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…

Discovery of extraordinary X-ray emission from magnetospheric interaction in the unique binary stellar system Lupi

B. Das, V. Petit, Y. Nazé +12

We report detailed X-ray observations of the unique binary system Lupi, the only known short-period binary consisting of two magnetic early-type stars. The components have comp…

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…
