Simulating the shaping of point-symmetric structures in the jittering jets explosion mechanism
Jessica Braudo, Amir Michaelis, Muhammad Akashi +1
We conduct three-dimensional hydrodynamical simulations of core-collapse supernovae by launching several pairs of jets into a collapsing core model and show that the jittering jets…
Rapid decline in the lightcurves of luminous supernovae by jet-driven bipolar explosions
Muhammad Akashi, Amir Michaelis, Noam Soker
We calculate the lightcurves of jet-driven bipolar core collapse supernova (CCSN) explosions into a bipolar circumstellar mater (CSM) and show that an equatorial observer finds the…
Accretion in massive colliding wind binaries and the effect of wind momentum ratio
Amit Kashi, Amir Michaelis, Yarden Kaminetsky
We carry out a numerical experiment of ejecting winds in a massive colliding wind binary system, and quantifying the accretion onto the secondary star under different primary mass…
The Grand Canonical Multiverse and the Small Cosmological Constant
Ido Ben-Dayan, Merav Hadad, Amir Michaelis
We consider the Multiverse as an ensemble of universes. Using standard statistical physics analysis we get that the Cosmological Constant (CC) is exponentially small. The small and…
ASASSN-13db 2014-2017 Eruption as an Intermediate Luminosity Optical Transient
Amit Kashi, Amir M. Michaelis, Leon Feigin
The low mass star ASASSN-13db experienced an EXor outburst in 2013, which identified it as a Young Stellar Object (YSO). Then, from 2014 to 2017 it had another outburst, longer and…
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…
