Lundmark gives a list of 60 suspected novae, then the generic term for a stellar explosion, in fact covering what is now understood as two distinct phenomena, novae and supernovae. The nova of 1054, already mentioned by the Biots in 1843, [7] is part of the list. It stipulates the location of this guest star in a note at the bottom of the page ...
Astronomers studying the site of a supernova seen 843 years ago have captured an image of the strange filaments left behind by the stellar explosion.
They confirmed its difference from known explosions such as novae and thermal pulses, and announced luminous red novae as a new class of stellar explosion. [1] V1309 Scorpii is a luminous red nova that followed the merger of a contact binary in 2008. [2] In January 2015, a luminous red nova was observed in the Andromeda Galaxy. [3]
Some of the flares only lasted tens of seconds, which to astronomers suggests that the underlying cause is a stellar remnant formed by the initial explosion — either a dense neutron star or a ...
Later in its life, a low-mass star will slowly eject its atmosphere via stellar wind, forming a planetary nebula, while a higher–mass star will eject mass via a sudden catastrophic event called a supernova. The term supernova nucleosynthesis is used to describe the creation of elements during the explosion of a massive star or white dwarf.
