The Aromatic Infrared Bands around the Wolf-Rayet Binary WR140 Revealed by JWST
Kotomi Taniguchi, Ryan M. Lau, Takashi Onaka +12
We have analyzed the aromatic infrared bands (AIBs) in the 6-11.2 m range around the Wolf-Rayet binary WR140 (d=1.64 kpc) obtained with the James Webb Space Telescope (JWST) Mid…
Carbon-rich dust injected into the interstellar medium by Galactic WC binaries survives for hundreds of years
Noel D. Richardson, Micaela Henson, Emma P. Lieb +23
Some carbon-rich Wolf-Rayet stars (WC stars) show an infrared excess from dust emission. Dust forms in the collision of the WC wind with a companion star's wind. As this dust is ca…
A First Look with JWST Aperture Masking Interferometry (AMI): Resolving Circumstellar Dust around the Wolf-Rayet Binary WR 137 beyond the Rayleigh Limit
Ryan M. Lau, Matthew J. Hankins, Joel Sanchez-Bermudez +20
We present infrared aperture masking interferometry (AMI) observations of newly formed dust from the colliding winds of the massive binary system Wolf-Rayet (WR) 137 with JWST usin…
Carinae's Dusty Homunculus Nebula from Near-Infrared to Submillimeter Wavelengths: Mass, Composition, and Evidence for Fading Opacity
Patrick W. Morris, Theodore R. Gull, D. John Hillier +5
Infrared observations of the dusty, massive Homunculus Nebula around the luminous blue variable Carinae are crucial to characterize the mass-loss history and help constrain the…
3D hydrodynamical and radiative transfer modeling of Eta Carinae's colliding winds
Thomas I. Madura, Nicola Clementel, Theodore R. Gull +3
We present results of full 3D hydrodynamical and radiative transfer simulations of the colliding stellar winds in the massive binary system Eta Carinae. We accomplish this by apply…
The Optical Wind Line Variability of Carinae During the 2009.0 Event
Noel D. Richardson, Douglas R. Gies, Theodore R. Gull +2
We report on high-resolution spectroscopy of the 2009.0 spectroscopic event of Carinae collected via SMARTS observations using the CTIO 1.5 m telescope and echelle spectrograph…
