Scientific paper

We present new near-infrared speckle interferometric observations of the young stellar object Elias 1. The emission is resolved into a narrow east-west elongated blue halo (FWHM about 0.2"x1.0") and an unresolved core (FWHM<0.2"). Previously, Kataza and Maihara (1991A&A...248L...1K) had inferred an east-west elongated optically thin disk within which the NIR light is directly scattered. Adding new pieces to the puzzle may alter the scenario in favor of scattering in bipolar lobes with a polar axis oriented east-west.
