A circumbinary disc in the final stages of common envelope and the core-degenerate scenario for Type Ia supernovae
We study the final stages of the common envelope (CE) evolution and find that a substantial fraction of the ejected mass does not reach the escape velocity. To reach this conclusion we use aExpand

FORMATION OF BIPOLAR PLANETARY NEBULAE BY INTERMEDIATE-LUMINOSITY OPTICAL TRANSIENTS
We present surprising similarities between some bipolar planetary nebulae (PNe) and eruptive objects with peak luminosity between novae and supernovae. The latter group is termed ILOT forExpand

Reverberation Mapping of the Broad Line Region: application to a hydrodynamical line-driven disk wind solution
The latest analysis efforts in reverberation mapping are beginning to allow reconstruction of echo images (or velocity-delay maps) that encode information about the structure and kinematics of theExpand

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

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

The source of the helium visible lines in η Carinae
Abstract We assume that the helium-I lines emitted by the massive binary system η Carinae are formed in the acceleration zone of the less-massive secondary star. We calculate the Doppler shift of theExpand

EXPLAINING THE EARLY EXIT OF ETA CARINAE FROM ITS 2009 X-RAY MINIMUM WITH THE ACCRETION MODEL
We use the accretion model to explain the early exit of {eta} Car from its 2009 X-ray minimum. In the accretion model, the secondary star accretes mass from the primary wind near periastron passage,Expand

Explaining the Type Ia supernova PTF 11kx with a violent prompt merger scenario
We argue that the multiple shells of circumstellar material (CSM) and the supernovae (SN) ejecta interaction with the CSM starting 59 days after the explosion of the Type Ia SN (SN Ia) PTF 11kx, areExpand

The orientation of the ? Carinae binary system
We examine a variety of observations that shed light on the orientation of the semimajor axis of the η Carinae massive binary system. Under several assumptions, we study the following observations:Expand

An intermediate luminosity optical transient (ILOTs) model for the young stellar object ASASSN-15qi
We construct a scenario where the outburst of the young-stellar-object ASASSN-15qi is an intermediate luminosity optical transient (ILOT). In this scenario a sub-Jupiter young planet was tidallyExpand
