First results with the IOTA3 imaging interferometer: The spectroscopic binaries lambda Vir and WR 140
J. D. Monnier, W. Traub, F. P. Schloerb +26
We report the first spatially-resolved observations of the spectroscopic binaries lambda Vir and WR 140, which includes the debut of aperture-synthesis imaging with the upgraded th…
