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…
Modeling of Rayleigh Scattering and Interstellar Polarization for Evolved Late-Type Stars
R Ignace, C Erba, K DeGennaro +1
Evolved late-type stars are frequently identified as photometric and spectroscopic variables, such as Mira-type or semi-regular variable objects. These stars can also be polarimetr…
Polarization from Rapidly Rotating Massive Stars
J. Patrick Harrington, Richard Ignace, Kenneth G. Gayley
Stellar rotation has long been recognized as important to the evolution of stars, by virtue of the chemical mixing it can induce and how it interacts with binary mass transfer. Bin…
Chandra/HETG and NuSTAR Observations of V750 Ara, a Cas-type Star
David P. Huenemoerder, Sean J. Gunderson, Richard Ignace +6
We present 197 ks HETG and 95 ks NuSTAR spectra of the Cas-type object V750 Ara. The high-resolution X-ray spectra show that the target is similar to other objects of this cl…
A Multiwavelength View of Oph I: Resolving the X-ray Source Between A and B
Sean J. Gunderson, Jackson Codd, Walter W. Golay +12
We present a multiwavelength analysis of the central stellar pair of Oph, components A and B. Using recent high-resolution \textit{Chandra X-ray Observatory} observations, we d…
The Second Stellar Spectrum: Rotating hot massive star linear spectropolarimetry with the Ohman Effect
J. Patrick Harrington, R. Ignace, K. G. Gayley +1
To understand better the polarized radiative transfer near the surface of rotating massive stars that remain nearly spherically symmetric, we use plane-parallel stellar atmosphere…
