Ultraviolet Spectropolarimetry with Polstar: Massive Star Binary Colliding Winds
Nicole St-Louis, Kenneth Gayley, Desmond John Hillier +13
As sources of chemical enrichment, ionizing radiation and energetic feedback, massive stars drive the ecology of their host galaxies despite their relative rarity, additionally to…
Spectropolarimetry for Discerning Geometry and Structure in Circumstellar Media of Hot Massive Stars
Richard Ignace, Kenneth Gayley, Roberto Casini +3
Spectropolarimetric techniques are a mainstay of astrophysical inquiry, ranging from Solar System objects to the Cosmic Background Radiation. This review highlights applications of…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Efficiency of viscous angular momentum transport in dissipating Be binaries
Peter Quigley, Carol E. Jones, Kenneth Gayley +9
Angular momentum transport is a fundamental process shaping the structure, evolution, and lifespans of stars and disks across a wide range of astrophysical systems. Be stars offer…
The Physical Basis of the Lx-Lbol Empirical Law for O-star X-rays
Stan Owocki, Jon Sundqvist, David Cohen +1
X-ray satellites since Einstein have empirically established that the X-ray luminosity from single O-stars scales linearly with bolometric luminosity, Lx ~ 10^-7 Lbol. But straight…
The prototype colliding-wind pinwheel WR 104
Peter Tuthill, John Monnier, Nicholas Lawrance +3
Results from the most extensive study of the time-evolving dust structure around the prototype "Pinwheel" nebula WR 104 are presented. Encompassing 11 epochs in three near-infrared…
