Nesta tese foi feito um estudo dos eventos cíclicos em Carinae em diversas faixas
espectrais. A presença de um buraco na região polar do Homúnculo foi confirmada pelos …

In this thesis, a multi-wavelength study on the cyclic events of η Carinae was performed. The
presence of a hole in the polar region of the Homunculus was confirmed by the velocity …

Neste trabalho apresentamos uma análise das observaçoes das linhas de recombinaçao
em ondas milimétricas (H30α, H35α, H40α e H50β) na direçao de η Carinae obtidas, entre …

The 6307A emission line in the spectrum of Eta Car (Martin et al. 2006) is blue-shifted [S III]
6313A emission originating from the outer wind structures of the massive binary system. We …

Nesta dissertação são apresentados os resultados obtidos da espectroscopia de campo
integral da nebulosa do Homúnculo. As observações foram feitas na banda J, no intervalo …

The Historical Evidence for the 5.52-Year Cycle Page 1 – Eta Carinae at the Millennium ASP
Conference Series, Vol. 179, 1999 JA Morse, RM Humphreys, and A. Damineli, eds. The …

The periodic minima in η Carinae are now well defined and interpreted as due to periastron
passage of two massive stars in a very eccentric orbit. Different mechanisms have been …

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 …

Abstract For the Cepheid l Carinae, with a pulsation period of 35.5 days, we have studied
the emission-line fluxes as a function of pulsational phase in order to find out whether we …

Even after more than a century of intensive studies, little is known about η Carinae as a star.
Its high luminosity and the observed episodes of mass ejection suggest that it is a LBV …
