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…

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…

Spectroscopic Signatures of the Vanishing Natural Coronagraph of eta Carinae

A. Damineli, F. Navarete, D. J. Hillier +7

Eta Carinae is a massive interacting binary system shrouded in a complex circumstellar environment whose evolution is the source of the long-term brightening observed during the la…
