Relation of Observable Stellar Parameters to Mass-Loss Rate of AGB Stars in the LMC
Henry A. Prager, Lee Anne Willson, Massimo Marengo +1
Using the Riebel et al. (2012) data set for 6,889 pulsating AGB stars in the LMC, we have derived formulae for mass-loss rate as a function of luminosity and pulsation period or lu…
What do we really know about mass loss on the AGB?
L. A. Willson
Mass loss rate formulae are derived from observations or from suites of models. For theoretical models, the following have all been identified as factors greatly influencing the at…
First Surface-resolved Results with the IOTA Imaging Interferometer: Detection of Asymmetries in AGB stars
S. Ragland, W. A. Traub, J. -P. Berger +20
We have measured non-zero closure phases for about 29% of our sample of 56 nearby Asymptotic Giant Branch (AGB) stars, using the 3-telescope Infrared Optical Telescope Array (IOTA)…
Secular Evolution in Mira Variable Pulsations
M. R. Templeton, J. A. Mattei, L. A. Willson
Stellar evolution theory predicts that asymptotic giant branch stars undergo a series of short thermal pulses that significantly change their luminosity and mass on timescales of h…
The Self-Regulated Winds of Long Period Variable Stars
Curtis Struck, Daniel C. Smith, Lee Anne Willson +2
Numerical models of the extended atmospheres of long period variable or Mira stars have shown that their winds have a very simple, power law structure when averaged over the pulsat…
Continuous and Burst-like Accretion onto Substellar Companions in Mira Winds
Curtis Struck, Babak E. Cohanim, Lee Anne Willson
We present numerical hydrodynamical modeling of the effects of a giant planet or brown dwarf companion orbiting within the extended atmosphere and wind formation zone of an approxi…
