A Time-Dependent Spectral Analysis of Cassiopeiae

Sean J. Gunderson, David P. Huenemoerder, José M. Torrejón +7

We investigated the temporal and spectral features of Cassiopeiae's X-ray emission within the context of the white dwarf accretion hypothesis. We find that the variabilities pr…

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…
