Nucleosynthetic signatures of the first stars
Anna Frebel, Wako Aoki, Norbert Christlieb +16
The chemically most primitive stars provide constraints on the nature of the first stellar objects that formed in the Universe; elements other than hydrogen, helium and traces of l…
Supernova light curve models for the bump in the Optical Counterpart of X-Ray Flash 030723
N. Tominaga, J. Deng, P. A. Mazzali +5
XRF 030723 is the first X-ray flash (XRF) to show in its optical light curve (LC) a bump that has been interpreted as the signature of a supernova (SN). After subtracting the after…
High-resolution optical studies of nearby Type Ia supernovae
Peter Lundqvist, Seppo Mattila, Jesper Sollerman +5
Since April 2000, a program using the ESO/VLT/UVES to search for early circumstellar signatures from nearby supernovae has been conducted. Until now, two Type Ia supernovae have be…
Hypernovae and their Nucleosynthesis
Ken'ichi Nomoto, Keiichi Maeda, Hideyuki Umeda +3
We review the characteristics of nucleosynthesis in 'Hypernovae', i.e., core-collapse supernovae with very large explosion energies ($ \gsim 10^{52} $ ergs). The hypernova yields s…
Pop III Hypernova Nucleosynthesis and Abundances in Very Metal-Poor Halo Stars
Hideyuki Umeda, Ken'ichi Nomoto
We calculate evolution and nucleosynthesis in massive Pop III stars with M = 13 ~ 270Msun, and compare the results with abundances of very metal-poor halo stars. The observed abund…
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…
