FORCASTing the spectroscopic dust properties of the WC+O binary WR137 with SOFIA
Megan J. Peatt, Noel D. Richardson, Peredur M. Williams +5
WR 137 (HD 192641) is a binary system consisting of a carbon-rich Wolf-Rayet star and an Oe companion star in a 13-year orbit. Near periastron, the winds of the two stars collide a…
Eta Carinae: the dissipating occulter is an extended structure
Theodore R. Gull, Henrik Hartman, Mairan Teodoro +10
Previous STIS long-slit observations of Eta Carinae identified numerous absorption features in both the stellar spectrum, and in the adjacent nebular spectra, along our line-of-sig…
The orbital kinematics of eta Carinae over three periastra with a possible detection of the elusive secondary's motion
Emily Strawn, Noel D. Richardson, Anthony F. J. Moffat +14
The binary eta Carinae is the closest example of a very massive star, which may have formed through a merger during its Great Eruption in the mid-nineteenth century. We aimed to co…
Nested Dust Shells around the Wolf-Rayet Binary WR 140 observed with JWST
Ryan M. Lau, Matthew J. Hankins, Yinuo Han +29
Massive colliding-wind binaries that host a Wolf-Rayet (WR) star present a potentially important source of dust and chemical enrichment in the interstellar medium (ISM). However, t…
Changes in the Na D Absorption Components of Carinae Provide Clues on the Location of the Dissipating Central Occulter
Connor S. Pickett, Noel D. Richardson, Theodore Gull +9
The Na D absorption doublet in the spectrum of Carinae is complex, with multiple absorption features associated with the Great Eruption (1840s), the Lesser Eruption (1890s), an…
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…
