Eta Carinae resolved by speckle interferometry*
G. Weigelt und J. EbersbergerAbstract
Digital speckle interferometric observations of Eta Carinae
were performed at wavelengths of 820 and 850 nm with the 3.6-m and 2.2-m
telescope at ESO. Four star-like components (stars or gas clouds) were
resolved for the first time. The diameter of all four components is
less than 0.03 arcsec. The field size of the reconstructed autocorrelation
is about 0.8 arcsec. The separations of the components A2, A3 and A4
relative to the brightest component A1 are 0.18, 0.22 and 0.09 arcsec,
Speckle masking observations of eta Carinae
Hofmann, K.-H., Weigelt, G.
We have performed speckle masking observations of eta Carinae at 850 nm with the 2.2m ESO/MPG telescope. The reconstructed diffraction-limited image shows that eta Carinae consists of one dominant star and three fainter star-like objects at separations of 0.21'', 0.18'' and 0.11''. The three faint objects are ~12 times fainter than the dominant star. The diameter of all four objects is <0.03".
