Spectropolarimetry for Discerning Geometry and Structure in Circumstellar Media of Hot Massive Stars
Richard Ignace, Kenneth Gayley, Roberto Casini +3
Spectropolarimetric techniques are a mainstay of astrophysical inquiry, ranging from Solar System objects to the Cosmic Background Radiation. This review highlights applications of…
Deriving X-ray Line Profiles for Massive-Star Winds from Momentum-Conserving Dynamical Working Surface Solutions
Sean J. Gunderson, Kenneth G. Gayley
We present a general procedure for deriving a line profile model for massive star X-ray spectra that captures the dynamics of the wind more directly. The basis of the model is the…
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…
Ultraviolet Spectropolarimetry With Polstar: Using Polstar to test Magnetospheric Mass-loss Quenching
M. E. Shultz, R. Casini, M. C. M. Cheung +17
Polstar is a proposed NASA MIDEX space telescope that will provide high-resolution, simultaneous full-Stokes spectropolarimetry in the far ultraviolet, together with low-resolution…
UV Spectropolarimetry with Polstar: Massive Star Binary Colliding Winds
Nicole St-Louis, Kenneth Gayley, D. John Hillier +13
The winds of massive stars are important for their direct impact on the interstellar medium, and for their influence on the final state of a star prior to it exploding as a superno…
Ultraviolet Spectropolarimetric Diagnostics of Hot Star Magnetospheres
Asif ud-Doula, M. C. M. Cheung, A. David-Uraz +11
Several space missions and instruments for UV spectropolarimetry are in preparation, such as the proposed NASA MIDEX Polstar project, the proposed ESA M mission Arago, and the Poll…
