But astronomers are hedging their bets on V445 Puppis.
Messier 46 also known as M 46 or NGC 2437 is an open cluster in the constellation of Puppis.

Open Cluster M47 also known as Messier Object 47 or NGC 2422 is an open cluster in the constellation Puppis.
“Whether V445 Puppis will eventually explode as a supernova, or if the current nova outburst has pre-empted that pathway by ejecting too much matter back into space is still unclear,” said Patrick Woudt, from the University of Cape Town and lead author of the paper reporting the results.
V445 Puppis are among th so-called pre-Asymptotic Giant Branch pre-AGB stars, approximately between 5M? and 11M?
Gomez's Hamburger is one example (similar mechanism to V445 Puppis); M82 is another (rather different mechanism); and 3C272.1 a third (very different mechanism, although one may not consider to have a classic hourglass shape!)
There was a faint but unmistakable tinge of blue to his skin tone that tagged him as either a native of Rho Puppis 'three habitable worlds or a Tucanite addict.
