Core-collapse supernovae are a puzzle that has taxed
theorists and computational science for half a century.
Such explosions are the source of many of the heavy elements
in the Universe and the birthplace of neutron stars and
stellar-mass black holes. However, determining the mechanism
of explosion remains the key goal of theory. Recently,
using sophisticated numerical tools and...

A core-collapse supernova event begins with a nearly spherical hydrodynamic implosion
of the core of a massive star and ends with a hydrodynamic explosion as an aspherical
shock wave expands through the stellar envelope. The breaking of spherical symmetry
is both critical for driving the explosion as well as determining the characteristics
of the supernova. The origin of asymmetry may...

The talk will review 2D and 3D modeling of core-collapse
supernova explosions by the Garching group. It will address
the question of the explosion mechanism and the role of
relativistic effects, of the neutron star equation of state,
and of dimensionality (2D vs. 3D) in this context. Observational
consequences of the explosion mechanism will also be discussed.

Supernovae are observationally characterized by their lightcurves, spectra,
late time radioactivities in remnants and their integrated contribution to
chemical evolution, witnessed in observations of old stars. We will highlight
open questions with respect to nucleosynthesis contributions from core collapse
supernovae. While many aspects of intermediate mass (alpha) elements...

The properties of supernovae associated with GRBs & XRFs, and some other
related supernovae are summarized. Discussion includes the possible
connection to the unusual supernovae, such as extremely luminous and
extremely faint supernovae. The abundance patterns predicted in their
nucleosynthesis are compared with those of metal-poor halo stars, DLAs, and
other related objects.

Observations of SNe light at early times can open a window to a wealth of information
on the progenitor system and the explosion itself. I will present the theoretical
expectation of that emission, starting at the shock breakout, through the planar
phase and into at the spherical phase, until recombination and/or radioactive decay
start playing a role. I will discuss separately Newtonian...
