Bubbles in Planetary Nebulae and Clusters of Galaxies: Instabilities at Bubble Fronts
Noam Soker
I study the stability of off-center low-density more or less spherical (fat) bubbles in clusters of galaxies and in planetary nebulae (PNs) to Rayleigh-Taylor (RT) instability. As…
Energy and Angular Momentum Deposition During Common Envelope Evolution
Noam Soker
I consider three processes which enhance mass loss rate from a common envelope of a giant star with a main sequence or a white dwarf companion spiraling-in inside its envelope. I c…
Cooling by Heat Conduction Inside Magnetic Flux Loops and the Moderate Cluster Cooling Flow Model
Noam Soker
I study non-radiative cooling of X-ray emitting gas via heat conduction along magnetic field lines inside magnetic flux loops in cooling flow clusters of galaxies. I find that such…
The Egg Nebula (AFGL 2688): Deepening Enigma
Joel H. Kastner, Noam Soker
Recent observations of the Egg Nebula (AFGL 2688), obtained at ever-increasing spatial and spectral resolution, have revealed a perplexing array of phenomena. Many of these phenome…
Influence of Planets on Parent Stars: Angular Momentum
Noam Soker
I review some possible processes by which planets and brown dwarfs can influence the evolution of their parent evolved stars. As sun-like stars evolve on the red giant branch (RGB)…
Bubbles in Planetary Nebulae and Clusters of Galaxies: Jet Properties
Noam Soker
I derive constraints on jet properties for inflating pairs of bubbles in planetary nebulae and clusters of galaxies. This work is motivated by the similarity in morphology and some…
