Temporal Changes in the Infrared Spectra of Magellanic Carbon Stars
G. C. Sloan, K. E. Kraemer, B. Aringer +9
The Medium-Resolution Spectrometer on the Mid-Infrared Instrument on JWST obtained spectra of three carbon stars in the Large Magellanic Cloud. Two of the spectra differ significan…

High-Speed Outflows and Dusty Disks during the AGB to PN Transition: The PANORAMA survey
Raghvendra Sahai, Javier Alcolea, Bruce Balick +15
As mass-losing asymptotic giant branch (AGB) stars evolve to planetary nebulae (PNe), the mass outflow geometries transform from nearly spherical to extreme aspherical. The physica…

Chemical tracers of a highly eccentric AGB-main sequence star binary
T. Danilovich, J. Malfait, M. Van de Sande +32
Binary interactions have been proposed to explain a variety of circumstellar structures seen around evolved stars, including asymptotic giant branch (AGB) stars and planetary nebul…
