The identity of "alien megastructure star". (Tabby's star, WTF star, KIC 8462852)
1) Tabby's star(1) is so-called "blue-sun" or the F-spectral class star.
The identity of the "alien megastructure " what is orbiting the star has been uncovered as the particles, what is orbiting the star following its magnetic power lines, and creating the form, what is looking at the whisk. That means that the structure is natural.
The star is F-type star(2), and the other names of that thing are "WTF-star", "Tabby's Star" or KIC 8462852. The thing what makes this star somehow different than others is that it should blow that form of the asteroids and dust away, or that material should orbit this star in the different form like a disk, what means that the magnetic field of "Tabby's star" is a little bit stronger than usual.
The radiation of the F-type star is stronger than the sun, and the lifetime of those stars is about 2-4 billion years, and the lifetime of the sun is about 10 billion years. The F-type star is a so-called hot sun (or blue sun), which surface temperature is about 6000-7600 kelvin, and the surface temperature of the Sun is 5500 kelvin. So that means that the F-type star would spend it's nuclear fuel faster than the sun.
2) Term alien megastructure can mean naturally formed or artificial form, which is somehow strange.
When we are thinking about the term "alien megastructure" we are facing that this term means extraordinary structures, what can be formed naturally or what can be artificial. It is not officially confirmed case, where the scientists would find the artificial megastructures in the universe, but there are lots of naturally formed unusual and strange things.
And today we are calling also exoplanets and even the planets and moons in our solar system as an "alien worlds" regardless are they habitable, is there living organism or are they only the bites of rock or ice. So term "alien" has faced inflation, and today that means everything, what is different, what we are used to seeing outside at our window. And when we are starting to see this extraordinary form around the star, we might think that there is nothing unusual.
3) Why this whisk-looking thing has been formed around the "Tabby's star"?
Why that whisk-looking shape of the asteroids has been formed around that star? And why the particles, what are coming from that star are not blowing those asteroids away?
But then we can see the form of the group of those particles, and we can ask how they are in the form, what looks like whisk? There must be a very powerful magnetic field of that star because those particles are in that position around the star. That thing is a very unusual detail because there are many stars, what have dust and asteroid disks, but there are not very many cases, where the form of asteroids could be like this.
The reason, why this form of asteroid belts is formed is that the magnetic field of the star would put the asteroids around it in that form. But the thing that makes this kind of thing so interesting is why this kind of asteroid formations are not around stars like the sun?
4) Why the magnetic field of Tabby's star is so powerful, that it can keep this form?
And the second question is, why the radiation pressure from the star would not push the asteroids away, or why they are not in the place like asteroid belts are around other stars? This is a very interesting thing to think about. So that kind of structure is very unusual, and this makes them interesting.
There are known similar structures of the iron bites around the asteroids, what are locating in the Kuiper's Belt, but the asteroid is a little bit different thing than some star. That means that this formation of asteroids in the unusual trajectories is causing interesting ideas.
