Caltech Core-Collapse Project (CCCP) observations of type IIn supernovae: typical properties and implications for their progenitor stars
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/31
Type IIn Supernovae (SNe IIn) are rare events, constituting only a few percent of all core-collapse SNe, and the current sample of well observed SNe IIn is small. Here, we study the four SNe IIn obser...
Hubble Space Telescope Studies of Nearby Type Ia Supernovae: The Mean Maximum Light Ultraviolet Spectrum and its Dispersion
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present the first results of an ongoing campaign using the STIS spectrograph on-board the Hubble Space Telescope (HST) whose primary goal is the study of near ultraviolet (UV) spectra of local Type...
A new multi-dimensional general relativistic neutrino hydrodynamics code for core-collapse supernovae. I. Method and code tests in spherical symmetry
general relativistic core-collapse supernovae neutrino hydrodynamics code
2010/3/19
We present a new general relativistic (GR) code for hydrodynamic supernova simulations with neutrino transport in spherical and azimuthal symmetry (1D/2D). The code is a combination of the CoCoNuT hyd...
It may account for more than 80% of the matter in the universe and provide the "gravitational glue" that keeps galaxies together, but dark matter remains a mystery – despite tantalizing hints obtained...
Rapid Neutron Capture Process in Supernovae and Chemical Element Formation
Supernova—nucleosynthesis—abundance—r-process
2010/9/15
The rapid neutron capture process (r-process) is one of the major nucleosynthesis processes responsible for the synthesis of heavy nuclei beyond iron. Isotopes beyond Fe are most exclusively formed in...
