Case A and B evolution towards electron capture supernova

ELECTRON CAPTURE RATES OF MID-fp SHELL NUCLEI FOR SUPERNOVA AND STELLAR EVOLUTION S.Chakravarti, K.Kar, A.Ray and S.Sarkar

A detailed model is constructed for the calculation of electron capture rates of some fp shell nuclei for situations prevailing in pre-supernova and collapse phases of the evolution of the core of massive stars leading to supernova explosion. The model uses explicitly the Gamow-Teller strength function obtained through (n,p) reaction studies wherever available. The rates include contribution fr...

Evolution of Marginal Zone Lymphoma Towards Myeloproliferative Disorder: A Case Report

Neutrino Capture Induced Supernova Explosions

Motivated by the success of kinetic theory in the description of observables in intermediate and high energy heavy ion collisions, we use kinetic theory to model the dynamics of core collapse supernovae. The specific way that we employ kinetic theory to solve the relevant transport equations allows us to explicitly model the propagation of neutrinos and a full ensemble of nuclei and treat neutr...

Towards Resolving the Evolution of Multi-Supernova Superbubbles

Interstellar superbubbles generated by multiple supernova explosions are common in star-forming galaxies. They are the most obvious manifestation of mechanical feedback, and are largely responsible for transferring both thermal and kinetic energy to the interstellar medium from the massive star population. However, the details of this energy transfer remain surprisingly murky when individual ob...
