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…

On the changes in the physical properties of the ionized region around the Weigelt structures in Eta Carinae over the 5.54-yr spectroscopic cycle

M. Teodoro, T. R. Gull, M. A. Bautista +3

We present HST/STIS observations and analysis of two prominent nebular structures around the central source of Eta Carinae, the knots C and D. The former is brighter than the latte…

VLTI-AMBER velocity-resolved aperture-synthesis imaging of Eta Carinae with a spectral resolution of 12000. Studies of the primary star wind and innermost wind-wind collision

G. Weigelt, K. -H. Hofmann, D. Schertl +26

Context. The mass loss from massive stars is not understood well. Eta Car is a unique object for studying the massive stellar wind during the LBV phase. It is also an eccentric bin…

The fossil wind structures of Eta Carinae: changes across on 5.54-year cycle

Theodore R. Gull, Thomas I. Madura, Mairan Teodoro +11

Eta Carinae, the closest, active, massive binary containing a highly unstable LBV, exhibits expanding, compressed wind shells, seen in emission, that are spatially and spectrally r…

Extinction law in the range 0.4-4.8 m and the 8620 DIB towards the stellar cluster Westerlund 1

Augusto Damineli, Leonardo A. Almeida, Robert D. Blum +4

The young stellar cluster Westerlund 1 (Wd 1: =339.6, b=0.4) is one of the most massive in the local Universe, but accurate parameters are pending on better d…
