Stellar evolution models predict that the mass-loss on the AGB will be pulsed; furthermore, observations indicate that the bulk of the mass-loss occurs on the AGB. In this case, if the progenitors of the white dwarfs had remnants of planetary formation like the Sun’s Oort cloud or the Kuiper Belt and a planet lying within that cloud or nearby, we find that up to 2 per cent of the planetesimals will fall either into planet-crossing orbits or into chaotic regions after the mass-loss, depending on the location and mass of the planet (from Mars to Neptune). This yields a sufficient mass of comets that can be scattered towards the star, form a debris disc and pollute the atmosphere."}],"status":"public","intvolume":"       469","date_updated":"2024-04-08T07:05:00Z","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.1702.07682","open_access":"1"}],"extern":"1","volume":469,"article_type":"original","external_id":{"arxiv":["1702.07682"]}}
