Spectroscopic Monitoring of Metal Lines in Polluted White Dwarfs
Laura K. Rogers, Michael M. Shara, Amy Bonsor +12
The disruption and accretion of planetary material onto white dwarfs is expected to be inherently dynamic and stochastic, potentially driving variability in the accretion rate and…

Metal Polluted White Dwarfs with 21 μm IR excesses from JWST/MIRI: Planets or Dust?
John H. Debes, Sabrina Poulsen, Ashley Messier +13
White dwarfs with metal pollution are caused by the accretion of rocky dust from tidally disrupted minor bodies and are signposts for planetary systems. These minor bodies are pert…
