ABSTRACT I have discovered spectroscopic variations correlated with the photometric near-
infrared (NIR) light curve in &eegr; Carinae. The fading of the high-excitation lines is …

Near-infrared, JHKL, photometry of η Car is reported covering the period 2000–2004. This
includes the 2003 shell event which was the subject of an international multiwavelength …

A full description of the 5.5-yr low excitation events in η Carinae is presented. We show that
they are not as simple and brief as previously thought, but a combination of two components …

Astrometric Analysis of the Homunculus of eta Carinae With the Hubble Space Tele ADS Classic
is now deprecated. It will be completely retired in October 2019. This page will automatically …

Extensive spectral observations of η Carinae over the last cycle, and particularly around the
2003.5 low-excitation event, have been obtained. The variability of both narrow and broad …

We report the recovery of a spectroscopic event in η Carinae in 1997/1998 after a prediction
by Damineli in 1996. A true periodicity with P= 2020±5 days (0.2% uncertainty) is obtained …

Damineli et al.(1997)[NewA, 2, 107] have recently proposed a specific binary model for η
Carinae. It is based on wavelength shifts in hydrogen and helium emission lines, and may …

High-resolution 6450-24500 A spectra of eta Carinae ADS Classic is now deprecated. It will be
completely retired in October 2019. This page will automatically redirect to the new ADS interface …

Abstract Infrared (1.25–3.5 μm) light curves of η Carinae covering the last 20 yr are
presented and discussed. Three features are clearly seen in these data. First there is an …

We have extensively monitored the Luminous Blue Variable AG Car (HD 94910)
spectroscopically. Our data cover the years 1989 to 1999. In this period, the star underwent …
