Discovery of New Type of Supernova Illuminates Medieval Mystery


Housing and Development Newsletter
The team found the supernova SN 2018zd had many unusual characteristics, some of which were seen for the first time in a supernova.
It helped that the supernova was relatively nearby only 31 million light-years away in the galaxy NGC 2146. This allowed the team to examine archival images taken by the Hubble Space Telescope prior to the explosion and to detect the likely progenitor star before it exploded.
The observations were consistent with another recently identified SAGB star in the Milky Way, but inconsistent with models of red supergiants, the progenitors of normal iron core-collapse supernovae.
The authors looked through all published data on supernovae, and found that while some had a few of the indicators predicted for electron-capture supernovae, only SN 2018zd had all six: an apparent SAGB progenitor, strong pre-supernova mass loss, an unusual stellar chemical composition, a weak explosion, little radioactivity, and ....

An Extreme Supernova Lit The Skies 1,000 Years Ago. We May Finally Know Its Type


30 JUNE 2021
Way back in 1054 CE, a supernova stellar explosion lit up the skies with enough brightness that it could be seen from from Earth during the daytime, for 23 days straight.
Its remnants still exist today as the Crab Nebula, and new research gives us our best idea yet of exactly what happened to cause such a phenomenon.
 
Based on an analysis of a more recent supernova labeled SN 2018zd, astronomers think both SN 2018zd and the 1054 CE supernova are electron-capture supernovae – a rare third type of supernova alongside type I (thermonuclear) and type II (core collapse).
Experts have hypothesized about this third type of exploding star for decades at this point, though actual physical evidence of electron-capture supernovae has been difficult to come by. The unusual characteristics of SN 2018zd – a mere 31 million light-years away – may be the first one we ve actually properly identified. ....
