On Heavy Element Enrichment in Classical Novae
A. Alexakis, A. C. Calder, A. Heger +10
Many classical nova ejecta are enriched in CNO and Ne. Rosner et al. recently suggested that the enrichment might originate in the resonant interaction between large-scale shear fl…
The Response of Model and Astrophysical Thermonuclear Flames to Curvature and Stretch
L. J. Dursi, M. Zingale, A. C. Calder +11
Critically understanding the `standard candle'-like behavior of Type Ia supernovae requires understanding their explosion mechanism. One family of models for Type Ia Supernovae beg…
The Ionizing Efficiency of the First Stars
Aparna Venkatesan, James W. Truran
We investigate whether a single population of first stars could have influenced both the metal enrichment and reionization of the high-redshift intergalactic medium (IGM), by calcu…
The Extremely Metal-Poor, Neutron-Capture-Rich Star CS 22892-052: A Comprehensive Abundance Analysis
C. Sneden, J. J. Cowan, J. E. Lawler +9
High-resolution spectra obtained with three ground-based facilities and the Hubble Space Telescope (HST) have been combined to produce a new abundance analysis of CS 22892-052, an…
