Supernova impostor, stellar explosions that appear similar to supernova, but do not destroy their progenitor stars Failed supernova; Luminous red nova, an explosion thought to be caused by stellar collision; Solar flares are a minor type of stellar explosion [1] Tidal disruption event, the pulling apart of a star by tidal forces
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.
Those powerful jets plough through stellar material produce strong shock waves, with the vigorous winds of newly-formed 56 Ni blowing off the accretion disk, detonating the hypernova explosion. The ejected radioactive decay of 56 Ni renders the visible outburst substantially more luminous than a standard supernova. [ 17 ]
A star is dead? Keep your eyes on the skies, stargazers: NASA has predicted that the much-anticipated “once-in-a-life-time” star explosion — or nova — will be visible to the naked eye ...
Months after astronomers witnessed the explosion of a distant star, they spotted something they have never seen before: energetic signs of life releasing from the stellar corpse about 1 billion ...
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. A supernova first seen in 1181 is releasing ...
A stellar collision is the coming together of two stars [1] caused by stellar dynamics within a star cluster, ... causing a supernova explosion. [4]
The red star M31 RV in the Andromeda Galaxy flared brightly during 1988 and may have been a luminous red nova. In 1994, V4332 Sagittarii, a star in the Milky Way galaxy, flared similarly, and in 2002, V838 Monocerotis followed suit and was studied quite closely. The first confirmed luminous red nova was the object M85 OT2006-1, in the galaxy ...
