The publication Nature has shared material in which scientists talked about the first known planet that survived the death of its parent star without changing its orbit.
As part of the study, a team of astronomers from Australia, the United States and France used the method of gravitational microlensing – with its help the closest object distorts the light of a farther star. Thus, they managed to find a planet located 6.5 thousand light years from Earth, two kiloparsecs from the center of the Milky Way. Subsequently, scientists began to search for the parent star of the find, as a result of which it turned out that it is not a main sequence star and a brown dwarf.
“ We were also able to rule out the possibility that it is a neutron star or a black hole. This means that the planet revolves around a dead star – a white dwarf. Thus, we can see what our solar system will look like after the disappearance of the Earth , ”said one of the authors of the scientific work, an employee of the Paris Institute of Astrophysics Jean-Philippe Beaulieu.
