Signatures of Explosion Models for SN ~Ia & Cosmology
P. Hoeflich
We give an overview of the current understanding of Type Ia supernovae relevant for their use as cosmological distance indicators. We present the physical basis to understand their…
Asphericity Effects in Supernovae
P. Hoeflich, C. Gerardy, R. Quimby
We present a brief summary of asphericity effects in thermonuclear and core collapse supernovae (SN), and how to distinguish the underlying physics by their observable signatures.…
A New Population of Old Stars
I. I. Ivans, C. Sneden, C. R. James +5
We report the results of a coherent study of three chemically anomalous metal-poor ([Fe/H] ~ -2) stars. These objects exhibit unusually low abundances of Mg, Si, Ca (alpha-elements…
Aspherical Supernovae Explosions
P. Hoeflich, A. Khokhlov, L. Wang +2
Core collapse supernovae(SN) are the final stages of evolution in massive stars during which the central region collapses. Recent explosion scenarios assumed that the ejection is d…
Stellar Sources of the Interstellar Medium
F. -K. Thielemann, D. Argast, F. Brachwitz +14
With the exception of the Big Bang, responsible for 1,2H, 3,4He, and 7Li, stars act as sources for the composition of the interstellar medium. Cosmic rays are related to the latter…
Models for SNeIa and Evolutionary Effects with Redshift
Peter Hoeflich
Based on detailed models for the explosions, light curves and NLTE-spectra, evolutionary effects of Type Ia Supernovae (SNe Ia) with redshift have been studied to evaluate their si…
