In order to study the distribution of gas and ionizing radiation around η Car and their
implications for its likely companion star, we have examined high-excitation emission lines …

Abstract We present Hubble Space Telescope (HST) Space Telescope Imaging
Spectrograph (STIS) high-resolution near-ultraviolet (NUV) spectra of η Car's central source …

We describe and analyze Hubble Space Telescope (HST) observations of transient
emission near 4680 Å in η Car, reported earlier by Steiner & Damineli. If, as seems …

Long-slit spectroscopic observations of η Carinae and its Homunculus have recently been
obtained using STIS on the Hubble Space Telescope (HST). We have extracted the …

We report the results of an observing campaign on η Car around the 2003 X-ray minimum,
mainly using the XMM-Newton observatory. These are the first spatially resolved X-ray …

We have analyzed high spatial, moderate spectral resolution observations of η Carinae (η
Car) obtained with the STIS from 1998.0 to 2004.3. The data were obtained at discrete times …

We report on Hα spectroscopy of the 2009.0 spectroscopic event of η Carinae collected via
SMARTS observations using the Cerro Tololo Interamerican Observatory 1.5 m telescope …

ABSTRACT Hubble Space Telescope (HST) continuum and emission-line images of η
Carinae obtained with the Planetary Camera (PC) of the Wide Field Planetary Camera 2 …

Multiepoch HST/WFPC2 images of η Carinae are used to investigate the relationship
between the photometric variability of the circumstellar nebula and the variability of the …

We report the detection of a hot companion of η Carinae using high-resolution spectra (905-
1180 Å) obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite …
