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…
The SPACE Program II: No discernible spectral features in the transmission spectrum of the sub-Neptune HD 191939 b observed with HST/WFC3
Cyril Gapp, Lorena Acuña-Aguirre, Reza Ashtari +17
The atmospheres of sub-Neptunes provide a window into their internal structure and history, shedding light on the origin of this common, but enigmatic, class of exoplanets. However…
Direct detections of white dwarfs in four WD+dM post-common envelope binaries within 20 pc
Mairi W. O'Brien, David J. Wilson, Pier-Emmanuel Tremblay +5
The paper reports the first direct spectroscopic detections of white dwarf companions in four nearby post‑common envelope binaries, using HST near‑UV observations to determine thei…
A Critical UV Legacy: A Hubble Roadmap for HWO Science Readiness
Sarah Peacock, Aiden S. Zelakewicz, Lisa Kaltenegger +14
The Habitable Worlds Observatory (HWO) will provide the first opportunity to directly image and spectrally characterize terrestrial exoplanets in the habitable zones of nearby star…
The unique ability of the Hubble Space Telescope to characterize young exoplanet environments
Keighley E. Rockcliffe, Allison Youngblood, Kevin France +10
The chemical and mass evolution of exoplanet atmospheres is shaped by their specific X-ray through ultraviolet (5 - 3200 Angstroms) irradiance history. X-ray and EUV (5 - 911 Angst…
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…
