I have a question regarding Supernova SN1987A. I was wondering if anyone could tell me if the gas ring that surrounds it was the result of the explosion itself, or if it was there prior to it?
This site here: http://www-astronomy.mps.ohio-state.edu/~pogge/Ast162/Unit3/supernova.html gives a good explanation of Type II supernovae (like 1987A) and even explains the expanding gass shells and shockwave as you are discussing.Oblivion said:Ok that's what I figured, but this brings up another question: the gas ring is supposed to become more visible as the shockwave approaches. However, I was wondering how the gas ring got outside the shockwave in the first place, and why is there a difference in velocity between the two?
Supernova SN1987 is a type II supernova explosion that occurred in the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. It is significant because it was the closest supernova to Earth in over 400 years and one of the brightest events observed in modern astronomy.
Supernova SN1987 occurred on February 23, 1987.
The distance of Supernova SN1987 from Earth is approximately 168,000 light years.
Supernova SN1987 was caused by the collapse of a massive star, known as a red supergiant, at the end of its life. This collapse led to a massive explosion, releasing a tremendous amount of energy and creating the supernova.
The observation of Supernova SN1987 provided important insights into the processes of stellar evolution and the mechanisms of supernova explosions. It also helped confirm many existing theories and provided new data for further research in the field of astrophysics.
