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…

NICER X-ray Observations of Eta Carinae During its Most Recent Periastron Passage

David Espinoza-Galeas, Michael Francis Corcoran, Kenji Hamaguchi +12

We report high-precision X-ray monitoring observations in the 0.4-10 keV band of the luminous, long-period colliding-wind binary Eta Carinae up to and through its most recent X-ray…

Eta Carinae: an evolving view of the central binary, its interacting winds and its foreground ejecta

Theodore R. Gull, D. John Hillier, Henrik Hartman +13

FUV spectra of Eta Car, recorded across two decades with HST/STIS, document multiple changes in resonant lines caused by dissipating extinction in our line of sight. The FUV flux h…

Catching the Butterfly and the Homunculus of Carinae with ALMA

Luis A. Zapata, Laurent Loinard, Manuel Fernández-López +7

The nature and origin of the molecular gas component located in the circumstellar vicinity of Carinae are still far from being completely understood. Here, we present Atacama L…
