Three outer jets in Cas A unveil the complex phenomena occurring in the interior of an exploding star. The paper: “Extreme anisotropies in deep layers of an exploding star: overabundance of Cr in the northeastern jet of Cassiopeia A” of V. Sapienza (INAF-OAPA/UNIPA) appeared on ApJL

In the supernova remnant Cassiopeia A, three jets rich in material synthesized in the innermost layers of the progenitor star reveal the secrets of the processes that occur in a supernova immediately after core collapse.   Understanding the phenomena that follow the collapse of a massive star core is one of the most important goals of modern astrophysics. These processes

Jets launched during supernova explosions. The study: “X-ray emitting structures in the Vela SNR: ejecta anisotropies and progenitor stellar wind residuals” of V. Sapienza (UNIPA/OAPA) recently appeared on A&A

Supernova remnants are clouds in rapid expansion formed by supernova explosions. Typically, these remnants are very inhomogeneous. These inhomogeneity is the result of the interaction between the expanding remnant and the surrounding material, and, in particular when they are generated by core-collapse supernova explosions (which are the supernova triggered by the gravitational collapse of the cores of massive stars), also to anisotropies formed

IC 443: un caso unico di SNR con jet sovra-ionizzato

Senza categoria, Slider

di Mario Giuseppe Guarcello    ( segui mguarce)     Lo studio dei resti di supernova, nubi formate dalle esplosioni di supernova, sono oggetti di grande interesse scientifico. Queste nebulose, infatti, non sono semplicemente il residuo di uno dei fenomeni più violenti che  avvengono nell’Universo (un’esplosione di supernova dal collasso di una stella massiva, ossia le “core-collapse supernovae”, produce un’energia pari
