Experiments were carried out to determine the effectiveness of a transient plasma, i.e, corona discharge, to initiate a detonation in a short tube. A high-voltage pulse generator used a pseudo-spark switch to discharge a capacitor through a transformer connected to electrodes in the combustion initiator section. The resulting voltage pulse (90 kV for 50 ns) produced a plasma discharge consistin...

In thermonuclear supernovae, intermediate mass elements are mostly produced by distributed burning provided that a deflagration to detonation transition does not set in. Apart from the two-dimensional study by Röpke & Hillebrandt (2005), very little attention has been payed so far to the correct treatment of this burning regime in numerical simulations. In this article, the physics of distribut...

Neutralization of landmines is dangerous and complicated work. For Humanitarian Demining, the most common neutralization method is demolition using small explosive charges. Although common practice, demolition has several disadvantages. Deminers need non-explosive mine neutralization technologies that are safer, more reliable and less expensive. To meet this need, several innovative non-explosi...

We present optical UBVRI photometry and low-to-medium resolution spectroscopic observations of type Iax SN 2020sck spanning -5.5 d to +67 from maximum light in the B-band. From photometric analysis we find $\Delta m_{\rm{B}}$(15) = 2.03$\pm$0.05 mag $M_{\rm{B}}$=-17.81$\pm$0.22 mag. Radiation diffusion model fit quasi-bolometric curve indicates 0.13$\pm$0.02 $M_{\odot}$ $^{56}$Ni 0.34 $M_{\rm \...

The effects of hydraulic resistance on the burning of confined/obstacle-laden gaseous and gas-permeable solid explosives are discussed on the basis of recent research. Hydraulic resistance is found to induce a new powerful mechanism for the reaction spread (diffusion of pressure) allowing for both fast subsonic as well as supersonic propagation. Hydraulic resistance appears to be of relevance a...

We present theoretical UBVIand bolometric light curves of SNe Ia for several explosion models, computed with our multi-group radiation hydro code. We employ our new corrected treatment for line opacity in the expanding medium. The results are compared with observed light curves. Our goal is to find the most viable thermonuclear SN model that gives good fits not only to a typical SN Ia light cur...
