Webb29 juni 2024 · A thermonuclear supernova is the explosion of a white dwarf star after it gains matter in a binary star system. An iron core-collapse supernova occurs when a massive star—one more than about ten times the sun’s mass—runs out of nuclear fuel, and its iron core collapses, creating a black hole or neutron star.

Supernovae of type Ia (SNe Ia) are very important for cosmography. To exclude systematic effects in linking the observed light of distant SNe Ia to the parameters of cosmological models, one has to understand the nature of supernova outbursts and to build accurate algorithms for predicting their emission.

Webb5 apr. 2024 · Supernovae (SNe) are the dominant source of chemical enrichment of galaxies, and they are an important source of energy to heat the interstellar medium and accelerate cosmic rays.

WebbThermonuclear supernova explosions are an astrophysical model for the astronomical class of Type Ia supernovae (SNe Ia henceforth). These objects are of interest in many fields of astrophysics and astronomy. Being one of the main sources of iron group elements, SNe Ia contribute to the chemical evolution of galaxies (e.g., [ 1] ).
