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 longslit data for H2 1-0 S(1) λ21218 obtained with the Phoenix spectrometer on the Gemini South telescope give Vsys=−8.1±1 km s −1 (heliocentric), or VLSR=−19.7±1 km s , from the average of the near and far sides of the Homunculus. Th...
متن کاملComparing Eta Carinae with the Red Rectangle
I compare the structures of the bipolar nebulae around the massive binary system η Carinae and around the low mass binary system HD 44179. While η Carinae is on its way to become a supernova, the Red Rectangle is on its way to form a planetary nebula. Despite the two orders of magnitude difference in mass, these two systems show several similarities, both in the properties of the stellar binary...
متن کاملEta Carinae across the 2003.5 Minimum: Analysis in the visible and near infrared spectral region
We present analysis of the visible through near infrared spectrum of ηCar and its ejecta obtained during the ”ηCar Campaign with the Ultraviolet Visual Echelle Spectrograph (UVES) at the ESO Very Large Telescope (VLT)”. This is a part of larger effort to present a complete ηCar spectrum, and extends the previously presented analyses with the Hubble Space Telescope/Space Telescope Imaging Spectr...
متن کاملAccretion onto the Companion of Eta Carinae during the Spectroscopic Event. v. the Infrared Decline
We propose that the decline in the near-IR flux from the massive binary system η Carinae during the spectroscopic event might be explained by accreted mass that absorbs the radiation from the secondary star, and by that reduces the heating of the dust that is responsible for the near-IR emission. This binary system has an orbital period of 2024 days and eccentricity of e ≃ 0.9. The emission in ...
متن کاملEta Carinae and Other Luminous Blue Variables
Luminous Blue Variables (LBVs) are believed to be evolved, extremely massive stars close to the Eddington Limit and hence prone to bouts of large-scale, unstable mass loss. I discuss current understanding of the evolutionary state of these objects, the role duplicity may play and known physical characteristics of these stars using the X-ray luminous LBVs Eta Carinae and HD 5980 as test cases.
