Red supergiants as potential Type IIn supernova progenitors: Spatially resolved 4.6 micron CO emission around VY CMa and Betelgeuse
Nathan Smith, Kenneth H. Hinkle, Nils Ryde
We present high-resolution 4.6micron CO spectra of the circumstellar environments of two RSGs that are potential SN progenitors: Betelgeuse and VY CMa. Around Betelgeuse, 12CO emis…
Infrared Spectroscopy of Symbiotic Stars. VII. Binary Orbit and Long Secondary Period Variability of CH Cygni
Kenneth Hinkle, Francis Fekel, Richard Joyce
High-dispersion spectroscopic observations are used to refine orbital elements for the symbiotic binary CH Cyg. The current radial velocities, added to a previously published 13 ye…
Post-Outburst Observations of V1647 Ori: Detection of a Brief Warm, Molecular Outflow
Sean Brittain, Terrence Rettig, Theodore Simon +4
We present new observations of the fundamental ro-vibrational CO spectrum of V1647 Ori, the young star whose recent outburst illuminated McNeil's Nebula. Previous spectra, acquired…
Abundances in intermediate-mass AGB stars undergoing third dredge-up and hot-bottom burning
J. A. McSaveney, P. R. Wood, M. Scholz +2
High dispersion near-infrared spectra have been taken of seven highly-evolved, variable, intermediate-mass (4-6 Msun) AGB stars in the LMC and SMC in order to look for C, N and O v…
