Dynamos and Chemical Mixing in Evolved Stars
J. Nordhaus, E. G. Blackman
In low-mass Red Giant Branch (RGB) and Asymptotic Giant Branch (AGB) stars, anomalous mixing must transport material near the hydrogen-burning shell to the convective envelope. Rec…
A Grand Challenge for Planetary Nebulae
Adam Frank, Orsola De Marco, Eric Blackman +1
The study of PN has been confronting a growing list of dilemmas which have yet to find coherent resolution. These issues are both observational and theoretical and can be stated as…
Planetary Nebulae Principles & Paradigms: Binaries, Accretion, Magnetic Fields
Eric G. Blackman, Jason T. Nordhaus
Observations suggest that many, if not all, post AGB systems evolve through an aspherical outflow phase. Such outflows require a sufficient engine rotational energy which binaries…
The Formation of Crystalline Dust in AGB Winds from Binary Induced Spiral Shocks
R. G. Edgar, J. Nordhaus, E. Blackman +1
As stars evolve along the Asymptotic Giant Branch, strong winds are driven from the outer envelope. These winds form a shell, which may ultimately become a planetary nebula. Many p…
On the role of stochastic Fermi acceleration in setting the dissipation scale of turbulence in the interstellar medium
Robert I Selkowitz, Eric G. Blackman
We consider the dissipation by Fermi acceleration of magnetosonic turbulence in the Reynolds Layer of the interstellar medium. The scale in the cascade at which electron accelerati…
Toward Coupling Flow Driven and Magnetically Driven Dynamos
Eric G. Blackman
Most large scale dynamo research for astrophysical rotators focuses on interior flow driven helical dynamos (FDHDs), but larger scale coronal fields most directly influence observa…
