Ultraviolet Spectropolarimetry with Polstar: Clumping and Mass-loss Rate Corrections
Ken Gayley, Jorick S. Vink, Asif ud-Doula +13
The most massive stars are thought to lose a significant fraction of their mass in a steady wind during the main-sequence and blue supergiant phases. This in turn sets the stage fo…
Binary-object spectral-synthesis in 3D (BOSS-3D) -- Modelling H-alpha emission in the enigmatic multiple system LB-1
L. Hennicker, N. D. Kee, T. Shenar +5
Context: To quantitatively decode the information stored within an observed spectrum, detailed modelling of the physical state and accurate radiative transfer solution schemes are…
Simulations of the line-driven instability in magnetic hot star winds
F. A. Driessen, N. D. Kee, J. O. Sundqvist
Line-driven winds of hot, luminous stars are intrinsically unstable due to the line-deshadowing instability (LDI). In non-magnetic hot stars, the LDI leads to the formation of an i…
Upper Mass-Loss Limits and Clumping in the Intermediate and Outer Wind Regions of OB stars
M. M. Rubio-Díez, J. O. Sundqvist, F. Najarro +4
We probe the radial clumping stratification of OB stars in the intermediate and outer wind regions (r>~2 R*) to derive upper limits for mass-loss rates, and compare to current mass…
Empirical mass-loss rates and clumping properties of Galactic early-type O supergiants
C. Hawcroft, H. Sana, L. Mahy +7
We investigate the impact of optically thick clumping on stellar wind diagnostics in O supergiants and constrain wind parameters associated with porosity in velocity space. This is…
Ultraviolet Line Profiles of Slowly Rotating Massive Star Winds Using the "Analytic Dynamical Magnetosphere" Formalism
C. Erba, A. David-Uraz, V. Petit +6
Recent large-scale spectropolarimetric surveys have established that a small but significant percentage of massive stars host stable, surface dipolar magnetic fields with strengths…
