Scientific paper

The authors have performed speckle masking bispectrum observations of η Carinae at λ ≡ 850 nm with the 2.2-m ESO/MPG telescope. The reconstructed diffraction-limited image shows that η Carinae consists of one dominant star and three fainter star-like objects at separations of 0.21arcsec, 0.18arcsec, and 0.11arcsec. The three faint objects are ≡12-times fainter than the dominant star. The diameter of all four objects is <0.03arcsec.
