Metal Polluted White Dwarfs with 21 μm IR excesses from JWST/MIRI: Planets or Dust?
URL https://arxiv.org/pdf/2506.21224.pdf Stage Normal Science / Model Drift Paradigm framing The current paradigm is that metal pollution in white dwarfs arises from the accretion of planetary debris. This is supported by spectroscopic observations and abundance patterns consistent with rocky material. The paradigm includes theoretical models of tidal disruption events and planetary system evolution post-main sequence. […]
