PEWDD: A database of white dwarfs enriched by exo-planetary material
Jamie Williams, Boris Gaensicke, Andrew Swan +4
We present the Planetary Enriched White Dwarf Database (PEWDD), a collection of published photospheric abundances of white dwarfs accreting planetary debris alongside additional in…
White dwarf planetary systems in the ultraviolet
Jamie Williams, Amy Bonsor, Boris Gänsicke +9
Almost every known planet host will evolve into a white dwarf, and the surviving planetary material will continue to orbit this stellar remnant. Asteroids perturbed onto star-grazi…
From Hubble to HWO: Bridging the Frontier of White Dwarf Exoplanet Science
Laura K. Rogers, Siyi Xu, Martin Barstow +20
White dwarf stars, the endpoint of stellar evolution for 97% of stars in our Milky Way, offer a unique and powerful window into the bulk elemental composition of rocky exoplanetary…
The Future of Evolved Planetary Systems
Roberto Raddi, Anna F. Pala, Alberto Rebassa-Mansergas +19
Understanding the formation, evolution, and chemical diversity of exoplanets are now central areas of astrophysics research. White dwarfs provide a uniquely sensitive laboratory fo…
An observational overview of white dwarf stars
Ingrid Pelisoli, Jamie Williams
White dwarf stars are the most common final stage of stellar evolution. Since the serendipitous discovery of the first white dwarf by William Herschel and the first physical models…
