Flash: An adaptive mesh hydrodynamics code for modeling astrophysical thermonuclear flashes
The first version of a new-generation simulation code, FLASH, solves the fully compressible, reactive hydrodynamic equations and allows for the use of adaptive mesh refinement and contains state-of-the-art modules for the equations of state and thermonuclear reaction networks.
Spontaneous Initiation of Detonations in White Dwarf Environments: Determination of Critical Sizes
Some explosion models for Type Ia supernovae (SNe Ia), such as the gravitationally confined detonation (GCD) or the double detonation sub-Chandrasekhar (DDSC) models, rely on the spontaneous
On the evolution of those nuclei of planetary nebulae that experiencea final helium shell flash.
We suggest that some of the central stars of planetary nebulae experience a final thermal pulse having achieved a white dwarf configuration and begun their descent along a cooling white dwarf
The nature of the recurrent novae
The basic properties of individual recurrent nova systems are reviewed, and the mechanisms of their outbursts are studied. Some general properties associated with accretion events and thermonuclear
The C-flame Quenching by Convective Boundary Mixing in Super-AGB Stars and the Formation of Hybrid C/O/Ne White Dwarfs and SN Progenitors
After off-center C ignition in the cores of super asymptotic giant branch (SAGB) stars, the C flame propagates all the way down to the center, trailing behind it the C-shell convective zone, and thus
The supernova trigger for formation of the solar system
Abstract It is suggested that the explosion of a Type II supernova triggered the collapse of a nearby interstellar cloud and led to the formation of the solar system. Estimates of the abundances
The R-process and nucleochronology
Abstract The r-process of nucleosynthesis is the process which is responsible for the synthesis of approximately half of the nuclear species in nature that are more massive than iron. This process of
Evolutionary sequences for Nova V1974 Cygni using new nuclear reaction rates and opacities
Accepted 1997 November 12. Received 1997 September 26; in original form 1997 January 24 ABSTRA C T The outburst of Nova V1974 Cyg 1992 is arguably the best observed of this century, with realistic
Helium shell detonations on low-mass white dwarfs as a possible explanation for SN 2005E
Recently, several Type Ib supernovae (SNe; with the prototypical SN 2005E) have been shown to have atypical properties. These SNe are faint (absolute peak magnitude of {approx} - 15) and fast SNe
