Supernova explosions are sorted into two categories: The thermonuclear explosions triggered by white dwarfs in close binary systems (type Ia) and those triggered by the gravitational collapse of the core of massive stars (type Ib/c and II). Because of the paucity of known supernova remnants younger than 1000 years, astronomers developed several models describing the evolution of supernova remnants to

3DMAP-VR: a project to develop 3D astrophysical models for Virtual Reality

Ricerca

The development of numerical models is a powerful method to explore properties and evolution of astrophysical objects, mainly for remote objects or when the necessary spatial details are higher than the resolution of modern telescopes. These models can be both hydrodynamical or magneto-hydrodynamical, depending on the importance of the effects related to the magnetic fields. In the last years, the

Modelli magnetoidrodinamici di interazione tra resti di supernovae e nubi. Pubblicato su MNRAS “Post-adiabatic supernova remnants in an interstellar magnetic field: oblique shocks and non-uniform environment” di O. Petruk (Institute for Applied Problems in Mechanics and Mathematics – Ucraina)

di Mario Giuseppe Guarcello    ( segui mguarce)     I resti di supernova, ossia uno dei due prodotti di un’esplosione di supernova assieme all’oggetto compatto formato dal nucleo della stella esplosa, sono ritenuti i principali responsabili della produzione di raggi cosmici, che vengono accelerati fino ad energie di 3×1015 eV. L’accelerazione di raggi cosmici caratterizza tutta l’evoluzione dei resti di supernova,
