The Mira variable S Orionis: relationships between the photosphere, molecular layer, dust shell, and SiO maser shell at 4 epochs
Aims. We present the first multi-epoch study that includes concurrent mid-infrared and radio interferometry of an oxygen-rich Mira star. Methods. We obtained mid-infrared interferometry of S Ori withExpand
Joint VLBA/VLTI Observations of the Mira Variable S Orionis
We present the first coordinated Very Long Baseline Array (VLBA) / Very Large Telescope Interferometer (VLTI) measurements of the stellar diameter and circumstellar atmosphere of a Mira variableExpand
The Carbon-rich Dust Sequence: Infrared Spectral Classification of Carbon Stars
We have developed a classification system for the infrared spectral emission from carbon stars, using a sample of 96 bright carbon-rich variables associated with the asymptotic giant branch. InExpand
New insights into the dust formation of oxygen-rich AGB stars
Context. Asymptotic giant branch (AGB) stars are one of the major sources of dust in the universe. The formation of molecules and dust grains and their subsequent expulsion into the interstellarExpand
J, H, K spectro-interferometry of the Mira variable S Orionis
Aims. We present J, H, K spectrally dispersed interferometry with a spectral resolution of 35 for the Mira variable S Orionis. We aim at measuring the diameter variation as a function of wavelengthExpand
Infrared high angular resolution measurements of stellar sources. VI. Accurate angular diameters of X Cnc, U Ori and Eta Gem
We present the results of near-IR lunar occultation measurements of three well-known, large angular diameter, cool giant stars, namely X Cnc (CII), U Ori (M8III) and η Gem (M3III). Their 2.2 μ mExpand
Mid-Infrared Observations of Mass-Losing Red Giants
Within the past 3 years, mid-ir imagers have become available at 10-meter class telescopes. As a result, it is now possible to spatially resolve many sources which previously appeared to beExpand
The Massive Disk around OH 231.8+4.2
We have obtained 11.7 and 17.9 μm images at the Keck I telescope of the circumstellar dust emission from OH 231.8+4.2, an evolved mass-losing red giant with a well-studied bipolar outflow. We detectExpand
R Aquarii: Evidence for Differential Rotation of the SiO Maser Shell
We previously reported Very Large Array and Berkeley-Illinois-Maryland Association (BIMA) array observations that suggested rotation of the SiO maser shell surrounding the long-period variable (LPV)Expand
Mass Loss from Cool Stars: Impact on the Evolution of Stars and Stellar Populations
▪ Abstract This review emphasizes the mass loss processes that affect the fates of single stars with initial masses between one and nine solar masses. Just one epoch of mass loss has been clearlyExpand
