Shaping Planetary Nebulae by Light Jets
Muhammad Akashi, Noam Soker
We conduct numerical simulations of axisymmetrical jets expanding into a spherical AGB slow wind. The three-dimensional flow is simulated with an axially symmetric numerical code.…
X-Ray Emission from Jet-Wind Interaction in Planetary Nebulae
Muhammad Akashi, Yohai Meiron, Noam Soker
We conduct 2D numerical simulations of jets expanding into the slow wind of asymptotic giant branch stars. We show that the post-shock jets' material can explain the observed exten…
Shaping Planetary Nebulae by Jets
Muhammad Akashi
We conduct 2D axisymmetrical hydrodynamical simulations to investigate the interaction of a collimated fast wind (CFW; wide jets) with a spherical AGB wind. The code includes radia…
A Model for the Formation of Large Circumbinary Disks Around Post AGB Stars
Muhammad Akashi, Noam Soker
We propose that the large, radius of ~1000 AU, circumbinary rotating disks observed around some post-asymptotic giant branch (post-AGB) binary stars are formed from slow AGB wind m…
X-Ray Emission from Planetary Nebulae Calculated by 1D Spherical Numerical Simulations
Muhammad Akashi, Noam Soker, Ehud Behar +1
We calculate the X-ray emission from both constant and time evolving shocked fast winds blown by the central stars of planetary nebulae (PNs) and compare with observations. Using s…
Accretion onto the Companion of Eta Carinae During the Spectroscopic Event: II. X-Ray Emission Cycle
Muhammad Akashi, Noam Soker, Ehud Behar
We calculate the X-ray luminosity and light curve for the stellar binary system Eta Carinae for the entire orbital period of 5.54 years. By using a new approach we find, as suggest…
