Is the Milky Way ringing? The hunt for high velocity streams
I. Minchev, A. C. Quillen, M. Williams +4
We perform numerical simulations of a stellar galactic disk with initial conditions chosen to represent an unrelaxed population which might have been left following a merger. Stars…
Magnetic Mixing in Red Giant and Asymptotic Giant Branch Stars
J. Nordhaus, M. Busso, G. J. Wasserburg +2
The available information on isotopic abundances in the atmospheres of low-mass Red Giant Branch (RGB) and Asymptotic Giant Branch (AGB) stars requires that episodes of extensive m…
Towards a Spectral Technique for Determining Material Geometry Around Evolved Stars: Application to HD 179821
J. Nordhaus, I. Minchev, B. Sargent +6
HD 179821 is an evolved star of unknown progenitor mass range (either post-Asymptotic Giant Branch or post-Red Supergiant) exhibiting a double peaked spectral energy distribution (…
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…
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…
