THE ACTION OF NEUTRINO PONDEROMOTIVE FORCE ON SUPERNOVA DYNAMICS [PDF]

Modern Physics Letters A, 1999
Collective interactions of a beam of neutrinos/antineutrinos traversing a dense magnetized plasma of electrons/positrons, protons and neutrons are studied with particular reference to the case of a supernova. We find that the ponderomotive force exerted by neutrinos gives, contrary to expectations, a negligible contribution to the revival of the shock

Dynamical Collective Calculation of Supernova Neutrino Signals [PDF]

Physical Review Letters, 2009
We present the first calculations with three flavors of collective and shock wave effects for neutrino propagation in core-collapse supernovae using hydroynamical density profiles and the S matrix formalism. We explore the interplay between the neutrino-neutrino interaction and the effects of multiple resonances upon the time signal of positrons in ...

A Novel Sparse Cellular Labeling System with Tunable Gradients and Long-Term Stability. [PDF]

Adv Sci (Weinh)
The Tri‐M (Multi‐recombinase, Multi‐recognition site, and Multi‐nested) sparse cellular labeling system, built upon competitive recombination, integrates transgenic mice with viral injection to achieve tunable and long‐term stable sparse labeling of specific cell types with region selectivity, from sparse populations to individual cells, facilitating ...

Dynamics of Type-II Supernovae [PDF]

International Astronomical Union Colloquium, 1996
Hydrodynamical simulations of type-II supernovae in one and two dimensions are performed for the revival phase of the delayed shock by neutrino energy deposition. Starting with a post-collapse model of the 1.31 Mʘ iron core of a 15 Mʘ star immediately after the stagnation of the prompt shock about 10 ms after core bounce, the models are followed for ...

Photo‐Induced Stepwise Liquid Crystal Phase Transition Enabled by Hydrazone Photoswitch [PDF]

Advanced science
A judiciously designed bistable hydrazone photoswitch enables a photo‐induced stepwise “order‐disorder” phase transition in liquid crystals. The linear‐to‐bent isomerization disrupts molecular packing, allowing precise tuning of phase transition temperatures.

Dynamics of a supernova envelope in a cloudy interstellar medium [PDF]

Astronomy Reports, 2015
The evolution of a supernova remnant in a cloudy medium as a function of the volume filling factor of the clouds is studied in a three-dimensional axially symmetrical model. The model includes the mixing of heavy elements (metals) ejected by the supernova and their contribution to radiative losses.

The Dynamics, Destruction, and Survival of Supernova-formed Dust Grains [PDF]

The Astrophysical Journal, 2020
Abstract Observations have demonstrated that supernovae efficiently produce dust. This is consistent with the hypothesis that supernovae and asymptotic giant branch stars are the primary producers of dust in the universe. However, there has been a longstanding question of how much of the dust detected in the interiors of young supernova ...

Dynamics of massive shells ejected in a supernova explosion [PDF]

Physics Letters A, 1996
An expanding shell is accelerated outward by radiation from the remnant star and slowed by ram pressure and accretion as it plows into the interstellar medium. We set up the general relativistic equations of motion for such a shell. In the non-relativistic limit, the reduce to the standard Ostriker-Gunn equations.

Statistical classification techniques for photometric supernova typing [PDF]

, 2010
Future photometric supernova surveys will produce vastly more candidates than can be followed up spectroscopically, highlighting the need for effective classification methods based on light curves alone.
