I don't know(I don't usually know what happens thousands or millions or billions of years later in my story, just hundreds at most) yet but since this new solar system is important for time periods, it would be best if it remained stable. Of course, if the star or stars get bigger(which if there are multiple stars could lead to the merging of 2 or more stars into 1 or more larger stars which is a drastic event and would likely result in a supernova) this might not be the case, especially for any hot jupiters.
Some scientists think that when the sun becomes a red giant the earth will be engulfed but others think that the earth and all other planets will move their orbits outwards. Others think that the earth won't be engulfed but it will melt just like how it melted in the collision that formed the moon and in the collisions between protoplanets and dwarf planets that eventually formed all 4 rocky planets in our solar system.
Any of these could happen to a hot jupiter's surface but the gas will for certain evaporate if this happens. This means that all that is left is a small rocky planet that used to be the core of a gas giant.
This would most likely mean the end of the dinosaurs and these humans as I know it unless the aliens do a form of gravity assist where the orbit becomes stable and stays in the habitable zone regardless of whether the star will form a white dwarf, a neutron star, or a black hole or if 1 star becomes a white dwarf and accumulates mass ejecting the other star or stars or if they both become white dwarves and eventually merge. This merging of white dwarves could get to temperatures high enough to continue fusion and thus form a star from star remnants if there are enough of them.
