Using CHIRON Spectroscopy to Test the Hypothesis of a Precessing Orbit for the WN4 star EZ CMa
Krister DG. Barclay, Sophie Rosu, Noel D. Richardson +4
The bright WN4 star EZ CMa exhibits a 3.77 day periodicity in photometry, spectroscopy, and polarimetry but the variations in the measurements are not strictly phase-locked, exhibi…
Modeling Variable Linear Polarization Produced by Co-Rotating Interaction Regions (CIRs) Across Optical Recombination Lines of Wolf-Rayet Stars
R Ignace, J E Bjorkman, A-N Chene +5
Massive star winds are structured both stochastically ("clumps") and often coherently (Co-rotation Interaction Regions, or CIRs). Evidence for CIRs threading the winds of Wolf-Raye…
Roman Early-Definition Astrophysics Survey Opportunity: Galactic Roman Infrared Plane Survey (GRIPS)
Roberta Paladini, Catherine Zucker, Robert Benjamin +67
A wide-field near-infrared survey of the Galactic disk and bulge/bar(s) is supported by a large representation of the community of Galactic astronomers. The combination of sensitiv…
Accreting Black Holes Skewing and Bending the Optical Emission from Massive Wolf-Rayet Companions -- A Case Study of IC10 X-1
Sayantan Bhattacharya, Dimitris M. Christodoulou, Andre-Nicolas Chene +3
We present a statistical analysis of the He ii 4686 emission line in the spectra of the black hole and Wolf-Rayet (WR) star of the high-mass X-ray binary IC10 X-1. This line is vis…
Probing the Stellar Wind of the Wolf-Rayet Star in IC 10 X-1
Sayantan Bhattacharya, Silas G. T. Laycock, Andre-Nicolas Chene +5
IC 10 X-1 is an eclipsing high mass X-ray binary (HMXB) containing a stellar-mass black hole (BH) and a Wolf-Rayet (WR) donor star with an orbital period of P = 34.9 hr. This binar…
A high-mass X-ray binary descended from an ultra-stripped supernova
Noel D. Richardson, Clarissa Pavao, Jan J. Eldridge +6
Ultra-stripped supernovae are different from other terminal explosions of massive stars, as they show little or no ejecta from the actual supernova event. They are thought to occur…
