Ultraviolet Spectropolarimetry with Polstar: Massive Star Binary Colliding Winds
Nicole St-Louis, Kenneth Gayley, Desmond John Hillier +13
As sources of chemical enrichment, ionizing radiation and energetic feedback, massive stars drive the ecology of their host galaxies despite their relative rarity, additionally to…
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…
Uncovering astrometric black hole binaries with massive main-sequence companions with Gaia
S. Janssens, T. Shenar, H. Sana +6
The hunt for compact objects is on. Rarely seen massive binaries with a compact object are a crucial phase in the evolution towards compact object mergers. In Gaia data release 3 (…
Ultraviolet Spectropolarimetry:Conservative and Nonconservative Mass Transfer in OB Interacting Binaries
Geraldine J. Peters, Ken Gayley, Richard Ignace +11
One objective of the Polstar spectropolarimetry mission is to characterize the degree of nonconservative mass transfer that occurs at various stages of binary evolution, from the i…
The Tarantula Massive Binary Monitoring V. R 144: a wind-eclipsing binary with a total mass > 140 Msun
T. Shenar, H. Sana, P. Marchant +21
R 144 is the visually brightest WR star in the Large Magellanic Cloud (LMC). R 144 was reported to be a binary, making it potentially the most massive binary thus observed. We perf…
The excess of cool supergiants from contemporary stellar evolution models defies the metallicity-independent Humphreys-Davidson limit
Avishai Gilkis, Tomer Shenar, Varsha Ramachandran +5
The Humphreys-Davidson (HD) limit empirically defines a region of high luminosities (log L > 5.5) and low effective temperatures (T < 20kK) on the Hertzsprung-Russell Diagram in wh…
The First Dynamical Mass Determination of a Nitrogen-rich Wolf-Rayet Star using a Combined Visual and Spectroscopic Orbit
Noel D. Richardson, Laura Lee, Gail Schaefer +11
We present the first visual orbit for the nitrogen-rich Wolf-Rayet binary, WR 133 (WN5o + O9I) based on observations made with the CHARA Array and the MIRC-X combiner. This orbit r…
