Mapping Wolf-Rayet winds with spectro-interferometry I. Detection of multiple co-rotating interaction regions in WR 6

K. Deshmukh, A. -N. Chené, A. J. Frost +8

WR 6 is the prototype for periodic variability due to large-scale wind structures in Wolf-Rayet (WR) stars, showing a consistent periodicity of 3.76 d in photometry, spectroscopy,…

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…

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…

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…
