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 central star. In the past few years, the central star has brightened considerably, and the response of the reflection nebula to this brightening has been surprisingly complex. While the central star has brightened by a factor of 2 at near-ultraviolet and optical wavelengths, bright dust condensations in the bipolar lobes… Expand

Distinguishing circumstellar from stellar photometric variability in Eta Carinae
The interacting binary Eta Carinae remains one of the most enigmatic massive stars in our Galaxy despite over four centuries of observations. In this work, its light curve from the ultraviolet to theExpand
The sub-arcsecond dusty environment of Eta Carinae
The core of the nebula surrounding Eta Carinae has been observed with the VLT Adaptive Optics system NACO and with the interferometer VLTI/MIDI to constrain spatially and spectrally the warm dustyExpand
Kinematics and Ultraviolet to Infrared Morphology of the Inner Homunculus of η Carinae
We present the first ultraviolet and optical images of η Car and itscircumstellar Homunculus nebula, obtained with the Advanced Camera forSurveys/High Resolution Camera (ACS/HRC) on board the HubbleExpand
Ultraviolet Mg ii emission from fast neutral ejecta around Eta Carinae
We present the first images of the nebula around η Carinae obtained with the Wide Field Camera 3 (WFC3) onboard the Hubble Space Telescope (HST), including an ultraviolet (UV) image in the F280NExpand
The shocking near-infrared spectrum of the Homunculus Nebula surrounding η Carinae
Near-infrared long-slit spectra of the Homunculus Nebula surrounding η Carinae reveal emission from molecular hydrogen for the first time in this object, as well as strong intrinsic [Fe II] emission.Expand
The systemic velocity of Eta Carinae
High-resolution spectra of molecular hydrogen in the Homunculus nebula allow for the first direct measurement of the systemic velocity of η Carinae. Near-infrared long-slit data for H 2 1-0 S(1)Expand
The UV Scattering Halo of the Central Source Associated with η Carinae
We have made an extensive study of the UV spectrum ofCarinae and find that we do not directly observe the star and its wind in the UV. Because of dust along our line of sight, the UV light that weExpand
η Carinae : The 1998 brightening and the smearing-out effect
A comparison of broad-band photometry of the Homunculus (ground-based data) and of broad-band and narrow- band photometry of the central region (HST-based) from 1997 to 2003 reveals that, apart fromExpand
The Purple Haze of η Carinae: Binary-induced Variability?*
Asymmetric variability in ultraviolet images of the Homunculus obtained with the Advanced Camera for Surveys/High Resolution Camera on the Hubble Space Telescope suggests that η Carinae is indeed aExpand
Latitude-dependent Effects in the Stellar Wind of η Carinae
The Homunculus reflection nebula around η Carinae provides a rare opportunity to observe the spectrum of a star from more than one direction. In the case of η Car, the nebula's geometry is known wellExpand

Recurrent X-Ray Emission Variations of η Carinae and the Binary Hypothesis
Recent studies by Damineli and coworkers suggest that the supermassive star η Carinae may have a massive stellar companion, although the dense ejecta surrounding the star make this claim hard to testExpand
The Luminous Blue Variables: Astrophysical Geysers
Some of the most luminous stars have sporadic, violent mass-loss events whose cuases are not understood. These evolved hot stars are called Luminous Blue Variables (LBV's), and their instability mayExpand
