Counteracting Tidal Circularization with the Grazing Envelope Evolution
Amit Kashi, Noam Soker
We show that substantially enhanced mass loss at periastron passages, as is expected in the grazing envelope evolution (GEE), can compensate for the circularization effect of the t…
Simulations and Modeling of Intermediate Luminosity Optical Transients and Supernova Impostors
Amit Kashi
More luminous than classical novae, but less luminous than Supernovae, lies the exotic stellar eruptions known as Intermediate luminosity optical transients (ILOTs). They are divid…
Periodicity in the Light Curve of P Cygni - Indication for a Binary Companion?
Amir M. Michaelis, Amit Kashi, Nino Kochiashvili
We use observations of the Luminous Blue Variable (LBV) P Cygni spanning seven decades, along with signal processing methods, to identify a periodicity in the stellar luminosity. W…
Simulating the Response of the Secondary Star of Eta Carinae to Mass Accretion at Periastron Passage
Amit Kashi
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…
Common envelope jets supernova (CEJSN) impostors resulting from a neutron star companion
Avishai Gilkis, Noam Soker, Amit Kashi
We propose a new type of repeating transient outburst initiated by a neutron star (NS) entering the envelope of an evolved massive star, accreting envelope material and subsequentl…
The orientation of Eta Carinae and the powering mechanism of intermediate luminosity optical transients (ILOTs)
Amit Kashi, Noam Soker
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 passage, and it is o…
