The qWR star HD 45166. II. Fundamental stellar parameters and evidence of a latitude-dependent wind
J. H. Groh, A. S. Oliveira, J. E. Steiner
The enigmatic object HD 45166 is a qWR star in a binary system with an orbital period of 1.596 day, and presents a rich emission-line spectrum in addition to absorption lines from…
Near-infrared integral field spectroscopy of the Homunculus nebula around Eta Carinae using Gemini/CIRPASS
M. Teodoro, A. Damineli, R. G. Sharp +2
This work presents the first integral field spectroscopy of the Homunculus nebula around Eta Carinae in the near-infrared spectral region (J band). We confirmed the presence of a h…
A multispectral view of the periodic events in eta Carinae
A. Damineli, D. J. Hillier, M. F. Corcoran +13
A full description of the 5.5-yr low excitation events in Eta Carinae is presented. We show that they are not as simple and brief as previously thought, but a combination of two co…
LBVs and the nature of the S Dor cycles: the case of AG Carinae
J. H. Groh, A. Damineli, D. J. Hillier
We present the results of a detailed spectroscopic analysis of 20 years of observations of AG Carinae using the radiative transfer code CMFGEN. Among the conclusions of this work,…
Spectral atlas of massive stars around He I 10830 A
J. H. Groh, A. Damineli, F. Jablonski
We present a digital atlas of peculiar, high-luminosity massive stars in the near-infrared region (10470-11000 A) at medium resolution (R~7000). The spectra are centered around He…
Detection of additional Wolf-Rayet stars in the starburst cluster Westerlund 1 with SOAR
J. H. Groh, A. Damineli, M. Teodoro +1
We report the detection of 3 additional Wolf-Rayet stars in the young cluster Westerlund 1. They were selected as emission-line star candidates based on 1 micron narrow-band imagin…
