They found a Neutron star inside a Red Giant

Wow, I never contemplated this possibility.

Makes some sense in a way, giant inflates and this deorbit the neuron star.

The other option is that the neuron star eats all the star atmosphere who I guess happen if the distance between them are larger and I thought this always happened.

Wonder how this end, the neuron star would spiral inward and should grow, proably becomes a black hole at one point and we get a black hole inside a star.

Sounds even more weird.

you get a black hole inside a star, bye bye star.

A black hole inside a star? That wouldn't last very long in that state. Most likely, it'd eat the star, turning into a bigger black hole in the process.

Though, at this point, I'm starting to think of entire solar systems orbiting another bigger solar system.

orbits get funky towards the galactic center. though its not the kind of place you would want to call home.

Neutron star != black hole

Neutron star != black hole

Carefully reread the thread and comment again

Castor, Gliese 667...

Castor, Gliese 667...

We found several already? This universe is startlingly remarkable.

[SargeRho]

Yep. I guess you could count Alpha Centauri AB as well. The two stars orbit eachother at sufficient distance to allow planetary systems on both.

That happens then a black hole starts anyway, and yes the star blows up, dumping mass into a black hole released lot of energy.

Actually, this is one of the primary ideas behind supermassive black hole formation.

Those holes are so massive that there is no known way in which they can consume so much mass within the lifetime of the universe. They're simply too heavy and the intake of material is limited by the small size of the hole.

The main idea behind their formation is that shortly after the Big Bang the first stars were so massive that their cores collapsed into a black hole. But, unlike our stars they were massive enough to not go supernova. So you had a gigantic star getting eaten by a black hole from the inside out. But because the star was so gigantic it could last in this state for millions of years, force feeding the hole until it was big enough to grow to a supermassive black hole on its own.

The question is how stable this system is? How much time can last?

1 millon years? less... or a lot more?

Clearly a lot of matter would fall into the neutron star, but maybe not too much becouse the neutron star also push mater away with the 2 jet beams.

And what happen with the normal star fussion? Decrease or increase?

Eventually the neutron star would become a black hole, from this point I dont know how much time would last.
