We reconstruct the evolution of η Car in the last two centuries under the assumption that the two 19th century eruptions were triggered by periastron passages and through this reconstruction constrain the binary parameters. The beginning of the lesser eruption (LE) at the end of the 19th century occurred when the system was very close to periastron passage, suggesting that the secondary triggered the LE. We assume that the 1838-1858 great eruption (GE) was triggered by a periastron passage as… Expand

Was the nineteenth century giant eruption of Eta Carinae a merger event in a triple system
We discuss the events that led to the giant eruption of Eta Carinae, and find that the mid-nineteenth century (in 1838-1843) giant mass-loss outburst has the characteristics of being produced by theExpand
An indication for the binarity of P Cygni from its 17th century eruption
I show that the 17th century eruption of the massive luminous blue variable (LBV) star P Cygni can be explained by mass transfer to a B-type binary companion in an eccentric orbit, under theExpand
Fast ejecta resulted from jet–wind interaction in the Great Eruption of Eta Carinae
The accretion model for the nineteenth century Great Eruption (GE) of $\eta$ Carinae suggests that mass outflowing from the primary was accreted onto the secondary, and the gravitational energy ofExpand
A revised historical light curve of Eta Carinae and the timing of close periastron encounters
The historical light curve of the 19th century ‘Great Eruption’ of"Carinae provides a striking record of the violent instabilities encountered by massive stars. In this paper, we report and analyseExpand
Simulating the formation of η Carinae’s surrounding nebula through unstable triple evolution and stellar merger-induced eruption
η Carinae is an extraordinary massive star famous for its 19th century Great Eruption and the surrounding Homunculus nebula ejected in that event. The cause of this eruption has been the centre ofExpand
Simulating the response of the secondary star of Eta Carinae to mass accretion at periastron passage

  • 2019
We use high resolution 3D hydrodynamical simulations to quantify the amount of mass accreted onto the secondary star of the binary system Eta Carinae, exploring two sets of stellar masses that hadExpand
ORBITAL PARAMETERS FOR THE 250M⊙ETA CARINAE BINARY SYSTEM
We show that recent observations of He I and N II lines of $\eta$ Carinae may provide support for an orbital orientation where the secondary star is closest to us at periastron passages. ThisExpand
The Orientation of Eta Carinae and the Powering Mechanism of Intermediate Luminosity Optical Transients (ILOTs)
Contrary to recent claims, we argue that the orientation of the massive binary system Eta Carinae is such that the secondary star is closer to us at periastron passages, and it is on the far sideExpand
The interaction of the eta carinae primary wind with a century old slow equatorial ejecta
Abstract We argue that the asymmetric morphology of the blue and red shifted components of the outflow at hundreds of AU from the massive binary system η Carinae can be understood from the collisionExpand
EXPLAINING THE SUPERNOVA IMPOSTOR SN 2009ip AS MERGERBURST
We propose that the energetic major outburst of the supernova (SN) impostor SN 2009ip in 2012 September (outburst 2012b) was a mergerburst event, where two massive stars merged. The previousExpand

Possible implications of mass accretion in Eta Carinae
Abstract We apply the previously suggested accretion model for the behavior of the super-massive binary system η Car close to periastron passages. In that model it is assumed that for ∼ 10 weeks nearExpand

Abstract We study the runaway mass loss process of major eruptions of luminous blue variables (LBVs) stars, such as the 1837–1856 Great Eruption of η Carinae. We follow the evolution of a massiveExpand
Comparing η 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 Car is on its way to becoming a supernova, the RedExpand
NGC 300 OT2008-1 as a Scaled-down Version of the Eta Carinae Great Eruption

The departure of η Carinae from axisymmetry and the binary hypothesis
I argue that the large-scale departure from axisymmetry of the η Carinae nebula can be explained by the binary star model of η Carinae. The companion diverts the wind blown by the primary star, byExpand

On the role of continuum-driven eruptions in the evolution of very massive stars and Population III stars
We suggest that the mass lost during the evolution of very massive stars may be dominated by optically thick, continuum-driven outbursts or explosions, instead of by steady line-driven winds. InExpand
