Astrophysical explosions result from the release of magnetic, gravitational,
or thermonuclear energy on dynamical timescales, typically the sound-crossing
time for the system. These explosions include solar and stellar flares,
eruptive phenomena in accretion disks, thermonuclear combustion on the surfaces
of white dwarfs and neutron stars, violent magnetic reconnection in neutron
stars, thermonuclear and gravitational collapse supernovae and cosmic gamma-ray
bursts, each representing a different type and amount of energy release. This
paper summarizes the properties of these explosions and describes new research
on thermonuclear explosions and explosions in extended circumstellar media.
Parallels are drawn between studies of terrestrial and astrophysical
explosions, especially the physics of the transition from deflagration to
detonation.
Keywords: neutron stars, black holes, supernovae, gamma-ray bursts,
deflagration, detonation.
