The Roman Space Telescope as a Planetary Defense Asset
Bryan J. Holler, Richard G. Cosentino, William C. Schultz +5
NASA's Nancy Grace Roman Space Telescope, slated to launch in October 2026, will serve a critical role in the characterization and threat assessment of near-Earth Objects (NEOs), t…
Turbulence Supported Massive Star Envelopes
William Schultz, Lars Bildsten, Yan-Fei Jiang
The outer envelopes of massive () stars exhibit large increases in opacities from forests of lines and ionization transitions (particularly from iron and hel…
Synthesizing Spectra from 3D Radiation Hydrodynamic Models of Massive Stars Using Monte Carlo Radiation Transport
William C. Schultz, Benny T. H. Tsang, Lars Bildsten +1
Observations indicate that turbulent motions are present on most massive star surfaces. Starting from the observed phenomena of spectral lines with widths much larger than thermal…
Stochastic Low Frequency Variability in 3-Dimensional Radiation Hydrodynamical Models of Massive Star Envelopes
William C. Schultz, Lars Bildsten, Yan-Fei Jiang
Increasing main sequence stellar luminosity with stellar mass leads to the eventual dominance of radiation pressure in stellar envelope hydrostatic balance. As the luminosity appro…
Convectively Driven Three Dimensional Turbulence in Massive Star Envelopes: I. A 1D Implementation of Diffusive Radiative Transport
William Schultz, Lars Bildsten, Yan-Fei Jiang
Massive (M) stars exhibit luminosities that are near the Eddington-limit for electron scattering causing the increase in opacity associated with iron at $T\appro…
Deep Neural Network Classifier for Variable Stars with Novelty Detection Capability
Benny T. -H. Tsang, William C. Schultz
Common variable star classifiers are built only with the goal of producing the correct class labels, leaving much of the multi-task capability of deep neural networks unexplored. W…
