Kwitter, Bruce Balick
We have compiled a large sample of O, Ne, S, Cl, and Ar abundances which have been determined for 85 galactic planetary nebulae in a consistent and homogeneous manner using spectra…
