Searching for Massive Remnant Planetary System Hosts with White Dwarf Gaia XP Spectra
Lou Baya Ould Rouis, J. J. Hermes, Pierre Bergeron +5
Remnant planetary systems around massive white dwarfs () are intrinsically rare and remain poorly characterized. As the evolutionary endpoints of i…
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…
Picture an Astronomer: Best Practices for Retaining Talent in Astrophysics
Ava Polzin, Katherine E. Whitaker, C. Megan Urry +85
Women are consistently underrepresented in astrophysics yet are simultaneously subject to disproportionate attrition at every career stage. This disparity between demonstrated effi…
Using 3.4-m Variability towards White Dwarfs as a Signpost of Remnant Planetary Systems
Joseph A. Guidry, J. J. Hermes, Kishalay De +3
Roughly 2% of white dwarfs harbor planetary debris disks detectable via infrared excesses, but only a few percent of these disks show a gaseous component, distinguished by their do…
