Supernova leaves total annihilation

There is a lot of recent reporting of Supernova 2016iet, this article in Sky & Telescope sums it up nicely.
https://www.skyandtelescope.com/astr...oyed-its-star/

Not a BOSS team discovery, but certainly great to read that the science is revealing more and more about Supernova. But it all begins with someone finding them.

It's also encouraging that the many, many hours we have put into to finding Supernova in the last 10 years has and may further add some value to the science of Supernova. A number of science papers have already been published about some of our discoveries and we understand there are several more in the pipeline.

While the Professional All Sky surveys are pretty much hoovering up the skies, there is still room for keen amateur astronomers to find there own (as we did last month with NGC6753 / SN2019mh). Perhaps to even join professional groups like ASASSN out of Ohio State University, as ad- hoc contributors in confirming their discoveries. They are very generous in their recognition of contributing amateur astronomers - who they recognise as "unpaid professional astronomers"

Point is, just when we think we know it all in say Supernova Astro Science we don't, there is more to be done and if you want you can still have a valuable input.

Thanks for posting that Peter, great read.
very interesting.
Goes to show there is a hell of a lot more to
learn about Supernovae.
Read some of the paper,will read the rest later.
Cheers

Fascinating read, I did a bit of research on these kinds of supernova back in 2014 when doing my Masters on how metallicity affected the evolution of globular clusters in the early universe. I wasn’t aware that any supernova had been flagged for this since the first stellar epoch! Waiting for JWST to officially discover supernova from the first epoch; out of the detection of Hubble.

VERY low metallicity in the early universe tended towards larger, hotter and faster burning stars. This means a higher chance of pair-instability supernova but also the formation of more larger blackholes to feed the early galaxies. As metallicity increases the average stellar mass decreases as does temperate at the same stellar size due to “impurities” (metals).

What an interest time on which we live
