SN 2013fs was recorded three hours after the supernova event on 6 October 2013, by the Intermediate Palomar Transient Factory. This is among the earliest supernovae caught after detonation, and it is the earliest for which spectra have been obtained, beginning six hours after the actual explosion.
Supernova nucleosynthesis is the nucleosynthesis of chemical elements in supernova explosions.. In sufficiently massive stars, the nucleosynthesis by fusion of lighter elements into heavier ones occurs during sequential hydrostatic burning processes called helium burning, carbon burning, oxygen burning, and silicon burning, in which the byproducts of one nuclear fuel become, after ...
If the circumstellar medium extends further from the supernova, the mid-infrared brightening can cause an infrared echo, causing the brightening to last more than 1000 days. These kind of supernovae belong to the rare 2010jl-like supernovae, named after the archetypal SN 2010jl.
The attack happened in the final hours of Supernova, a marathon trance music event held in honour of the Sukkot festival. The dancing began at 11pm and continued all night, at the festival ...
SN 1988Z was a prototypical [2] type IIn supernova event in the equatorial constellation of Leo. The apparent host is an irregular galaxy with the designation MCG +03-28-22. [1] It has a redshift of z equal to 0.0225. [1] This was a very luminous supernova that faded unusually slowly and has remained detectable three decades after the event.
Just after dawn on Oct. 7, Hamas militants attacked the Supernova music festival in southern Israel, murdering at least 260 festivalgoers and taking an unknown number of hostages. NBC News has ...
Supernova nucleosynthesis within exploding stars is largely responsible for the elements between oxygen and rubidium: from the ejection of elements produced during stellar nucleosynthesis; through explosive nucleosynthesis during the supernova explosion; and from the r-process (absorption of multiple neutrons) during the explosion.
Boom.In the colossal Pinwheel galaxy, 25 million light-years away, a star has just exploded and is even visible through small telescopes. The supernova-hunting astronomer Koichi Itagaki discovered ...
