High mass accretion rates onto evolved stripped-envelope massive stars by jet-induced mass removal
Yotham Cohen, Ealeal Bear, Noam Soker
Simulating one-dimensional stellar evolution models with MESA, we show that removing the outer inflated envelope of a mass-accreting evolved stripped-envelope star, like a Wolf-Ray…
Jet-Driven Formation of Bipolar Rings in Planetary Nebulae: Numerical Simulations Inspired by NGC 1514
Muhammad Akashi, Ealeal Bear, Noam Soker
We conduct three-dimensional hydrodynamical simulations of jets launched into a dense shell, reproducing two rings in a bipolar structure that resemble the two dusty rings of the p…
Natal kick by early-asymmetrical pairs of jets to the neutron star of supernova remnant S147
Dmitry Shishkin, Ealeal Bear, Noam Soker
We analyze the bipolar morphology of the jet-shaped core-collapse supernova (CCSN) remnant (CCSNR) S147 and its neutron star (NS) kick velocity, and suggest that two pairs of unequ…
Enabling high mass accretion rates onto massive main sequence stars by outer envelope mass removal
Ariel Scolnic, Ealeal Bear, Noam Soker
Using the one-dimensional numerical code MESA, we simulate mass accretion at very high rates onto massive main sequence stars, M=30, 60, 80 Mo, and find that these stars can accret…
