Web9 gen 2024 · A supernova is a transient astronomical event that occurs during the last stellar evolutionary stages of a massive star’s life, whose dramatic and catastrophic destruction is marked by one final titanic explosion. The researchers had ruled out the possibility that the observed object is a star pair or comets, halos and terrestrial events. WebA supernova remnant, also known as SNR, is a nebula left behind after the explosion of a star in a supernova. This is a spectacular explosion in which a star ejects most of its …

WebHB9 (G160.9+2.6) is a mixed-morphology Galactic supernova remnant (SNR) at a distance of $\sim$0.6 kpc. Previous analyses revealed recombining plasma emission in X-rays and an expanding shell structure in HI and CO emission, which were correlating with the spatial extent of HB9. In GeV energies, HB9 was found to show extended gamma-ray emission … WebThe Vela supernova remnant is a supernova remnant in the southern constellation Vela.

WebBack to Results. A large radio galaxy behind the supernova remnant HB9 HB9 is a 2-deg-diameter radio shell with X-ray emission from a broad diffuse band in the interior. Within this band, a weak unresolved X-ray source coincides with the radio source 4C 46.09. To identify this source CCD I and V band pictures and a spectrum were obtained. industrial flameless heaters
