Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The paper summarizes 70 science cases for the proposed NASA Habitable Worlds Observatory, outlining the observational needs across four scientific pillars and detailing required ca…
I Can Do It With A Broken Planetesimal: Characterising the planetary debris in heavily polluted cool white dwarfs
Anna-Maria Cutolo, Boris T. Gänsicke, Boris T. Gänsicke +8
The paper analyzes four cool, metal‑polluted hydrogen‑atmosphere white dwarfs using X‑shooter spectra to determine their atmospheric parameters and the composition of accreted plan…
White dwarfs within 13 pc: Insights from ultraviolet spectroscopy
Mairi W. O'Brien, Pier-Emmanuel Tremblay, Boris T. Gaensicke +9
We present a comprehensive multi-wavelength spectroscopic and photometric analysis of the 44 confirmed white dwarfs within 13 pc of the Sun. Combining flux-calibrated ultraviolet (…
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…
Exogeological inferences from white dwarf pollutants: the impact of stellar physics
Andrew M. Buchan, Pier-Emmanuel Tremblay, Antoine Bédard +2
Many white dwarfs have accreted material from their own planetary systems. These objects can be used to infer the composition of exoplanetary material and identify evidence for key…
White dwarfs as probes of extrasolar planet compositions and fundamental astrophysics
Siyi Xu, Martin Barstow, Andy Buchan +2
White dwarfs represent the most common end stage of stellar evolution and are important for a range of astrophysical questions. The high-resolution ultraviolet spectroscopic capabi…
