Sensitivity of Dragonfly Afterbody Radiation to Chemical Kinetic Parameters and Freestream Methane

Michael C. Sands, Ross S. Chaudhry, Audrey Gaymann, N. A. Miller et autres

Dragonfly is a NASA mission that aims to deliver a rotorcraft to explore the near-surface environment of Saturn's moon Titan. The flow around the Dragonfly capsule entering the Titan atmosphere is simulated and used to determine the associated radiation. The goal of …

Observed epochal variations in X-ray lines from the O supergiant ζ Puppis do not require substantial changes in the wind mass flux

Sean J. Gunderson, K. G. Gayley, David P. Huenemoerder, Pragati Pradhan et autres

ABSTRACT We fit the high-resolution Chandra X-ray spectra of the O supergiant ζ Puppis using the variable boundary condition (VBC) line model to test the stability of its mass-loss rate between two epochs of observation: 2000 March and 2018 July – 2019 …

Testing the reliability of X-rays as a tool for constraining mass-loss rates of hot stars

Sean J. Gunderson, K. G. Gayley, Pragati Pradhan, David P. Huenemoerder et autres

ABSTRACT We fit a new line shape model to Chandra X-ray spectra of the O supergiant ζ Puppis to test the robustness of mass-loss rates derived from X-ray wind line profiles against different assumed heating models. Our goal is to track the …

Probing the Photosphere/Wind Connection in Hot Stars with a Long-Exposure Chandra Observation of Zeta Puppis: X-Ray and Optical Variability

N. A. Miller, Joy S. Nichols, Yaël Nazé, David P. Huenemoerder et autres

Many previous studies of ζ Puppis (O4I(n)fp) at a variety of wave bands have reported periodic variability for this star. These studies found periods ranging from less than a day up to approximately 5 days, with much recent interest centered on the …
