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

Sean J. Gunderson, Kenneth G. Gayley, David P. Huenemoerder +2

We fit the high resolution \textit{Chandra} X-ray spectra of the O supergiant Puppis using the variable boundary condition (VBC) line model to test the stability of its mass-lo…

Testing the Reliability of X-rays as a Tool for Constraining Mass-loss Rates of Hot Stars

Sean J. Gunderson, Kenneth G. Gayley, Pragati Pradhan +2

We fit a new line shape model to \textit{Chandra} X-ray spectra of the O supergiant Puppis to test the robustness of mass-loss rates derived from X-ray wind line profiles again…

Correlated X-ray and optical variability in the O-type supergiant zeta Puppis

Joy S. Nichols, Yael Naze, David P. Huenemoerder +11

Analysis of the recent long exposure Chandra X-ray observation of the early-type O star zeta Pup shows clear variability with a period previously reported in optical photometric st…

A Deep Exposure in High Resolution X-Rays Reveals the Hottest Plasma in the Puppis Wind

David P. Huenemoerder, Richard Ignace, Nathan A. Miller +9

We have obtained a very deep exposure (813 ks) of Puppis (O4 supergiant) with the Chandra/HETG Spectrometer. Here we report on analysis of the 1-9 Å region, especially well su…

X-ray Emission from Magnetically Torqued Disks of Oe/Be Stars

Q. Li, J. P. Cassinelli, J. C. Brown +2

We focus attention on the Oe/Be stars to test the concept that the disks of these stars form by magnetic channeling of wind material toward the equator. Calculations are made of th…
