Nearby massive star explosion 30 million years ago equaled detonation of 100 million suns
massive star explosion 30 million years ago detonation of 100 million suns
2016/5/6
A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, according to astrophysicists at Southern Methodist ...

Blast Wave Parameters for Spherical Explosives Detonation in Free Air
ANFO, Blast Wave, Duration, Explosive, Impulse, Overpressure, PETN, TNT
2013/1/28
Several formulations have been published to define the characteristic parameters of an incident blast wave. In almost all previous work, the charge examined has been TNT explosive and overpressure has...
Confronting 2D delayed-detonation models with light curves and spectra of Type Ia supernovae
supernovae: general
2011/9/26
We compare models for Type Ia supernova (SN Ia) light curves and spectra with an extensive set of observations. The models come from a recent survey of 44 two-dimensional delayed-detonation models com...

Periodic oscillation and fine structure of wedge-induced oblique detonation waves
Oblique detonation wave Wedge Periodic oscillation·Fine structure
2012/2/28
An oblique detonation wave for a Mach 7 inlet flow over a long enough wedge of 30 turning angle is simulated numerically using Euler equation and one-step rection model. The fifth-order WENO scheme is...
Double Detonation of Sub-Chandrasekhar White Dwarfs and Subluminous Type Ia Supernovae
Sub-Chandrasekhar White Dwarfs Subluminous Type Ia Supernovae
2011/1/11
Type Ia supernovae are thought to result from thermonuclear explosions of carbon-oxygen white dwarf stars. This model generally explains the observed properties with certain exceptions, like sub-lumin...
Efficient numerical stability analysis of detonation waves in ZND
Efficient numerical stability analysis detonation waves in ZND
2010/11/9
As described in the classic works of Lee--Stewart and Short--Stewart, the numerical evaluation of linear stability of planar detonation waves is a computationally intensive problem of considerable int...
The criterion of the existence or inexistence of transverse shock wave at wedge supported oblique detonation wave
Oblique detonation wave Transverse shock wave Oblique shock wave Transition Numerical simulations
2012/2/29
A simplified theoretic method and numerical simulations were carried out to investigate the characterization of propagation of transverse shock wave at wedge supported oblique detonation wave. After s...
Numerical study on three-dimensional flow field of continuously rotating detonation in a toroidal chamber
continuously rotating detonation three-dimensional flow field structure numerical study detonation parameters deficit effects of wall geometries
2012/2/24
Gaseous detonation propagating in a toroidal chamber was numerically studied for hydrogen/oxygen/ni-trogen mixtures. The numerical method used is based on the three-dimensional Euler equations with de...
