J140747B the "Super Saturn" (Could magnetar turn planet or star to a black hole?)
J140747B is the exoplanet, which orbits the sun-looking star in Centauri constellation. This exoplanet or "brown dwarf" is called as "Saturn with steroids". The nickname for that object is formed because of its very large ring system, what size is about 0,6 AU, and this is the thing, that makes this object so interesting.
The question, in this case, is, how that exoplanet could be so powerful magnet or gravity field that this kind of phenomenon is forming. And there is given a very good explanation for those very large rings. That explanation is that the nucleus of that planet is hitting extremely high power beta- or commonly saying electron ray, which would increase its rotation speed, and made that huge ring system possible.
So, if some magnetar or neutron star would send the electron flare to that planet, it could get that magnet field, which is so powerful that it can create that kind of phenomenon. This would happen in the cases, where that kind of electron bursts hits the rocky planets, and that can cause crushing the lithosphere.
And here we must realize that the gas giants like Saturn are more flexible and they can survive that kind of catastrophe. So what will happen if that kind of electric flare would give steroids to our solar system planets like Saturn or Jupiter? The problem is that if that kind of magnetic flare would hit the Saturn or Jupiter it can turn them to the stars or brown dwarf. And that kind of thing can affect the entire solar system. As an example, the atmosphere of Earth would get warmed, and that causes problems.
But the thing has brought one thing in the mind of researchers, and that is the possibility that some magnetar would send it's ray to some star, and if that electric shock would be long and high power enough, that thing can cause that the star would blow as the supernova or even turn to black hole.
And the thing is that this kind of eruption can form the planet to a black hole as well as the stars. How long that kind of black hole could live is depending on how much energy it would get. If the small black hole would be alone in the universe it would be steamed and that's why the lifecycle of those light black holes is very short. But if the black hole would be close enough the star, it can get very much fuel, and be exist a long time, or as long as the material of the star would feed that thing.
This kind of phenomenon could be very unusual in the universe. But when we are thinking the black holes as the centers of the energy, there is a possibility that nano-size black holes are forming all the time because of the electron showers of magnetars and neutron stars. Forming the black hole would happen simply by increase the mass of the object by pumping the electrons to them, and the electron rays of magnetars are very strong.
But could those black holes danger the life on Earth? The thing is that the life of the small black hole would not take long, but if some ping-pong-ball size black hole would hit the atmosphere of the planet, it would cause a huge explosion. And if it exists only about ten seconds, it can crush the core of Earth, and in the worst-case pull the nucleus of Earth away of the planet.
