The mass of a star is the most fundamental parameter for its structure, evolution, and final
fate. It is particularly important for any kind of stellar archaeology and characterization of …

Here I review the current state of the field of optical stellar interferometry, concentrating on
ground-based work although a brief report of space interferometry missions is included. We …

The characterization of exoplanets is critical to understanding planet diversity and formation,
their atmospheric composition, and the potential for life. This endeavour is greatly enhanced …

We have observed Mira stars with the FLUOR beamcombiner on the IOTA interferometer in
narrow bands around m wavelength. We find systematically larger diameters in bands …

We report the observations in the K band of the red supergiant star α Orionis and of the
bright giant star α Herculis with the FLUOR beamcombiner at the IOTA interferometer. The …

We present first results of an experiment to combine data from Keck aperture masking and
the Infrared-Optical Telescope Array to image the circumstellar environments of evolved …

We present new total intensity and linear polarization VLBA observations of the and maser
transitions of SiO at 42.8 and 43.1 GHz in a number of Mira variable stars over a substantial …

We present four model series of the codex dynamical opacity-sampling models of Mira
variables with solar abundances, designed to have parameters similar to o Cet, R Leo and R …

We have measured nonzero closure phases for about 29% of our sample of 56 nearby
asymptotic giant branch (AGB) stars, using the three-telescope Infrared Optical Telescope …

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 …
