Alpha Centauri Bb Archives

Gas column density of the Phantom hydrodynamical simulation of the circumstellar discs in the binary Alpha Centauri. The stars start at apoastron: A is in the top left corner, and B is in the bottom right corner. From left to right and top to bottom, we show the system at different evolutionary stages: 0, 0.5, 1, 1.5, 2.0, 2.5, 3, and 5 Pb , where Pb is a binary orbital period. The red dots represent the stars of Alpha Centauri. -- astro-ph.EP
