Fairly straightforward question. Imagine a gas giant planet, like the size of Jupiter, in orbit around a massive star. The star goes supernova. What happens to the planet? Is the energy of the su...
I did a little looking and it appears stars outside of 10 parsec/33 ly will have very little effect on the Earth. What it did say was that inside that range the gamma rays would affect our ozone l...
I'm building a S-Type binary system where the primary star is a black hole. Yet the system formed as a O + K-Spectral class binary and the 20 solar-mass O giant went nova 2,7 myr after both the sta...
The Sun has nowhere near enough mass to enter the branch of stellar evolution that would lead to a supernova, fortunately for us. However, there are planets that orbit stars that are destined to go...
Storm fronts — especially surprise storm fronts — are a popular Sci-Fi trope. Ion storms and radiation storms and neutronic storms and they invariably look 2D, like ribbons in space. But then I r...
I'm well aware that a Sun-like star is incapable of producing a supernova at the end of its life. However, would removing the core or a fraction of it, trigger an explosion from the star collapsing...
What technology (at minimum), devices or minimum civilization development is needed, so that an individual member of this civilization would be able to detect that some star is going supernova? My...
I want to have aliens approach the Earth looking for a new world to colonize. They come from a similar planet circling a similar star, but either their star has entered its red giant phase (how lon...
As far as I know stars are going supernova as a natural process. Can aliens trigger it artificially? If this is possible then: How can I do this (what minimum technology and civilization develop...
So, you have the big bad race, whose extermination method is basically to force stars to go supercritical via the power of handwavium. You can assume 1 solar mass for each, but you can change it if...
In a class discussion last week, someone pointed out that a typical core collapse supernova releases $\sim10^{46}\text{ J}$ of energy in the form of (anti-)neutrinos while only radiating $\sim10^{4...
Death of stars are fun and make for a great premise, but the actual dying of stars that are conducive to intelligent life aren't so interesting. Stars that can go supernova are too short-lived to h...
Assuming in a galaxy far far away there is a Type 2 civilization (currently on the verge of making the transition to Type 3). Their scientists predicted that the star (red giant) they are orbiting...
The Eternal Emperor wants to throw a party the likes of which the galaxy has never seen. The billionth anniversary of his reign is fast approaching (a mere hundred thousand years away!). He has bro...
In my story where thousands of humans are transported to the planet with dinosaurs that is 400 light years away, there are bound to be lots of warnings on the generation ship. Friendly aliens are t...
You are an intelligent species whose sun is very near expiring. When your sun expires your world will be engulfed by it. You are evacuating your planet as fast as possible but you don't yet have en...
My story revolves around a star going supernova. The 'Earth' in this story is about 100 light-years or more away (a safe distance, but not too far away). I need this supernova to somehow accelerate...
