Stationary Mach Configurations with Pulsed Energy Release on the Normal Shock

Fluids, 2021
We obtained a theoretical analysis of stationary Mach configurations of shock waves with a pulsed energy release at the main (normal) shock and a corresponding change in gas thermodynamic properties.

Three Hypervelocity White Dwarfs in Gaia DR2: Evidence for Dynamically Driven Double-degenerate Double-detonation Type Ia Supernovae [PDF]

Astrophysical Journal, 2018
Double detonations in double white dwarf (WD) binaries undergoing unstable mass transfer have emerged in recent years as one of the most promising Type Ia supernova (SN Ia) progenitor scenarios.

Introduction to "To the Question of Energy Use of Detonation Combustion" by Ya. B. Zel'dovich [PDF]

, 2006
Ya. B. Zel’dovich (1914–1987) made numerous contributions [1] to the theory of detonation, beginning with his very well known and widely translated article [2] on detonation structure that first introduced the standard Zel’dovich-von Neumann-Döring (ZND)

A unified mechanism for unconfined deflagration-to-detonation transition in terrestrial chemical systems and type Ia supernovae [PDF]

Science, 2019
Achieving unconfined supersonic explosions In some forms of supernovae and chemical explosions, a flame moving at subsonic speeds (deflagration) spontaneously evolves into one driven by a supersonic shock (detonation), vastly increasing the power output.

Helium in Double-Detonation Models of Type Ia Supernovae [PDF]

, 2016
The double-detonation explosion model has been considered a candidate for explaining astrophysical transients with a wide range of luminosities. In this model, a carbon-oxygen white dwarf star explodes following detonation of a surface layer of helium ...

In situ measurement of the particle size distribution of the fragmentation product of laser-shock-melted aluminum using in-line picosecond holography

AIP Advances, 2016
The dynamic fragmentation of shock-melted metal is a topic of increasing interest in shock physics. However, high-quality experimental studies of the phenomenon are limited, and data that are essential for developing predictive models of the phenomenon ...

Study of detonation interactions inside a 2-D ejector using detonation transmission tubing [PDF]

, 2010
Study of detonation interactions inside a two-dimensional ejector using detonation transmission tubing was reported. The main objective of the ejector assembly in the study is to make the flow-field as close to 2-D as possible.

Double-detonation supernovae of sub-Chandrasekhar mass white dwarfs

, 2007
In the "double-detonation sub-Chandrasekhar" model for type Ia supernovae, a carbon-oxygen (C + O) white dwarf accumulates sufficient amounts of helium such that a detonation ignites in that layer before the Chandrasekhar mass is reached. This detonation
